Tensor Network Formulation of -Symmetric Quantum Field Theory
Yasuyuki Hatsuda, Kengo Kikuchi
We develop a non-perturbative analytic tensor network formulation of -symmetric scalar field theories defined on complex integration contours. Applying this formulati…
Exact WKB and Quantum Periods for Extremal Black Hole Quasinormal Modes
Yasuyuki Hatsuda, Tomohito Shiga
We apply exact WKB analysis to the spectral problem arising in black hole perturbation theory. The boundary conditions for quasinormal modes lead to exact quantization conditions f…
Quarter-indices for basic ortho-symplectic corners
Yasuyuki Hatsuda, Tadashi Okazaki
We study supersymmetric quarter-indices for corner configurations in 4d super Yang-Mills theory with orthogonal and symplectic gauge groups. For the basic Y-junctio…
Interface line operators in SYM theories and supersymmetric indices
Yasuyuki Hatsuda, Tadashi Okazaki
We study configurations of two super Yang-Mills theories of unitary gauge groups connected by the BPS interfaces involving line operators. We find strong evidence o…
Non-perturbative effects in JT gravity from KdV equations
Yasuyuki Hatsuda, Takaki Matsumoto, Kazumi Okuyama
It is well-known that the partition function of the Jackiw-Teitelboim (JT) gravity is obtained by an integral transformation of volumes of moduli spaces for Riemann surfaces, also…
S-duality of boundary lines in SYM theories and supersymmetric indices
Yasuyuki Hatsuda, Tadashi Okazaki
We analyze the supersymmetric defect indices of super Yang Mills theories which are simultaneously decorated by the BPS line operators and the boundary conditions.…
