Optical technologies for new discoveries in life sciences: Multiphoton microscopy, Raman imaging and Optical Coherence Tomography
Speaker: Aart Verhoef (Texas A&M University)
I will discuss our most recent experimental results from a few different experiments. First, I will show how we use simultaneous 2- and 3 photon imaging to study the biology of anti-fungal compounds produced by soil bacteria, followed by results on the development of super-resolution multiphoton microscopy. Second, I will [...]
The Black Hole Mass – Stellar Velocity Dispersion Relation of 105 Month Swift-BAT Type 1 AGNs
Speaker: Turgay Caglar (Texas A&M University)
We present two independent measurements of stellar velocity dispersions (σ) from the Ca II H+K λ3969, 3934 and Mg I b λ 5183, 5172, 5167 region (3880-5550 Å) and the calcium triplet region (8350-8750 Å) for 173 hard X-ray-selected Type 1 active galactic nuclei (AGNs; z ≤ 0.08) from the [...]Stellar Populations and Ionized Gas in the Local Universe
Speaker: Ray Garner (Texas A&M University)
How do galaxies evolve? This is at first a seemingly simple and fundamental question, yet it is a question laced with intricacies. To help unravel the mystery of galaxy evolution, I present some of my thesis work, where I used deep narrowband imaging to investigate the nearby M101 Group. Namely, [...]
The Fable of the Unstable Neutrinos
Speaker: Srubabati Goswami (Physical Research Laboratory)Host: Doojin Kim/Bhaskar Dutta
Neutrino decay is governed by a non-Hermitian effective Hamiltonian and in general the mass eigenstates and decay eigenstates are not the same. This mismatch is inevitable in the presence of matter and the Hermitian and anti-Hermitian components cannot be simultaneously diagonalized by unitary transformations for all matter densities. In this [...]
An interdisciplinary adventure in quantum materials and quantum devices
Speaker: Kin Chung Fong (Raytheon BBN, Harvard)Host: I. Borzenets
Quantum science and technology hold the promise to deepen our understanding of the universe and innovate groundbreaking technology. This poses a grand challenge to today’s scientists and engineers, unprecedented in the generations that came before us. Successfully achieving breakthroughs would require an interdisciplinary approach that leverages resources from various disciplines [...]
Non-geometric String Compactifications and the Swampland
Speaker: Muthusamy Rajaguru (Lehigh University)
The Swampland program attempts to classify Effective Field Theories based on their compatibility with Quantum Gravity. The criteria for compatibility are posed as conjectures for which there exist varying levels of evidence from explicit string compactifications. In this talk, I will discuss completed and ongoing work that is focused on [...]COHERENT Neutrino Program and the First Search for Neutrino-Induced Nuclear Fission
Speaker: Tyler Johnson (Duke University)Host: Doojin Kim
Over 50 years ago, it was predicted that it is possible to split an atom with a neutrino interaction, but there has never been a concerted experimental effort to confirm this phenomenon. The existence of this process would inform nuclear astrophysics, nuclear reactor monitoring and give a vantage into a [...]Stellar Abundances in the Milky Way and Their Implications for Nucleosynthesis
Speaker: Emily Griffith (University of Colorado Boulder)Host: Grace Olivier
Our understanding of the origin of the elements is grounded in observational abundance measurements and theoretical models of stellar explosions. The current era of big data from surveys such as APOGEE, GALAH, and Gaia allows us to study an unprecedented number of stars in abundance, velocity, and position space. With [...]

Speaker: Matteo Ippoliti (University of Texas at Austin)Host: Joaquin Rodriguez Nieva
High Dimension Operators of High Dimension CFTs
Speaker: Nathan Benjamin (California Institute of Technology)
I will discuss universal behavior of conformal field theory (CFT) data at high energies. In particular I will discuss universal formulas for both the entropy and the three-point-functions of local operators for d-dimensional CFT (d>2) as a function of energy and spin, using a technique called thermal effective field theory.
