A combinatorial proof of a Weyl type formula for hook Schur polynomials

Jae-Hoon Kwon

In this paper, we present a simple combinatorial proof of a Weyl type formula for hook Schur polynomials, which has been obtained by using a Kostant type cohomology formula for $\f…

From static to evolving geometries -- R-charged hydrodynamics from supergravity

Dongsu Bak, Romuald A. Janik

We show that one can obtain asymptotic evolving boost-invariant geometries in a simple manner from the corresponding static solutions. We exhibit the procedure in the case of a sup…

Infrared Hall conductivity of Na $_{0.7}$ CoO $_{2}$

E. J. Choi, S. H. Jung, J. H. Noh +5

We report infrared Hall conductivity $σ_{x y} (ω)$ of Na $_{0.7}$ CoO $_{2}$ thin films determined from Faraday rotation angle $θ_{F}$ measurements. $σ_{x y} (ω)$ exhibits two types of hole…

Twist and teleportation analogy of the black hole final state

Doyeol Ahn, M. S. Kim

Mathematical connection between the quantum teleportation, the most unique feature of quantum information processing, and the black hole final state is studied taking into account…

Supersymmetric Q-Lumps in the Grassmannian nonlinear sigma models

Dongsu Bak, Sang-Ok Hahn, Joohan Lee +1

We construct the N=2 supersymmetric Grassmannian nonlinear sigma model for the massless case and extend it to massive N=2 model by adding an appropriate superpotential. We then stu…

Epidemic Dynamics of Interacting Two Particle Species on Scale-free Networks

Yong-Yeol Ahn, Naoki Masuda, Hawoong Jeong +1

We study the non-equilibrium phase transition in a model for epidemic spreading on scale-free networks. The model consists of two particle species $A$ and $B$ , and the coupling bet…
