Fate of "Space-like singularities" in Matrix Model

Sumit R. Das, Shaun D. Hampton, Sinong Liu +1

A class of time dependent backgrounds in two dimensional String Theory leads to superluminal Liouville walls on the worldsheet. In the dual double scaled matrix model these b…

Superluminal Liouville walls in 2d String Theory and space-like singularities

Sumit R. Das, Shaun D. Hampton, Sinong Liu

An interesting class of time dependent backgrounds in dimensional string theory involves worldsheet Liouville walls which move in (target space) time. When a parameter in suc…

Spread Complexity and Topological Transitions in the Kitaev Chain

Pawel Caputa, Nitin Gupta, S. Shajidul Haque +3

A number of recent works have argued that quantum complexity, a well-known concept in computer science that has re-emerged recently in the context of the physics of black holes, ma…

Quantum complexity and topological phases of matter

Pawel Caputa, Sinong Liu

In this work, we find that the complexity of quantum many-body states, defined as a spread in the Krylov basis, may serve as a new probe that distinguishes topological phases of ma…

Entanglement Entropy and Phase Space Density: Lowest Landau Levels and 1/2 BPS states

Sumit R. Das, Shaun Hampton, Sinong Liu

We consider the entanglement entropy of an arbitrary subregion in a system of non-relativistic fermions in dimensions in Lowest Landau Level (LLL) states. Using the conne…

Gauge Invariant Target Space Entanglement in D-Brane Holography

Sumit R. Das, Anurag Kaushal, Sinong Liu +2

It has been suggested in arXiv:2004.00613 that in Dp-brane holography, entanglement in the target space of the D-brane Yang-Mills theory provides a precise notion of bulk entanglem…
