Generalized thermalization for integrable system under quantum quench
Sushruth Muralidharan, Kinjalk Lochan, S. Shankaranarayanan
We investigate equilibration and generalized thermalization of the quantum Harmonic chain under local quantum quench. The quench action we consider is connecting two disjoint harmo…
Quantum leaps of black holes: Magnifying glasses of quantum gravity
Sumanta Chakraborty, Kinjalk Lochan
We show using simple arguments, that the conceptual triad of a {\it classical} black hole, semi-classical Hawking emission and geometry quantization is inherently, mutually incompa…
Information retrieval from black holes
Kinjalk Lochan, Sumanta Chakraborty, T. Padmanabhan
It is generally believed that, when matter collapses to form a black hole, the complete information about the initial state of the matter cannot be retrieved by future asymptotic o…
