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…
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…
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…
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…
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…
Quantum -theory of Lagrangian Grassmannian via parabolic Peterson isomorphism
Takeshi Ikeda, Takafumi Kouno, Yusuke Nakayama +1
We study Schubert calculus in the torus-equivariant quantum -ring of the Lagrangian Grassmannian . Our main tool is the -theoretic Peterson map due to Kato. T…
Who told you magnetization is a vector in dimensions?
Yu Nakayama
But if you treat it as a two-form, you get three nontrivial renormalization group fixed points! Which becomes the Heisenberg fixed point in three dimensions? Motivated by this ques…
Generalized Free Conformal Field Theories at Infinite Temperature -- In memory of Iwasaki-sensei
Yu Nakayama
Can space-time symmetries such as Lorentz, dilatation, or conformal symmetry be recovered at infinite temperature? To address this question, we study correlation functions of gener…
Central Extension of Scaling Poincaré Algebra
Yu Nakayama
We discuss the possibility of a central extension of the Poincaré algebra and the scaling Poincaré algebra. In more than two space-time dimensions, all the central extensions are t…
