Thermal false vacuum decay near black holes is aspherical
D. S. Gorbunov, D. G. Levkov, V. E. Maslov
We study decay of a scalar field false vacuum near a (3+1)-dimensional Schwarzschild black hole equilibrated at Hawking temperature with the environment. Our scalar field model has…
Anyon Crystals and Hall Crystals in a Periodic Potential
Sayak Bhattacharjee, Julian May-Mann, Srinivas Raghu
We obtain integer and fractional quantum Hall crystals as ground states of a two-dimensional electron system subject to a strong perpendicular magnetic field and a periodic potenti…
Quantum turbulence in the many-body regime
Sayak Bhattacharjee, Mahendra K. Verma, Alexander V. Balatsky +1
We discuss phenomenology associated with turbulent hydrodynamics in quantum fluids from a condensed-matter perspective. We begin with weakly-interacting superfluids, often modeled…
Conserving relaxation-time approximation for electron-electron collisions
Sayak Bhattacharjee, Tatia Kiliptari, Dmitrii L. Maslov
We develop a conserving relaxation-time approximation (cRTA) based on an explicit energy-resolved projection onto the full space of collision invariants. Our cRTA retains the energ…
Tunable anyonic permeability across spin liquid junctions
Sayak Bhattacharjee, Soumya Sur, Adhip Agarwala
We introduce two classes of junctions in a toric code, a prototypical model of a quantum spin liquid, and study the nature of anyonic transport across them mediated…
Mesoscopic transport in a Chern mosaic
Sayak Bhattacharjee, Julian May-Mann, Yves H. Kwan +2
We analyze mesoscopic electronic transport in a Chern mosaic: a regular pattern of domains whose electronic bands carry differing local Chern numbers. An example platform where a C…
