The iTEBD algorithm beyond unitary evolution
Roman Orus, Guifre Vidal
The infinite time-evolving block decimation (iTEBD) algorithm [Phys. Rev. Lett. 98, 070201 (2007)] allows to simulate unitary evolution and to compute the ground state of one-dimen…
Universal geometric entanglement close to quantum phase transitions
Roman Orus
Under successive Renormalization Group transformations applied to a quantum state of finite correlation length , there is typically a loss of entanglement after each ite…
Ground state fidelity from tensor network representations
Huan-Qiang Zhou, Roman Orus, Guifre Vidal
For any D-dimensional quantum lattice system, the fidelity between two ground state many-body wave functions is mapped onto the partition function of a D-dimensional classical stat…
Classical simulation of infinite-size quantum lattice systems in two spatial dimensions
J. Jordan, R. Orus, G. Vidal +2
We present an algorithm to simulate two-dimensional quantum lattice systems in the thermodynamic limit. Our approach builds on the {\em projected entangled-pair state} algorithm fo…
