Finite- BMN index across all vacuum sectors
Chi-Ming Chang, Sarthak Duary, Kangning Liu
We compute the finite- Witten index of BMN matrix quantum mechanics after summing over all partition-labeled supersymmetric vacuum sectors. Starting from the unitary-matrix inte…
Mass-Flow Invariance of -Cohomology in BMN Matrix Quantum Mechanics
Chi-Ming Chang, Zhengyuan Du, Sarthak Duary +2
We study the dependence of the dynamical supercharges of BMN matrix quantum mechanics on the mass parameter . Taking the -derivative at fixed canonical matrix variables, we…
-deformation as a Riemann bilinear dressing
Kangning Liu
We propose a reformulation of the conformal perturbation theory of the correlation functions in -deformed CFTs as a dressing on the deformed operators, that matches both…
Corrections of an elliptic block in the NS sector
Kangning Liu
We propose a correction to one of the elliptic blocks in the NS sector of 2d superconformal field theories. We analyze the 4-point block in the pillow geometry to…
super complex Liouville string
Zhengyuan Du, Kangning Liu, Zhe-fei Yu
We study the (type 0B) supersymmetric complex Liouville string (), a supersymmetric extension of the bosonic complex Liouville string (…
Wiggling boundary and corner edge modes in JT gravity with defects
Kang Liu, Shoupan Liu, Xiao-Mei Kuang
We study the gravitational edge modes (GrEMs) and gauge edge modes (GaEMs) in Jackiw-Teitelboim (JT) gravity on a wiggling boundary. The wiggling effect manifests as a series of sp…
