Ab initio molecular dynamics on the electronic Boltzmann equilibrium distribution
(IOP Publishing, 2010-08-31)We prove that for a combined system of classical and quantum particles, it is possible to describe a dynamics for the classical particles that incorporates in a natural way the Boltzmann equilibrium population for the ... -
Digital Quantum Simulation of Spin Models with Circuit Quantum Electrodynamics
Salathé, Y.; Mondal, M.; Oppliger, M.; Heinsoo, J.; Kurpiers, P.; Potočnik, A.; Mezzacapo, Antonio; Las Heras García, Urtzi; Lamata Manuel, Lucas
; Solano Villanueva, Enrique Leónidas ; Filipp, S.; Wallraff, A. (American Physical Society, 2015-06-17)
Systems of interacting quantum spins show a rich spectrum of quantum phases and display interesting many-body dynamics. Computing characteristics of even small systems on conventional computers poses significant challenges. ... -
Energy and momentum transfer in one-dimensional trapped gases by stimulated light scattering
(IOP Publishing, 2015-06-10)In ultracold atoms settings, inelastic light scattering is a preeminent technique to reveal static and dynamic properties at nonzero momentum. In this work, we investigate an array of one-dimensional trapped Bose gases, ... -
Entanglement negativity in the harmonic chain out of equilibrium
(IOP Publishing, 2014-12-08)We study the entanglement in a chain of harmonic oscillators driven out of equilibrium by preparing the two sides of the system at different temperatures, and subsequently joining them together. The steady state is constructed ... -
Long-lived oscillatory incoherent electron dynamics in molecules: trans-polyacetylene oligomers
(IOP Publishing, 2013-04)We identify an intriguing feature of the electron-vibrational dynamics of molecular systems via a computational examination of trans-polyacetylene oligomers. Here, via the vibronic interactions, the decay of an electron ... -
Permutationally invariant state reconstruction
(IOP Publishing, 2012-10)Feasible tomography schemes for large particle numbers must possess, besides an appropriate data acquisition protocol, an efficient way to reconstruct the density operator from the observed finite data set. Since state ... -
Real-Time Dynamics in U(1) Lattice Gauge Theories with Tensor Networks
Pichler, T.; Dalmonte, M.; Rico Ortega, Enrique; Zoller, P.; Montangero, S. (American Physical Society, 2016-03-03)
Tensor network algorithms provide a suitable route for tackling real-time-dependent problems in lattice gauge theories, enabling the investigation of out-of-equilibrium dynamics. We analyze a U(1) lattice gauge theory in ...
