On Time-Evolution in Quantum Gravity
Lasha Berezhiani, Gia Dvali, Otari Sakhelashvili
We derive an explicit BRST-exact operator identity for the bulk Hamiltonian in quantum gravity, working within a BRST-invariant quantization of General Relativity, treated as a low…
Coherence and Quantum Stability of Relativistic Superfluid States
Lasha Berezhiani, Giordano Cintia, Giacomo Contri
We analyze the quantum dynamics of a relativistic homogeneous superfluid in a complex scalar field theory. Unlike zero-charge condensates, which undergo quantum evaporation due to…
Superfluid Dark Matter
Lasha Berezhiani, Giordano Cintia, Valerio De Luca +1
The superfluid dark matter model offers an elegant solution to reconcile discrepancies between the predictions of the cold dark matter paradigm and observations on galactic scales.…
