Doppler shifted Hawking radiation from acoustic black holes in ultra-relativistic heavy-ion collisions
Sanatan Digal, Ajit M. Srivastava
In a hydrodynamic flow, with flow becoming supersonic at some point, the subsonic-supersonic boundary behaves as the horizon of a black hole. Possibility of detecting Hawking radia…
Correlated quantum shift vector of particle-hole excitations
Xu Yang, Ajit Srivastava, Justin C. W. Song
Excitons are a prime example of how electron interactions affect optical response and excitation. We demonstrate that, beyond its spectra, the bound nature of an exciton's electron…
Superradiance of Strongly Interacting Dipolar Excitons in Moiré Quantum Materials
Jan Kumlin, Ajit Srivastava, Thomas Pohl
Moiré lattices created in two-dimensional heterostructures exhibit rich many-body physics of interacting electrons and excitons and, at the same time, suggest promising optoelectr…
Signatures of collective photon emission and ferroelectric ordering of excitons near their Mott insulating state in a WSe/WS heterobilayer
Luka Matej Devenica, Zach Hadjri, Jan Kumlin +11
Spontaneous symmetry breaking, arising from the competition of interactions and quantum fluctuations, is fundamental to understanding ordered electronic phases. Although electrical…
Many-Body Photon Blockade and Quantum Light Generation from Cavity Quantum Materials
Benjamin Kass, Spenser Talkington, Ajit Srivastava +1
The strong coupling regime of photons and quantum materials inside optical cavities has emerged as a promising environment for manipulating states of matter with light. Here, in tu…
