Title:
The Present and Future of Gravitational Wave Astrophysics: A Summary of Team Taiwan
Abstract
The breakthrough detection of gravitational wave by LIGO in 2015 has revolutionised our understanding of the universe. This not only confirms the existence of gravitational waves, they also provide direct evidence of binary black hole systems. Since then, 90 gravitational wave events have been found by LIGO and Virgo. In 2020 April, the Japanese underground gravitational wave detector, KAGRA, conducted the first observing run. Taiwan has played a significant role in the KAGRA collaboration and we are leading some of the key developments. LIGO, Virgo, and KAGRA will start the next joint observing run from 2022 December after an upgrade of the instruments. In this talk, I will summarise some of the key results in previous 3 observing runs and contributions from Taiwan.

Title:
Natural Negative-Refractive-Index Materials
Abstract
Our calculation shows that negative refractive index (NRI), which was known to exist only in metamaterials in the past, can be found in Dirac semimetals (DSM). Electrons in DSM have zero effective mass and hence the system carries no nominal energy scale. Therefore, unlike those of ordinary materials, the electromagnetic responses of the electrons in DSM will not be overwhelmed by the physical effects related to electron mass. NRI is induced by the combination of the quantum effect of vacuum polarization and its finite temperature correction which is proportional to T 4 at low temperature. It is a phenomenon of resonance between the incident light and the unique structure of Dirac cones, which allows numerous states to participate in electron-hole pair production excited by the incident light with similar dispersion relation to that of Dirac cones. NRI phenomenon of DSM manifests in an extensive range of photon frequency and wave number and can be observed around giga Hertz range at temperature slightly higher than room temperature.

Title:
Study of Superconductivity—A Personal Research Journey
Abstract
My research career started from the search for materials to realize the interfacial superconductivity, particularly based on the idea of the exciton-mediated superconductivity at metal-semiconductor interface. There were several interesting projects related to this search including an idea using microgravity for material processing. An important work was on the perovskite oxide BaPb1-xBixO3, a solid-solution of semi-metallic BaPbO3 and insulating BaBiO3, which was considered to be an example of interfacial superconductor. This subject eventually led to the discovery of cuprate superconductors in late 1980. The excitement in cuprate superconductors extended for more than two decades then came to the discovery of Fe-based superconductors including FeSe, which was found in our laboratory. I shall present in more details our current understanding of the structural origin of superconductivity of FeSe and related compounds. Our results strongly suggest the coexistence of electronically metallic and semiconducting (or insulating) phases, but with the same crystal phase, in the system is the origin for superconductivity.

Title:
Exploring the optical signatures of momentum forbidden dark excitons in 2D materials
Abstract
With the exceptional spin-, valley-, and excitonic properties, monolayer transition-metal dichalcogenides (TMD’s) have drawn massive interest in both fundamental research and advanced opto-electronic applications for over a decade. Because of inherently enhanced Coulomb interactions in the low dimensionality, excitons in TMD monolayers are so tightly bound with the large binding energies of hundreds of meV and featured with complex exciton fine structures, composed of the states of bright exciton (BX), spin-forbidden (SF-DX) and various momentum-forbidden dark exciton (MF-DXs) as well. In particular, MF-DXs in TMD-MLs have been recently realized to be substantially crucial in various physical phenomena, e.g. fast energy-transfer dynamics, superior valley-polarization and long-lived lifetimes. In this talk, I will report on our recent comprehensive theoretical investigation of the excitonic fine structures of TMD-MLs, and our exploration in the intriguing dark-exciton physics in the 2D materials.

Title:
Nanoscale Physics in Living Systems Unveiled by Advanced Optical Microscopy
Abstract
Attempting to understand biology from a physics perspective is often considered incomplete, although the fundamental interactions between individual molecules can be well described by the physical laws. The challenge becomes clear when handling a mixture of biomolecules with great diversity, resulting in a complex and dynamic system where physical rules provide little help in explaining and predicting biological events at the macroscopic scale. This is because biophysics at the mesoscopic scale (1-1000 nm) is less understood primarily because the reliable data at the relevant spatial and temporal regimes are scarce. In this talk, I will show how an ultrahigh-speed optical microscope helps to study physics in biological systems at the nanoscale. The acquired data are unique for understanding the operation of living systems from the physical point of views. Examples of single-molecule and cell dynamics will be discussed.

Brain functional imaging with light
Abstract
In the 21st century, one of the grand challenges in science is to understand how a brain functions. Similar to a computer, a functional brain is composed of hardware and software. The major bottleneck lies in the difficulty to directly observe the brain “software”, i.e. the rule and operating information used by the brain, that might emerge from pan-neuron/synapse connectome. Technically, there is no existing tool that allows observation of dynamic responses of every neuron in a living brain. Our strategy for probing whole-brain functional connectome is to combine small model animal with optical microscopy that offers sub-cellular resolution. In this talk, I share our recent progress in enhancing 3D imaging speed of two-photon microscopy, which concurrently provides millimeter tissue penetration, toward the observation of functional connection maps in a living Drosophila.

Title:
Some new concepts in astrochemistry using para-hydrogen matrix isolation
Abstract
Para-hydrogen (p-H2) matrix isolation has emerged as a wonderful technique for various applications in free-radical spectroscopy, atmospheric chemistry, and astrochemistry because of the unique characteristics associated with this quantum solid. We present two types of applications in astrochemistry using p-H2 in this talk.
(1) Production of protonated and hydrogenated species— Protonated polycyclic aromatic hydrocarbons (PAH) are possible carriers of the unidentified IR emission in the interstellar media. The electron-bombardment experiments in p-H2 provide an excellent tool to produce and identify these protonated species. The IR spectra of 1-quinolinium cation (C9H7NH+) and 1-quinolinyl radical (C9H7NH), produced upon electron bombardment during deposition of a mixture of quinoline (C9H7N) and p-H2 at 3.2 K, indicate that the protonation and hydrogenation occur mainly at the N-atom site. Additional experiments on irradiation of C9H7N/Cl2/p-H2 matrices at 365 nm were performed to induce the reaction H + C9H7N. We identified, in addition to C9H7NH, four radicals (3-, 4-, 7-, and 8-HC9H7N) with hydrogenation at the C-atom site.
(2) New concept of hydrogen reactions in astrochemistry—Hydrogen reactions play important roles in astrochemistry; H + methylamine (CH3NH2) serves as a good example. We performed this reaction in solid p-H2 and observed IR spectra of •CH2NH2 and CH2NH on irradiation and when the matrix was maintained in darkness. Observation of IR spectrum of •CH2NH2 clearly indicates that •CH2NH2, a precursor of glycine, can be formed from H + CH3NH2 in dark interstellar clouds. The observed dual-cycle mechanism containing two H-abstraction and H-addition steps chemically connects CH3NH2 and CH2NH and explains their quasi-equilibrium. We performed also reactions of H atoms with trans-NMF in p-H2 at 3.3 K and found that isomer cis-NMF, which has higher energy, increased continuously in darkness; H addition to CH3NCO produced only cis-radicals that led to cis-NMF. Furthermore, H-atom-induced fragmentation in darkness by breaking the C−C bond provides links between NMF and HCNO/CH2NH. These new types of reactions were overlooked previously in astrochemistry.

Space, time, matter, and strings
Abstract
The Standard Model of elementary particles is known experimentally to be
very good up to energies of about 2 TeV. Theoretical investigations of
the behavior at even higher energies show that it is consistent up to
the Planck scale. This raises the very simple possibility that string
theory can be directly connected to the Standard Model at the Planck
scale. Possible future directions in particle theory under such
assumptions will be discussed.

Search for the Darkmatter from TeV to µeV
Abstract
Darkmatter is one of the most important unsolved problems in physics today. However, so far there is no evidence of particle darkmatter from laboratory experiments. Many theoretical models have inspired experimental searches with novel techniques. In this talk, I present two Darkmatter search programs that I have been involved, which look for Darkmatter particles in GeV-TeV/c2 and µeV/c2 masses, respectively. The experimental techniques are widely different and the interpretation of the results are subjects to large uncertainties. On the other hand, the instrumentation developments through these projects provide strong motivations to continue these types of “blind” search strategy.

Title:
Electron and magnetic turbulence fluctuations in the interstellar medium measured by scintillations of pulsar radio waves and in-situ Voyagers 1 & 2 observations
Abstract
In 1941, Kolmogorov proposed the first hydrodynamic turbulent model for the fluid and gave the well-known power law index, -11/3, of energy spectrum. In 1976, Lee and Jokipii first suggested that the interstellar turbulence at the length scale λ of 108m to 1018m (100 light-years) also has a Kolmogorov-like spectrum based on observations of radio wave scintillations and interstellar clouds. Armstrong et al. (1995) constructed the composite spectrum extending from 106m to 1018m based on ground telescope observational results. In 1977, two satellites named Voyager 1 & 2 were launched. Voyager 1 (2) entered the local interstellar medium in 2012 (2018). Kun-Han Lee and Lou Lee (2019) uses the data from in situ measurements to determine the spectrum of the turbulent density fluctuations from 50m to 2x1012m (15 au) in the local interstellar medium. By combining the in situ measured spectrum and the earlier remote observed data, they obtain a composite spectrum, the Grand Power Law in the Milky Way, extending from 50m to 1018m (100 light-years), over 16 orders of magnitude in length scale. In this talk, the interaction of solar wind with Earth’s magnetosphere and with interstellar medium will also be discussed.
