Irregular Conformal States and Spectral Curve: Irregular Matrix Model Approach
Chaiho Rim
We present recent developments of irregular conformal conformal states. Irregular vertex operators and their adjoint in a new formalism are used to define the irregular conformal s…
Green-Schwarz superstring on doubled-yet-gauged spacetime
Jeong-Hyuck Park
We construct a world-sheet action for Green-Schwarz superstring in terms of doubled-yet-gauged spacetime coordinates. For an arbitrarily curved NS-NS background, the action possess…
Emergent Spacetime for Quantum Gravity
Hyun Seok Yang
We emphasize that noncommutative (NC) spacetime necessarily implies emergent spacetime if spacetime at microscopic scales should be viewed as NC. In order to understand NC spacetim…
Matrix models from localization of five-dimensional supersymmetric noncommutative U(1) gauge theory
Bum-Hoon Lee, Daeho Ro, Hyun Seok Yang
We study localization of five-dimensional supersymmetric gauge theory on where is a noncommutative (NC) plane. The…
Super-spectral curve of irregular conformal blocks
Dimitri Polyakov, Chaiho Rim
We use super-spectral curve to investigate irregular conformal states of integer and half-odd integer rank. The spectral curve is the loop equation of supersymmetrized irregular ma…
Determination of the thickness and orientation of few-layer tungsten ditelluride using polarized Raman spectroscopy
Minjung Kim, Songhee Han, Jung Hwa Kim +3
Orthorhombic tungsten ditelluride (WTe2), with a distorted 1T structure, exhibits a large magnetoresistance that depends on the orientation, and its electrical characteristics chan…
