A time-dependent variational principle for dissipative dynamics
Christina V. Kraus, Tobias J. Osborne
We extend the time-dependent variational principle to the setting of dissipative dynamics. This provides a locally optimal (in time) approximation to the dynamics of any Lindblad e…

Generalized Hartree Fock Theory for Dispersion Relations of Interacting Fermionic Lattice Systems
Christina V. Kraus, Tobias J. Osborne
We study the variational solution of generic interacting fermionic lattice systems using fermionic Gaussian states and show that the process of "gaussification", leading to a nonli…
