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…
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…
A domain wall and chiral edge currents in holographic chiral phase transitions
Shuta Ishigaki, Masataka Matsumoto, Ryosuke Yoshii
We investigate spatially inhomogeneous solutions in a top-down holographic model: the D3/D7 model which provides a holographic description of the chiral phase transition for a fini…
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-…
First order phase transition in the D3-D7 model from the point of view of the fermionic spectral functions
Xian-Hui Ge, Shuta Ishigaki, Sang-Jin Sin +1
We consider the D3-D7 model and use the spectral function of a probe fermion on D7 to analyze the first order phase transition from the black-hole embedding phase to another black-…
Doped Holographic Superconductors in Gubser-Rocha model
Ziyi Zhao, Wenhe Cai, Shuta Ishigaki
We construct a doped holographic superconductor in the Gubser-Rocha model, and realize a superconducting dome in the middle of the temperature-doping phase diagram. It is worth not…

Shuta Ishigaki, Shunichiro Kinoshita, Masataka Matsumoto
We study the meson spectrum of the supersymmetric Yang-Mills theory with fundamental hypermultiplets for a finite electric field by using the D3/D7 mode…
Patchwork Conditions for Holographic Nonlinear Responses: A Computational Method for Electric Conductivity and Friction Coefficient
Shuta Ishigaki, Shin Nakamura, Kazuaki Takasan
We propose a new method to compute nonlinear transport coefficients in holography, such as nonlinear DC conductivity and nonlinear friction coefficient. The conventional method can…
Dynamical stability and filamentary instability in holographic conductors
Shuta Ishigaki, Shunichiro Kinoshita, Masataka Matsumoto
In this study, we analyze the dynamical stability of the D3-D7 model dual to a holographic conductor with a constant current under an external electric field. We particularly focus…

Shuta Ishigaki, Masataka Matsumoto
We investigate dispersion relation of Nambu-Goldstone modes in a dissipative system realized by the AdS/CFT correspondence. We employ the D3/D7 model which represents ${\cal N} = 4…
Mechanism for Negative Differential Conductivity in Holographic Conductors
Shuta Ishigaki, Shin Nakamura
We clarify the mechanism for negative differential conductivity in holographic conductors. Negative differential conductivity is a phenomenon in which the electric field decreses w…
