Symmetry enhanced first-order phase transition in a two-dimensional quantum magnet
Bowen Zhao, Phillip Weinberg, Anders W. Sandvik
Theoretical studies of quantum phase transitions have suggested critical points with higher symmetries than those of the underlying Hamiltonian. Here we demonstrate a surprising em…
QuSpin: a Python Package for Dynamics and Exact Diagonalisation of Quantum Many Body Systems. Part II: bosons, fermions and higher spins
Phillip Weinberg, Marin Bukov
We present a major update to QuSpin, SciPostPhys.2.1.003 -- an open-source Python package for exact diagonalization and quantum dynamics of arbitrary boson, fermion and spin many-b…
Anomalous quantum-critical scaling corrections in two-dimensional antiferromagnets
Nvsen Ma, Phillip Weinberg, Hui Shao +3
We study the Néel-paramagnetic quantum phase transition in two-dimensional dimerized Heisenberg antiferromagnets using finite-size scaling of quantum Monte Carlo data. We r…
Glassy Phase of Optimal Quantum Control
Alexandre G. R. Day, Marin Bukov, Phillip Weinberg +2
We study the problem of preparing a quantum many-body system from an initial to a target state by optimizing the fidelity over the family of bang-bang protocols. We present compell…
Asymptotic Prethermalization in Periodically Driven Classical Spin Chains
Owen Howell, Phillip Weinberg, Dries Sels +2
We reveal a continuous dynamical heating transition between a prethermal and an infinite-temperature stage in a clean, chaotic periodically driven classical spin chain. The transit…
