Time-resolved observation of thermalization in an isolated quantum system
Govinda Clos, Diego Porras, Ulrich Warring +1
We use trapped atomic ions forming a hybrid Coulomb crystal, and exploit its phonons to study an isolated quantum system composed of a single spin coupled to an engineered bosonic…
Topological phases of shaken quantum Ising lattices
Samuel Fernandez-Lorenzo, Juan Jose Garcia-Ripoll, Diego Porras
The quantum compass model consists of a two-dimensional square spin lattice where the orientation of the spin-spin interactions depends on the spatial direction of the bonds. It ha…
Spontaneous-symmetry-breaking assisted quantum sensors
Peter A. Ivanov, Kilian Singer, Nikolay V. Vitanov +1
We propose a quantum sensing scheme for measuring weak forces based on a symmetry-breaking adiabatic transition in the quantum Rabi model. We show that the system described by the…
Interaction-Dependent Photon-Assisted Tunneling in Optical Lattices: A Quantum Simulator of Strongly-Correlated Electrons and Dynamical Gauge Fields
A. Bermudez, D. Porras
We introduce a scheme that combines photon-assisted tunneling by a moving optical lattice with strong Hubbard interactions, and allows for the quantum simulation of paradigmatic qu…
Rabi Lattice models with discrete gauge symmetry: phase diagram and implementation in trapped ion quantum simulators
Pedro Nevado, Diego Porras
We study a spin-boson chain that exhibits a local Z2 symmetry. We investigate the quantum phase diagram of the model by means of perturbation theory, mean field theory and the Dens…
Photon-mediated qubit interactions in 1D discrete and continous models
Guillermo Diaz-Camacho, Diego Porras, Juan Jose Garcia-Ripoll
In this work we study numerically and analytically the interaction of two qubits in a one-dimensional waveguide, as mediated by the photons that propagate through the guide. We dev…
