Bootstrapping the effect of the twist operator in the D1D5 CFT
Bin Guo, Shaun Hampton
In the D1D5 CFT the twist operator of order 2 can twist together two copies in the untwisted sector into a single joined copy in the twisted sector. Traditionally, this effect is c…
Thermalization in the D1D5 CFT
Shaun Hampton, Samir D. Mathur
It is generally agreed that black hole formation in gravity corresponds to thermalization in the dual CFT. It is sometimes argued that if the CFT evolution shows evidence of large…
Quantum Quench in Matrix Model and Emergent Space-times
Sumit R. Das, Shaun Hampton, Sinong Liu
We consider quantum quench in large-N singlet sector quantum mechanics of a single hermitian matrix in the double scaling limit. The time dependent parameter is the self-coupling o…
Understanding Black Hole Formation in String Theory
Shaun Hampton
The strongly coupled dynamics of black hole formation in bulk AdS is conjectured to be dual to the thermalization of a weakly interacting CFT on the boundary for low which, for…
Quantum Quench in Non-relativistic Fermionic Field Theory: Harmonic traps and 2d String Theory
Sumit R. Das, Shaun Hampton, Sinong Liu
We investigate a class of exactly solvable quantum quench protocols with a finite quench rate in systems of one dimensional non-relativistic fermions in external harmonic oscillato…
Lifting of D1-D5-P states
Shaun Hampton, Samir D. Mathur, Ida G. Zadeh
We consider states of the D1-D5 CFT where only the left-moving sector is excited. As we deform away from the orbifold point, some of these states will remain BPS while others can `…
