The fate of the false vacuum: Finite temperature, entropy and topological phase in quantum simulations of the early universe
King Lun Ng, Bogdan Opanchuk, Manushan Thenabadu +2
Despite being at the heart of the theory of the "Big Bang" and cosmic inflation, the quantum field theory prediction of false vacuum tunneling has not been tested. To address the e…

Phase-space representations of thermal Bose-Einstein condensates
King Ng, Rodney Polkinghorne, Bogdan Opanchuk +1
Phase-space methods allow one to go beyond the mean-field approximation to simulate the quantum dynamics of interacting fields. Here, we obtain a technique for initializing either…
