Phase Transition in JT Gravity and Deformation
Kyung Kiu Kim, Jong-Hyun Baek, Yunseok Seo
In this paper we study a black hole phase transition in a generalized JT gravity noticed in arXiv:2006.03494. We investigate the effect of the phase transition on the Euclidean geo…
Impurity Effect on Hysteric Magnetoconductance: Holographic Approach
Kyung Kiu Kim, Keun-Young Kim, Sang-Jin Sin +1
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 b…
Thermodynamics of Inhomogeneously Mass-deformed ABJM Model and Pressure Anisotropy
Seungjoon Hyun, Byoungjoon Ahn, Kyung Kiu Kim +2
In this paper we study the thermodynamics of black branes with a modulated complex scalar in the context of bulk and boundary theories. The modulation induces inhomogeneity to the…
AdS Q-Soliton and Inhomogeneously mass-deformed ABJM Model
Byoungjoon Ahn, Seungjoon Hyun, Kyung Kiu Kim +2
We study dual geometries to a deformed ABJM model with spatially dependent source functions at finite temperature. These source functions are proportional to the mass function $m(x…
Building Magnetic Hysteresis in Holography
Kyung Kiu Kim, Keun-Young Kim, Yunseok Seo +1
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 l…
Expanding Universe and Dynamical Compactification Using Yang-Mills Instantons
Kyung Kiu Kim, Seoktae Koh, Hyun Seok Yang
We consider an eight-dimensional Einstein-Yang-Mills theory to explore whether Yang-Mills instantons formed in extra dimensions can induce the dynamical instability of our four-dim…
