Dual Gauge Theory for Two Dimensional Superfluid Turbulence
Tobias Helbig, Sayak Bhattacharjee, Srinivas Raghu
We describe turbulent hydrodynamics of superfluids in two spatial dimensions via the dynamics of point-like vortices coupled to an emergent 2+1 dimensional gauge field. The…
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…
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…
Composite boson theory of Hall crystals and their transitions to Wigner crystals
Julian May-Mann, Sayak Bhattacharjee, Srinivas Raghu
We consider the crystallization of a two-dimensional electron system in a perpendicular magnetic field using composite boson theory. There are three possible states to consider: th…
