Supersymmetric zeta functions and determinants
Yu Nakayama, Tadashi Okazaki
We define supersymmetric zeta functions and supersymmetric determinants, which can reveal spectral properties complementary to those captured by the supersymmetric indices. They pl…
Conformal Bootstrap with Duality-Inspired Fusion Rule
Yu Nakayama, Toshiki Onagi
We present a systematic exploration of conformal field theories (CFTs) constrained by duality-inspired fusion rules using the conformal bootstrap. We classify the operator spectrum…
Revisiting the -theorem with the ANEC
Nanami Nakamura, Yu Nakayama, Ung Nguyen
The fundamental theorem in renormalization group flows in two dimensions is the -theorem, which dictates that the number of degrees of freedom must decrease monotonically along…
Non-Factorizing Interface in the Two-Dimensional Long-Range Ising Model
Dongsheng Ge, Yu Nakayama
The factorization proposal claims that the co-dimension one "pinning defect", on which a local relevant operator is integrated, factorizes the space into two halves in general conf…
To boost or not to boost, that's the question
Yu Nakayama
Or should we talk about dS/CFT correspondence or dS/SFT correspondence in cosmological correlators? In non-unitary field theories -- which are conjectured to be dual to cosmologica…
Parisi-Sourlas Supertranslation and Scale without Conformal symmetry
Yu Nakayama
Inspired by the possibility of emergent supersymmetry in critical random systems, we study a field theory model with a quartic potential of one superfield, possessing the Parisi-So…
