Measuring nonequilibrium retarded spin-spin Green's functions in an ion-trap based quantum simulator
Bryce T. Yoshimura, J. K. Freericks
Recent work proposed a variant on Ramsey interferometry for coupled spin- systems that directly measures the retarded spin-spin Green's function. We expand on that work by inv…
Bang-bang shortcut to adiabaticity in trapped ion quantum simulators
Shankar Balasubramanian, Shuyang Han, Bryce T. Yoshimura +1
We model the bang-bang optimization protocol as a shortcut to adiabaticity in the ground-state preparation of an ion-trap-based quantum simulator. Compared to a locally adiabatic e…
Nonequilibrium response of an electron mediated charge-density-wave-ordered material to a large dc electric field
O. P. Matveev, A. M. Shvaika, T. P. Devereaux +1
Using the Kadanoff-Baym-Keldysh formalism, we employ nonequilibrium dynamical mean-field theory to exactly solve for the nonlinear response of an electron-mediated charge-density-w…
Creating thermal distributions from diabatic excitations in ion-trap-based quantum simulation
M. H. Lim, B. T. Yoshimura, J. K. Freericks
The goal of adiabatic ground-state preparation is to start a simple quantum system in its ground state and adiabatically evolve the Hamiltonian to a complex one, maintaining the gr…
Zone-center phonons of bulk, few-layer, and monolayer 1T-TaS: Detection of the commensurate charge density wave phase through Raman scattering
Oliver R. Albertini, Rui Zhao, Rebecca L. McCann +5
We present first-principles calculations of the vibrational properties of the transition metal dichalcogenide 1T-TaS for various thicknesses in the high-temperature (undistorte…
Exact calculation of phonon effects on spin squeezing
D. Dylewsky, J. K. Freericks, M. L. Wall +2
Theoretical models of spins coupled to bosons provide a simple setting for studying a broad range of important phenomena in many-body physics, from virtually mediated interactions…
