Grassmannian Integrals as Matrix Models for Non-Compact Yangian Invariants
Nils Kanning, Yumi Ko, Matthias Staudacher
In the past years, there have been tremendous advances in the field of planar N=4 super Yang-Mills scattering amplitudes. At tree-level they were formulated as Grassmannian integra…
A criterion for the nature of the superconducting transition in strongly interacting field theories : Holographic approach
Ki-Seok Kim, Kyung Kiu Kim, Youngman Kim +1
It is beyond the present techniques based on perturbation theory to reveal the nature of phase transitions in strongly interacting field theories. Recently, the holographic approac…
Soft Wall Model in the Hadronic Medium
Chanyong Park, Do-Young Gwak, Bum-Hoon Lee +2
We study the holographic QCD in the hadronic medium by using the soft wall model. We discuss the Hawking-Page transition between Reissner-Nordström AdS black hole and thermal charg…
Density driven symmetry breaking and Butterfly effect in holographic superconductors
Youngman Kim, Yumi Ko, Sang-Jin Sin
We study the density driven symmetry breaking in holographic superconductors by considering the positive mass squared case. We show that even for the positive , a scalar conde…
The Entropy Function for the extremal Kerr-(anti-)de Sitter Black Holes
Jin-Ho Cho, Yumi Ko, Soonkeon Nam
Based on the entropy function formalism, we consider the extremal Kerr-(anti-)de Sitter black holes in 4-dimensions. Solving differential equations exactly, which are obtained by e…
Tests of Quantum Gravity via Generalized Uncertainty Principle
Yumi Ko, Sunggeun Lee, Soonkeon Nam
In this paper we propose a way of determining the subleading corrections to the Bekenstein-Hawking black hole entropy by considering a modified generalized uncertainty principle wi…
