Persistent oscillation of a Cooper-pair condensate of topological defects in a nonintegrable quantum Ising chain
Francis A. Bayocboc, Jacek Dziarmaga, Marek M. Rams +1
We identify persistent oscillations in a nonintegrable quantum Ising chain. In the integrable chain with nearest-neighbor interactions, the nature, origin, and decay of post-transi…
Inhomogeneous adiabatic preparation of a quantum critical ground state in two dimensions
Ihor Sokolov, Francis A. Bayocboc, Marek M. Rams +1
Adiabatic preparation of a critical ground state is hampered by the closing of its energy gap as the system size increases. However, this gap is directly relevant only for a unifor…
Bang-bang preparation of quantum many-body ground states in two dimensions: optimization of the algorithm with a two-dimensional tensor network
Yintai Zhang, Jacek Dziarmaga
A bang-bang (BB) algorithm prepares the ground state of a two-dimensional (2D) quantum many-body Hamiltonian by evolving an initial product state alternating between $H…
Efficient Representation of Minimally Entangled Typical Thermal States in two dimensions via Projected Entangled Pair States
Aritra Sinha, Marek M. Rams, Jacek Dziarmaga
The Minimally Entangled Typical Thermal States (METTS) are an ensemble of pure states, equivalent to the Gibbs thermal state, that can be efficiently represented by tensor networks…
Biased dynamics of the miscible-immiscible quantum phase transition in a binary Bose-Einstein condensate
Francis A. Bayocboc, Jacek Dziarmaga, Wojciech H. Zurek
A quantum phase transition from the miscible to the immiscible phase of a quasi-one-dimensional binary Bose-Einstein condensate is driven by ramping down the coupling amplitude of…
Tensor network simulation of the quantum Kibble-Zurek quench from the Mott to superfluid phase in the two-dimensional Bose-Hubbard model
Jacek Dziarmaga, Jakub M. Mazur
Quantum simulations of the Bose-Hubbard model (BHM) at commensurate filling can follow spreading of correlations after a sudden quench for times long enough to estimate their propa…
