Quantum Mechanical Hamiltonians with Large Ground-State Degeneracy
Choonkyu Lee, Kimyeong Lee
Nonrelativistic Hamiltonians with large, even infinite, ground-state degeneracy are studied by connecting the degeneracy to the property of a Dirac operator. We then identify a spe…
Supersymmetric M5 Brane Theories on R x CP2
Hee-Cheol Kim, Kimyeong Lee
We propose 4 and 12 supersymmetric Yang-Mills-Chern-Simons theories on obtained by twisted moddings and dimensional reduction of the 6d (2,0)…
5-dim Superconformal Index with Enhanced En Global Symmetry
Hee-Cheol Kim, Sung-Soo Kim, Kimyeong Lee
The five-dimensional supersymmetric gauge theory with Sp(N) gauge group and SO(2N_f) flavor symmetry describes the physics on N D4-branes with D8-branes on to…
Superconformal Index with Duality Domain Wall
Dongmin Gang, Eunkyung Koh, Kimyeong Lee
We study a superconformal index for super Yang-Mills on with a half BPS duality domain wall inserted at the great two-sphere in . The index is ob…
Line Operator Index on S1 S3
Dongmin Gang, Eunkyung Koh, Kimyeong Lee
We derive a general formula of an index for N = 2 superconformal field theories on S1 \times S3 with insertions of BPS Wilson line or 't Hooft line operator at the north pole and t…
