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…
