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…
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…
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…
