Langevin dynamics of generalized spins as SU() coherent states
David Dahlbom, Cole Miles, Hao Zhang +2
Classical models of spin systems traditionally retain only the dipole moments, but a quantum spin state will frequently have additional structure. Spins of magnitude have $N=2S…
Geometric integration of classical spin dynamics via a mean-field Schrödinger equation
David Dahlbom, Hao Zhang, Cole Miles +3
The Landau-Lifshitz equation describes the time-evolution of magnetic dipoles, and can be derived by taking the classical limit of a quantum mechanical spin Hamiltonian. To take th…
Fast and scalable quantum Monte Carlo simulations of electron-phonon models
Benjamin Cohen-Stead, Owen Bradley, Cole Miles +3
We introduce methodologies for highly scalable quantum Monte Carlo simulations of electron-phonon models, and report benchmark results for the Holstein model on the square lattice.…
Dynamical tuning of the chemical potential to achieve a target particle number in grand canonical Monte Carlo simulations
Cole Miles, Benjamin Cohen-Stead, Owen Bradley +3
We present a method to facilitate Monte Carlo simulations in the grand canonical ensemble given a target mean particle number. The method imposes a fictitious dynamics on the chemi…
