Quantum Mpemba effect in holography
Xian-Hui Ge, Shuta Ishigaki, Yu-Qi Lei +1
We investigate the quantum Mpemba effect in a holographic superfluid, in which states with stronger initial symmetry breaking relax faster toward the symmetry-restored equilibrium.…
Scheme dependence and instability of double-trace deformations for gauge fields in AdS
Shuta Ishigaki, Masataka Matsumoto
In holography, double-trace deformations provide a general framework for deforming boundary field theories. In particular, they can be utilized to introduce dynamical gauge fields…
Dynamical Stability and Critical Exponents of the Neutral (S-type) Gubser-Rocha Model with Momentum Dissipation
Shuta Ishigaki
The (S-type) Gubser-Rocha model is a holographic model that shows the linear dependence of the entropy density on the temperature. With an appropriate choice of the boundary action…
Dependence of the critical temperature and disorder in holographic superconductors on superfluid density
Zhenguo Wang, Xian-Hui Ge, Shuta Ishigaki
Recent experiments strongly indicate deep connections between transports of strange metal and high superconductors. For instance, it is known that the dependence of the zero-…
Thermodynamics, magnetic properties, and global symmetry breaking of the S-type Gubser-Rocha model
Shuta Ishigaki, Zhaojie Xu
We study an explicit formula for the thermodynamic potential of the AdS dyonic black brane solution with an axio-dilaton hair, which was discovered in an extension of the d…
