Constructing an entangled Unruh Otto engine and its efficiency
Journal of High Energy Physics, 2022 Uniformly accelerated frame mimics a thermal bath whose temperature is proportional to the proper acceleration. Using this phenomenon we give a detailed construction of an Otto cycle between two energy eigenstates of a system, consists of two entangled ...

Beyond the Boltzmann equation for weakly coupled quantum fields
Journal of High Energy PhysicsWe study the kinetic theory of a weakly interacting quantum field. Assuming a state that is close to homogeneous and stationary, we derive a closed kinetic equation for the rate of change of the occupation numbers, perturbatively in the coupling.

Decoherence in an interacting quantum field theory: Thermal case
, 2011 We study the decoherence of a renormalized quantum field theoretical system. We consider our novel correlator approach to decoherence where entropy is generated by neglecting observationally inaccessible correlators. Using out-of-equilibrium field theory

OTOC and quamtum chaos of interacting scalar fields
Journal of High Energy PhysicsDiscretizing the λϕ 4 scalar field theory on a lattice yields a system of coupled anharmonic oscillators with quadratic and quartic potentials. We begin by analyzing the two coupled oscillators in the second quantization method to derive several analytic

Causal and stable superfluid hydrodynamics
Journal of High Energy PhysicsWe investigate the linearized stability and causality properties of relativistic viscous superfluid hydrodynamics. The Landau-Lifshitz-Clark-Putterman formulation for the theory of relativistic viscous superfluids suffers from the same instability and ...

Finite-temperature effective boundary theory of the quantized thermal Hall effect
New Journal of Physics, 2016 A finite-temperature effective free energy of the boundary of a quantized thermal Hall system is derived microscopically from the bulk two-dimensional Dirac fermion coupled with a gravitational field.
