Discovering the Dark Universe with Artificial Intelligence
đź“ąđź—Ž
Host: Pao-Ti Chang
Time: 2:20 pm - 4:20 pm
Place: Room 104, CCMS-New Phys. building
Abstract
Compelling experimental evidence strongly supports searches for new particles predicted by theories Beyond the Standard Model (BSM). Such searches are connected to fundamental questions among the highest priorities of particle physics like dark matter baryogenesis and hierarchy problems. At the Large Hadron Collider (LHC) the ATLAS experiment is ideally suited for detecting heavy states like heavy Higgs and dark scalars that decay to particles with high transverse momentum (pT) to the beam. In this talk I will present the state-of-the-art heavy Higgs and dark scalar searches in ATLAS. Specifically I will highlight how Artificial Intelligence plays a role to advance and expand the LHC physics program. This includes the improvement of on-going analyses through novel algorithm developments and new opportunities for discovery with accelerated Machine Learning which can address big data challenges from the upcoming High-Luminosity LHC.

Quantum Sensing with Cold Atoms
Host: Pao-Ti Chang
Time: 2:20 pm - 4:20 pm
Place: Room 104, CCMS-New Phys. building
Abstract
We currently find ourselves amidst the second quantum revolution, which seeks to translate quantum research into technological advancements across a wide spectrum of fields, encompassing sensing, computing, and communications. Among the various quantum systems, cold atomic vapor stands out as a leading platform in numerous groundbreaking experiments. Nonetheless, miniaturizing a cold atomic system often comes at the cost of reduced performance, thereby restricting its practical applications. In the forthcoming discussion, I will outline our endeavors in miniaturizing a cold-atom laboratory within a hollow-core photonic crystal fiber, while preserving its operational excellence. This work holds the potential to open new avenues for short-distance quantum sensing.
In the latter part of this presentation, I will showcase our research in the realm of quantum optics involving mechanical atomic oscillators within optical lattices. This includes generating Schrödinger cat states, achieving instantaneous quantum squeezing that defies the quantum speed limit, and realizing two-mode squeezed states. These outcomes offer promising insights into quantum sensing and the utilization of continuous-variable quantum information within noisy harmonic oscillators.

Are the Standard-Model Parameters Free?
đź“ąđź—Ž
Host: Pao-Ti Chang
Time: 2:20 pm - 4:20 pm
Place: Room 104, CCMS-New Phys. building
Abstract
Contrary to what was taught in textbooks, we demonstrate that at least some of the Standard-Model (SM) parameters are not free, but constrained dynamically by analyticity for internal consistency of the theory. As an example, we show that the mixing angles and fermion masses can be constrained by the dispersion relations for mixing phenomena. An important prediction from our formalism is that the neutrino masses in the normal hierarchy, instead of in the inverted hierarchy or quasi-degenerate spectrum, match the observed Pontecorvo-Maki-Nakagawa-Sakata matrix elements. The lepton mixing angles larger than the quark ones can also be explained.

The Alchemy of Vacuum: Exploring Quantum Electrodynamic Effects in Chemistry
Host: Pao-Ti Chang
Time: 2:20 pm - 4:20 pm
Place: Room 104, CCMS-New Phys. building
Abstract
In this talk, I will briefly introduce my latest development in an emerging field “QED chemistry”. In the past few years, exploring chemical processes induced by vacuum electromagnetic fields has attracted considerable attention because the entry of quantum electrodynamics (QED) into chemistry is a new concept in fundamental chemistry. Quantum light can affect molecules in various aspects, and I will cover four different research topics (i) molecular fluorescence, (ii) resonance energy transfer, (iii) electron transfer, and (iv) non-adiabatic electromagnetic vacuum fluctuations.
First, in the framework of macroscopic QED, I developed a unified theory of molecular fluorescence, which enables us to describe the dynamics of molecular fluorescence coupled to quantum light from weak to strong light-matter couplings in a complicated dielectric environment. Based on this theory, we derived a parameter-free formula which can be used to estimate the exciton-polariton coupling for single molecules in a nanostructure. Our theory is in good agreement with the reported experimental results [Chikkaraddy et al., Nature 2016, 535, 127-130]. Second, I developed a unified theory of radiative and non-radiative resonance energy transfer based on macroscopic QED. The proposed theory allows us to describe long-range resonance energy transfer between two entities in spatially dependent vacuum electric fields. Third, we generalized famous Marcus theory and developed a theory of electron transfer based on conventional QED. Our theory shows that QED effects can significantly enhance the kinetic rate of electron transfer reactions by several orders of magnitude in the absence of cavities, which is implicitly supported by experimental reports. Fourth, we generalized the internal conversion theory at the first level in the framework of cavity QED by including the effects of non-adiabatic electromagnetic vacuum fluctuations. Our theory shows that, even without strong light-matter coupling, non-adiabatic QED effects can significantly influence the internal conversion rates.

Roaming in the Landscape of Chemical Dynamicsđź“ą
Host: Pao-Ti Chang
Time: 2:20 pm - 4:20 pm
Place: Room 104, CCMS-New Phys. building
Abstract
With recent developments of sophisticated experimental techniques and advanced theoretical methods/computations, the field of chemical reaction dynamics has reached to the point that theory‒experiment comparisons can be made at a quantitative level for a few prototypical A + BC systems. As the system becomes larger, more degrees of freedom are involved and the complexity increases exponentially. Yet, the multifaceted nature of polyatomic systems also opens the possibilities for observing many new physics/chemistry and novel phenomena―a land of opportunities―as Philip. W. Anderson advocated fifty years ago: More is Different (Science, 1972). In this talk, I shall recall how my laboratory at IAMS wondered from studying A + BC to toying small polyatomic system: the reactions of methane + X (X: F, Cl, O(3P), and OH). This effort shifts the paradigm in the field of reaction dynamics by making the methane (CH4) reaction a benchmark. Some of the key concepts introduced and unexpected phenomena uncovered will be highlighted. Those findings not only enrich our understanding of the studied reactions at the most fundamental level and inspire the theoretical developments, but also shape our thinking and lay the foundation for future explorations of different aspects of the multifaceted nature of polyatomic reactivity.

When Are Planets Formed?
Probing the Earliest Stage of Planet Formation
đź“ą
Host: Pao-Ti Chang
Time: 2:20 pm - 4:20 pm
Place: Room 104, CCMS-New Phys. building
Abstract
Planet formation is one of the hottest topics in the 21st century astrophysics. It is well known that disks are formed around young stars in the course of star formation, and planets are formed in these disks. Recent high angular resolution observations have revealed that many of disks around pre-main-sequence (PMS) stars have substructures, such as gaps or rings, which are signs of ongoing planet formation or even hidden protoplanets. Ubiquitous substructures in disks around PMS stars may suggest that planet formation has initiated in a stage earlier than the PMS phase, i.e., the protostellar phase. In order to probe the earliest stage of planet formation, we have to observe younger disks around protostars. With this motivation we have carried out the Large Program “Early Planet Formation in Embedded Disks (eDisk)” using Atacama Millimeter and submillimeter Array (ALMA) to systematically observe disks around 19 protostellar systems in nearby (d < 200 pc) star forming regions at a resolution of ~7 au. The Large Program has two main scientific objectives; (1) to search for substructures in disks around protostars, exploring possible early planet formation around protostars, (2) to search for Keplerian motions in disks, enabling to derive dynamical masses of the central protostars. The observations made in 1.3 mm continuum emission have revealed that disks around protostars have less distinctive substructures and more brightness asymmetries in marked contrast to disks around PMS stars. This remarkable difference in disks between protostars and PMS stars may suggest that planet formation quickly progresses when protostars evolve into PMS stars. In this talk, I will describe more details of the eDisk program, including its background, and will highlight initial results of the program.

High-Brightness and Narrow-Linewidth Source of Heralded Single Photons Generated from a Hot Atomic Vapor
đź—Ž
Host: Pao-Ti Chang
Time: 2:20 pm - 4:20 pm
Place: Room 104, CCMS-New Phys. building
Abstract
Optical qubits are made of single photons. Due to photons’ excellent fidelity, we can expect that optical qubits or single photons will play a more important role in future quantum communication. As single photons are generated one by one, they appear randomly and it is difficult to utilize qubits in random timing. Therefore, the practical operation method is to generate a pair of single photons, i.e., biphoton. The first photon of a pair heralds the coming of the second photon of the same pair, which is the heralded single photon for a subsequent quantum operation.
We employed a hot atomic vapor to generate biphotons. For the first time, the all-copropagation scheme was utilized in our system, resulting in an excellent phase match. The phase-match scheme enables us to make the linewidth of the single-photon wave packets as narrow as 290 kHz. This is the world record for the narrowest linewidth of single-mode single photons generated from room-temperature or hot media. We increased the spectral brightness of biphotons to 3.8Ă—105 pairs/s/MHz. This spectral brightness is the best result to date among all kinds of media such as hot or cold atomic vapors, solid crystals, and integrated photonic chips. A biphoton source of a higher generation rate can produce information carriers faster for a higher bandwidth of information transmission. A quantum operation utilizing biphotons of a narrower linewidth can achieve a better efficiency. Hence, the generation rate per linewidth, i.e., spectral brightness, is an important figure of merit of a biphoton source, and strongly influences the success rate of quantum information transmission. This source can become a key component in the future quantum network.

Abstract
Carbon nanotube is a rolled-up graphene sheet into a cylinder. The diameter of a carbon nanotube is 0.5-2nm and the length of the nanotube can be 100nm-10cm. Because of variety of possible helical geometries known as chirality, carbon nanotubes provide a family of structures that are expressed by two integers (n,m). In particular, depending on (n,m), a single-wall carbon nanotube is either metal or semiconductor.

What Can QFT Teach Us about Black Holes (and Vice Versa) ?
đź“ą
Host: Pao-Ti Chang
Time: 2:20 pm - 4:20 pm
Place: Room 104, CCMS-New Phys. building
Abstract
The existence of black holes is a remarkable prediction of Einstein's General Theory of Relativity. The prediction was spectacularly confirmed by the detection at LIGO in 2015 of the gravitational waves emitted by a black hole merger. Despite this, the status of black holes in a more complete description of our universe including quantum mechanics has long remained mysterious, presenting puzzles for theorists which still remain unsolved.
The AdS/CFT Correspondence is a "holographic" duality between gravity and quantum field theory (QFT) which has provided new tools for studying the physics of black holes. It has also led to progress in understanding the behaviour of QFT at strong coupling.
In my talk, I will review the correspondence and some of the insights it has provided. I will also discuss the future prospects for resolving some of the hardest outstanding questions.
