Quantum many-body simulations using Gaussian phase-space representations
P. D. Drummond, P. Deuar, J. F. Corney
Phase-space representations are of increasing importance as a viable and successful means to study exponentially complex quantum many-body systems from first principles. This revie…
Gaussian operator bases for correlated fermions
J. F. Corney, P. D. Drummond
We formulate a general multi-mode Gaussian operator basis for fermions, to enable a positive phase-space representation of correlated Fermi states. The Gaussian basis extends exist…
Gaussian phase-space representations for fermions
J. F. Corney, P. D. Drummond
We introduce a positive phase-space representation for fermions, using the most general possible multi-mode Gaussian operator basis. The representation generalizes previous bosonic…
Gaussian quantum Monte Carlo methods for fermions
J. F. Corney, P. D. Drummond
We introduce a new class of quantum Monte Carlo methods, based on a Gaussian quantum operator representation of fermionic states. The methods enable first-principles dynamical or e…
Quantum dynamics with stochastic gauge simulations
P. D. Drummond, P. Deuar
The general idea of a stochastic gauge representation is introduced and compared with more traditional phase-space expansions, like the Wigner expansion. Stochastic gauges can be u…
