On Intersecting Conformal Defects
Tom Shachar
We study the physics of 2 and 3 mutually intersecting conformal defects forming wedges and corners in general dimension. For 2 defects we derive the beta function of the edge inter…
The defect b-theorem under bulk RG flows
Tom Shachar, Ritam Sinha, Michael Smolkin
It is known that for RG flows confined to a two-dimensional defect, where the bulk maintains its conformal nature, the coefficient of the Euler density in the defect's Weyl anomaly…
Linear response of entanglement entropy to in massive QFTs
Shachar Ashkenazi, Soumangsu Chakraborty, Zhanyu Ma +1
We compute the leading correction to entanglement entropy in deformed massive QFTs. We show that both for massive scalar and Dirac fermion, the leading order correction…
RG flows on two-dimensional spherical defects
Tom Shachar, Ritam Sinha, Michael Smolkin
We study two-dimensional spherical defects in d-dimensional Conformal Field Theories. We argue that the Renormalization Group (RG) flows on such defects admit the existence of a de…
On quantum quenches at one loop
Mikhail Goykhman, Tom Shachar, Michael Smolkin
We study global quenches in a number of interacting quantum field theory models away from the conformal regime. We conduct a perturbative renormalization at one-loop level and trac…
On fast quenches and spinning correlators
Mikhail Goykhman, Tom Shachar, Michael Smolkin
We study global quantum quenches in a continuous field theoretic system with UV fixed point. Assuming that the characteristic inverse time scale of the smooth quench is much larger…
