-deformed conformal field theories out of equilibrium
Marko Medenjak, Giuseppe Policastro, Takato Yoshimura
We consider the out-of-equilibrium transport in -deformed (1+1)-dimension conformal field theories (CFTs). The theories admit two disparate approaches, integrability and…
Thermal transport in -deformed conformal field theories: from integrability to holography
Marko Medenjak, Giuseppe Policastro, Takato Yoshimura
In this paper we consider the energy and momentum transport in (1+1)-dimension conformal field theories (CFTs) that are deformed by an irrelevant operator , using the int…
Collision rate ansatz for quantum integrable systems
Takato Yoshimura, Herbert Spohn
For quantum integrable systems the currents averaged with respect to a generalized Gibbs ensemble are revisited. An exact formula is known, which we call "collision rate ansatz". W…
Non-Hermitian quantum impurity systems in and out of equilibrium: noninteracting case
Takato Yoshimura, Kemal Bidzhiev, Hubert Saleur
We provide systematic analysis on a non-Hermitian PT -symmetric quantum impurity system both in and out of equilibrium, based on exact computations. In order to understand the inte…
