Programmable quantum simulation of anharmonic dynamics
Cameron McGarry, Teerawat Chalermpusitarak, Kai Schwennicke +9
Continuous-variable-discrete-variable (CV-DV) quantum simulators offer a natural route to simulating bosonic dynamics relevant to many branches of physics and chemistry. However, p…
Accelerating dynamical mean-field theory convergence by preconditioning with computationally cheaper quantum embedding methods
E. M. Makaresz, O. Gingras, Tsung-Han Lee +3
Dynamical mean-field theory (DMFT) is a cornerstone technique for studying strongly correlated electronic systems. However, each DMFT step is computationally demanding, and many it…
Using bosons to improve resource efficiency of quantum simulation of vibronic molecular dynamics
Henry L. Nourse, Vanessa C. Olaya-Agudelo, Ivan Kassal
Simulating chemical dynamics is computationally challenging, especially for nonadiabatic dynamics, where numerically exact classical simulations scale exponentially with system siz…
Fingerprints of collective magnetic excitations in inelastic electron tunneling spectroscopy
Finnian Rist, Henry L. Nourse, Ben J. Powell
Spin-flip inelastic electron tunneling spectroscopy allows magnetic materials to be probed at the single-atom level via scanning tunneling microscopy. Previously, the local spectra…
Equilibration of Non-interacting Photons and Quantum Signatures of Chaos
V. M. Bastidas, H. L. Nourse, A. Sakurai +4
Equilibration plays a fundamental role in our understanding of statistical mechanics and the long-time dynamics of many-body systems. In quantum systems, the route to equilibration…
Quantum simulation of thermodynamics: Maxwell relations for pair correlations
F. Rist, R. S. Watson, H. L. Nourse +2
Quantum simulators hold enormous promise for advancing the modelling of materials and understanding emergent physics, such as high temperature superconductivity and topological ord…
