Decoherence-protected quantum register of nuclear spins in diamond

FJ González, R Coto - Quantum Science and Technology, 2022 - iopscience.iop.org
Solid-state quantum registers are exceptional for storing quantum information at room
temperature with long coherence time. Nevertheless, practical applications toward quantum …

Generation and protection of a maximally entangled state between many modes in an optical network with dissipation

R Coto, M Orszag, V Eremeev - Physical Review A, 2016 - APS
We present a three-cavity network model with two modes in each cavity and a nonlinear
medium that generates a Kerr-type interaction via both self-phase and cross-phase …

One-BEC-species coherent oscillations with frequency controlled by a second species atom number

L Morales-Molina, E Arévalo - New Journal of Physics, 2022 - iopscience.iop.org
Controlling the tunneling of atoms of one species using a different atom species is a
fundamental step in the development of a new class of atom quantum devices, where …

Quasianalytical treatment of the spin Seebeck effect on the molecule

G Lefkidis, SA Reyes - Physical Review B, 2016 - APS
We present a method to calculate from first principles the spin Seebeck effect on finite
systems. Our method, which is suited for all ab initio, quantum-chemistry-based results, is …

Harnessing currents of particles for spectroscopy in small-ring lattices with binary mixtures

L Morales-Molina, SA Reyes, E Arévalo - Europhysics Letters, 2020 - iopscience.iop.org
We propose a method to probe ground states with distinct properties in binary mixtures
trapped in small-ring lattices. The technique exploits the nonequilibrium particle current …

Hysteresis of noninteracting and spin-orbit-coupled atomic Fermi gases with relaxation

M Metcalf, CY Lai, CC Chien - Physical Review A, 2016 - APS
Hysteresis can be found in driven many-body systems such as magnets and superfluids.
Rate-dependent hysteresis arises when a system is driven periodically while relaxing …

Pair correlations as a signature of entanglement: A bosonic mixture in gauge field ring lattices

L Morales-Molina, SA Reyes, E Arévalo - Europhysics Letters, 2016 - iopscience.iop.org
We study the pair-superfluid phase and entanglement of a Bose-Bose mixture of ultracold
atoms in a ring lattice in the presence of a synthetic gauge field. Special attention is given to …

Reversing the persistent current of particles in a driven optical ring lattice

L Morales-Molina, E Arévalo - Physical Review A, 2015 - APS
We study the dynamics of persistent bosonic currents in closed-loop atom circuits in the form
of ring lattices and under the action of time periodic driving. The closed-loop atom circuits …
