Landau theory, effective temperature, and tricritical phenomena in a holographic nonequilibrium steady state

Motohiro Kanazawa, Masataka Matsumoto, Shin Nakamura

We investigate the critical exponents at the current-driven tricritical point (TCP) associated with chiral symmetry breaking in a nonequilibrium steady state described by t…

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…

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…

Stark effect and dissociation of mesons in holographic conductor

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…

Electric-field driven nonequilibrium phase transitions in AdS/CFT

Daisuke Endo, Yuichi Fukazawa, Masataka Matsumoto +1

We study phase transitions and critical phenomena in nonequilibrium steady states controlled by an electric field. We employ the D3/D7 model in the presence of a charge density and…

Non-Hermitian quantum system generated from two coupled Sachdev-Ye-Kitaev models

Wenhe Cai, Sizheng Cao, Xian-Hui Ge +2

We show that a non-Hermitian two coupled Sachdev-Ye-Kitaev (SYK) model can provide thermodynamic structure equivalent to Hermitian two coupled SYK model. The energy spectrum, the e…

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…

Kink Crystalline Condensate and Multi-kink Solution in Holographic Superconductor

Masataka Matsumoto, Shin Nakamura, Ryosuke Yoshii

The theory of superconductivity can be divided into two groups depending on whether it has multi-kink solutions. For example, the BCS theory and the Gross-Neveu model have metastab…
