A graphene edge-mediated quantum gate
Phillip Weinberg, Adrian E. Feiguin
We propose a quantum gate architecture that allows for the systematic control of the effective exchange interactions between magnetic impurities embedded in nano-scale graphene fla…
Enhanced Convergence of Quantum Typicality using a Randomized Low-Rank Approximation
Phillip Weinberg
We present a method to reduce the variance of stochastic trace estimators used in quantum typicality (QT) methods via a randomized low-rank approximation of the finite-temperature…
Scaling and diabatic effects in quantum annealing with a D-Wave device
Phillip Weinberg, Marek Tylutki, Jami M. Rönkkö +5
We discuss quantum annealing of the two-dimensional transverse-field Ising model on a D-Wave device, encoded on lattices with . Analyzing the residual energy…
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…
