Abstract In this work, we study the end-of-the-world (EOW) branes anchored to the boundaries of BCFT $${}_2$$ 2 dual to the BTZ black hole. First, we explore the thermodynamics of the boundary system consisting of the conformal boundary and two EOW b

Abstract In this work, we study Metal-Insulator transition in a holographic model containing an interaction between the order parameter and charge-carrier density. It turns out that the impurity density of this model can drive the phase transition wh

Abstract In this paper we study a hysteric phase transition from weak localization phase to hysteric magnetoconductance phase using gauge/gravity duality. This hysteric phase is triggered by a spontaneous magnetization related to ℤ2 symmetry and ti

Abstract We show that we can realize the surface state together with the bulk state of various types of topological matters in holographic context, by considering various types of Lorentz symmetry breaking. The fermion spectral functions in the prese

Abstract We consider the magneto-transports of quantum matters doped with magnetic impurities near the quantum critical points (QCP). For this, we first find new black hole solution with hyper-scaling violation which is dual to such system. By consid

Abstract It is often said that interactions destroy the particle nature of excitations. We report that, in holographic theory adding interaction term can create a new quasi particle spectrum, on the contrary. We show this by calculating the optical c

Abstract We study the spontaneous magnetization and the magnetic hysteresis using the gauge/gravity duality. We first propose a novel and general formula to compute the magnetization in a large class of holographic models. By using this formula, we c

Abstract We show that the Mott transition can be realized in a holographic model of a fermion with bulk mass, m, and a dipole interaction of coupling strength p. The phase diagram contains gapless, pseudo-gap and gapped phases and the first one can b

Abstract Recent discovery of transport anomaly in graphene demonstrated that a system known to be weakly interacting may become strongly correlated if system parameter (s) can be tuned such that fermi surface is sufficiently small. We study the stron

Gauge/Gravity duality as a theory of matter needs a systematic way to characterise a system. We suggest a ‘dimensional lifting’ of the least irrelevant interaction to the bulk theory. As an example, we consider the spin–orbit interaction, which
