Separating the Role of Mixing‐Entropy on the Dynamics of Glass‐Forming Liquids
Advanced Science, EarlyView.This research innovates by distinguishing entropy’s impact from enthalpy in materials through micro‐alloying. It finds liquid fragility decreases with minimal alloying content or increased element diversity. This clarifies entropy’s role and supports the entropy‐driven glass transition, guiding new material design.

Boson localization and the superfluid-insulator transition.
Physical Review B (Condensed Matter), 1989 The phase diagrams and phase transitions of bosons with short-ranged repulsive interactions moving in periodic and/or random external potentials at zero temperature are investigated with emphasis on the superfluid-insulator transition induced by varying ...

Ultralight Boson Dark Matter and Event Horizon Telescope Observations of M87^{*}. [PDF]
Physical Review Letters, 2019 The initial data from the Event Horizon Telescope (EHT) on M87^{*}, the supermassive black hole at the center of the M87 Galaxy, provide direct observational information on its mass, spin, and accretion disk properties.

Key Topics in Nuclear Structure, 2005 We derive a boson Hamiltonian from a Nuclear Hamiltonian whose potential is expanded in pairing multipoles and determine the fermion-boson mapping of operators. We use a new method of bosonization based on the evaluation of the partition function restricted to the bosonic composites of interest.

Boson-fermion pairing in a boson-fermion environment [PDF]
Physical Review A, 2005 Propagation of a Boson-Fermion (B-F) pair in a B-F environment is considered. The possibility of formation of stable strongly correlated B-F pairs, embedded in the continuum, is pointed out. The new Fermi gas of correlated B-F pairs shows a strongly modified Fermi surface.

Quantum Anomalies in Condensed Matter
Advanced Physics Research, EarlyView.Quantum materials provide a fertile ground in which to test and realize quantum anomalies predicted by quantum field theory. Quantum anomalies need to be canceled globally, however, quantum states with a quantum anomaly can exist at the boundary of topological materials.

Classical and quantum gravity, 2018 We present new, fully nonlinear numerical solutions to the static, spherically symmetric Einstein–Klein–Gordon system for a collection of an arbitrary odd number N of complex scalar fields with an internal symmetry and no self-interactions.

Anomalies and Bosonization [PDF]
Communications in Mathematical Physics, 2020 Recently, general methods of bosonization beyond 1+1 dimensions have been developed. In this article, we review these bosonizations and extend them to the case with boundary conditions. In particular, we study the case when the bulk theory is a $G$-symmetry protected topological phase and the boundary theory has a $G$ 't Hooft anomaly.
