Can a quantum circuit detect the Unruh effect?
Pravin Kumar Dahal, Timothy C. Ralph, William J. Munro +2
The Unruh effect predicts that an accelerating observer perceives the Minkowski vacuum as a thermal bath, yet direct detection remains experimentally inaccessible. Its timelike cou…
Collective Enhancement of Nuclear Excitation for a Nuclear Quantum Battery
Pravin Kumar Dahal, Kieran Hymas, Jack Muir +1
Current implementations of quantum batteries are constrained by limited energy density and short retention times associated with the electronic or molecular excitations. Here we pr…
Spatiotemporal entanglement of the vacuum
Pravin Kumar Dahal, Kieran Hymas
We demonstrate that the future and left Rindler wedges of Minkowski spacetime are entangled, leading to the Unruh effect. Similarly, the past and right Rindler wedges are also enta…
Horizon-bound objects: Kerr--Vaidya solutions
Pravin K. Dahal, Swayamsiddha Maharana, Fil Simovic +1
Kerr-Vaidya metrics are the simplest dynamical axially-symmetric solutions, all of which violate the null energy condition and thus are consistent with the formation of a trapped r…
