Four inequivalent paths to Thermality in Minkowski spacetime
Rakesh K Jha, Akhil U Nair, Prasant Samantray +1
We investigate thermal behaviour in quantum fields by analysing a hierarchy of null-shifted Rindler wedges in Minkowski spacetime. Starting from the Minkowski vacuum restricted to…
Selective Thermalization, Chiral Excitations, and a Case of Quantum Hair in the Presence of Event Horizons
Akhil U Nair, Rakesh K. Jha, Prasant Samantray +1
The Unruh effect is a well-understood phenomenon, where one considers a vacuum state of a quantum field in Minkowski spacetime, which appears to be thermally populated for a unifor…
Schwinger Effect in Compact Space
Prasant Samantray, Suprit Singh
We consider a theory of scalar QED on a spatially compact 1+1-dimensional spacetime. By considering a constant electric field pointing down the compact dimension, we compute the qu…
A Bound on Thermal Relativistic Correlators at Large Spacelike Momenta
Souvik Banerjee, Kyriakos Papadodimas, Suvrat Raju +2
We consider thermal Wightman correlators in a relativistic quantum field theory in the limit where the spatial momenta of the insertions become large while their frequencies stay f…
Schwinger Pair Production in Hot Anti-de Sitter Space
Prasant Samantray, Suprit Singh
We consider particle production in dimensional thermal Anti-de Sitter space under the influence of a constant electric field. The vacuum-persistence amplitude is given by a n…
Phase Transitions of a (Super) Quantum Mechanical Matrix Model with a Chemical Potential
Takehiro Azuma, Pallab Basu, Prasant Samantray
In this paper, we study the finite-temperature matrix quantum mechanics with chemical potential term linear in the single trace of U(N) matrices, via Monte Carlo simulation. In the…
