Abstract

Charge conjugation (C), Parity (P), and Time-reversal (T) are three discrete transformations that act on particles and fields. C-P-T-fractionalization is the discrete group generated by C, P, T, and the Fermion parity F. In this talk, I will determine the C-P-T-fractionalization for spin 1/2 Lorentz spinors in all dimensions and explain the relations between the C-P-T-fractionalization in different dimensions. This is my joint work in progress with Juven Wang and Prof. Shing-Tung Yau.

  • On-shell action and Entanglement entropy of T$\bar{\text{T}}$-deformed Holographic CFTs

    AbstractIn this work, we study the holographic dual of the \ttbar deformation following the mixed boundary condition proposal. We point out that a boundary term should be included in the gravity action in the holographic dictionary. We show some evidence that this boundary term will modify the RT formula. In particular, we consider the deformed CFT defined on a sphere (dS) or AdS background and...
