    Efficient dynamical simulation of strongly correlated one-dimensional quantum systems by Clark, SR, Jaksch, D

    Published 2006
    “…For an important class of one-dimensional (11)) systems dynamical simulations have become possible since the advent of the time-evolving block decimation (TEBD) algorithm. We study the computational properties of TEBD using the Bose-Hubbard model (BHM) as a test-bed. …”

    Directed percolation in nonunitary quantum cellular automata by Ramil Nigmatullin, Elisabeth Wagner, Gavin K. Brennen

    Published 2021-12-01
    “…In this work, we construct a nonunitary quantum CA that generalizes the Domany-Kinzel CA and study the resulting dynamical evolution using numerical simulations using the tensor network infinite time-evolving block decimation (iTEBD) algorithm. We demonstrate that the system undergoes the absorbing/percolating phase transition and that the addition of the Hamiltonian generates coherences, which are a distinct feature of quantum dynamics. …”

    Measurement-induced phase transition: A case study in the nonintegrable model by density-matrix renormalization group calculations by Qicheng Tang, W. Zhu

    Published 2020-01-01
    “…As a concrete example, a one-dimensional Bose-Hubbard model is simulated by the matrix product state and time-evolving block decimation. We map out a global phase diagram in terms of the measurement rate in spatial space and time domain, which demonstrates a volume-to-area law entanglement phase transition. …”

    Dissipation-induced correlations in one-dimensional bosonic systems by Kiffner, M, Hartmann, M

    Published 2011
    “…We consider dissipative and conservative two-particle interactions, and integrate the master equation describing the system dynamics via a time-evolving block-decimation (TEBD) algorithm. Our numerical simulations directly apply to stationary-light polaritons in systems where atoms and photons are confined to the hollow core of a photonic crystal fibre. …”

    Heat transport in the XXZ spin chain: from ballistic to diffusive regimes and dephasing enhancement by Mendoza-Arenas, J, Al-Assam, S, Clark, SR, Jaksch, D

    Published 2013
    “…The non-equilibrium steady state of the chain is obtained by simulating its evolution under the corresponding Lindblad master equation, using the time evolving block decimation method. In the absence of dephasing, the heat transport is ballistic for weak interactions, while being diffusive in the strongly interacting regime, as evidenced by the heat current scaling with the system size. …”

    Transport in out-of-equilibrium XXZ chains: Exact profiles of charges and currents by Bertini, B, Collura, M, De Nardis, J, Fagotti, M

    Published 2016

As a corollary, we unveil an exact expression for the expectation values of the charge currents in a generic stationary state.…”

    Tensor network simulation of chains of non-Markovian open quantum systems by Gerald E. Fux, Dainius Kilda, Brendon W. Lovett, Jonathan Keeling

    Published 2023-08-01
    “…The method combines the process tensor formalism for general (possibly non-Markovian) open quantum systems with time-evolving block decimation for one-dimensional chains. It systematically reduces the numerical complexity originating from system-environment correlations before integrating them into the full many-body problem, making a wide range of applications numerically feasible. …”
