Lee-Huang-Yang dynamics emergent from a direct Wigner representation
King Lun Ng, Maciej Bartłomiej Kruk, Piotr Deuar
We demonstrate how the beyond-mean-field Lee-Huang-Yang (LHY) corrections and its related physics can be naturally incorporated into the representation of an ultracold Bose gas usi…
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…
Nonlocal pair correlations in a higher-order Bose gas soliton
King Lun Ng, Bogdan Opanchuk, Margaret D. Reid +1
The truncated Wigner and positive-P phase-space representations are used to study the dynamics of a one-dimensional Bose gas. This allows calculations of the breathing quantum dyna…
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…
Decoherence of Einstein-Podolsky-Rosen steering
L. Rosales-Zárate, R. Y. Teh, S. Kiesewetter +3
We consider two systems A and B that share Einstein-Podolsky-Rosen (EPR) steering correlations and study how these correlations will decay, when each of the systems are independent…
