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…

Holographic superconductor model represents various inhomogeneous solutions with homogeneous sources. In this paper, we study inhomogeneous structures in the presence of the homoge…
Nambu-Goldstone modes in non-equilibrium systems from AdS/CFT correspondence
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 ${\cal N} = 4…
Current-driven tricritical point in large- gauge theory
Takuya Imaizumi, Masataka Matsumoto, Shin Nakamura
We discover a new tricritical point realized only in non-equilibrium steady states, using the AdS/CFT correspondence. Our system is a (3+1)-dimensional strongly-coupled large-$N_{c…
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…

Masataka Matsumoto, Shin Nakamura
We study critical phenomena of nonequilibrium phase transitions by using the AdS/CFT correspondence. Our system consists of charged particles interacting with a heat bath of neutra…
