Tree tensor networks and entanglement spectra

Iztok Pizorn, Frank Verstraete, Robert M. Konik

A tree tensor network variational method is proposed to simulate quantum many-body systems with global symmetries where the optimization is reduced to individual charge configurati…

Bose Hubbard model far from equilibrium

Iztok Pizorn

We study the nonequilibrium steady state of the Bose Hubbard model coupled to Lindblad reservoirs, using the density matrix renormalization group in operator space. We observe a tr…

Real time evolution at finite temperatures with operator space matrix product states

Iztok Pizorn, Viktor Eisler, Sabine Andergassen +1

We propose a method to simulate the real time evolution of one dimensional quantum many-body systems at finite temperature by expressing both the density matrices and the observabl…

Universality in entanglement of quasiparticle excitations

Iztok Pizorn

We show that the entanglement entropy of single quasiparticle excitations of one dimensional systems exceeds the ground state entanglement entropy for log(2), if the correlation le…

Time evolution of projected entangled pair states in the single layer picture

Iztok Pizorn, Ling Wang, Frank Verstraete

We propose an efficient algorithm for simulating quantum many-body systems in two spatial dimensions using projected entangled pair states. This is done by approximating the enviro…

Time-dependent variational principle for quantum lattices

Jutho Haegeman, J. Ignacio Cirac, Tobias J. Osborne +3

We develop a new algorithm based on the time-dependent variational principle applied to matrix product states to efficiently simulate the real- and imaginary time dynamics for infi…
