Nonequilibrium Andreev transport at the QGP-2SC interface
Tingyu Zhang, Honoka Hoshino, Hiroyuki Tajima +2
We discuss a nonequilibrium Andreev reflection at an interface between quark-gluon plasma (QGP) and two-flavor color superconducting (2SC) quark matter. Based on the Schwinger-Keld…
Noise spectroscopy of two-body loss as a probe of dynamical bulk viscosity in ultracold atomic gases
Tingyu Zhang, Hiroyuki Tajima, Takeo Kato
We show that the correlated noise of the two-body loss current provides access to the dynamical bulk viscosity in weakly dissipative quantum gases. Starting from the Lindblad equat…
Josephson effects in an interaction-asymmetric junction across the BCS-BEC crossover
Tingyu Zhang, Hiroyuki Tajima
We theoretically study the Josephson effect in ultracold Fermi gases, where the two sides of the Josephson junction are independently tuned to different regions of the Bardeen-Coop…
Local decay estimates for the bi-Laplacian Nonautonomous Schrödinger equation
Jiayan Wu, Ting Zhang, Ruze Zhou
In this paper, we establish local decay estimates for the bi-Laplacian Schrödinger equation with time-dependent (in particular, quasi-periodic) potentials in spatial dimension $n\…
Schwinger-Keldysh approach to tunneling transport at a hadron-quark interface
Tingyu Zhang, Hiroyuki Tajima, Motoi Tachibana
We theoretically discuss quantum tunneling transport and frictions at a hadron-quark matter interface based on the Schwinger-Keldysh approach combined with the tunneling Hamiltonia…
Supersymmetry-like tunneling current noise as a probe of Goldstino excitation in a Bose-Fermi mixture
Tingyu Zhang
The Goldstino, which is a fermionic Nambu-Goldstone mode, has been predicted in a Bose-Fermi mixture when the supersymmetry is broken. To detect this excitation mode, we theoretica…
