Dynamics and energy spectra of aperiodic discrete-time quantum walks
C. V. Ambarish, N. Lo Gullo, Th. Busch +2
Deterministically aperiodic sequences are an intermediary between periodic sequences and completely random sequences. Materials which are translationally periodic have Bloch-like e…
Spatial non-adiabatic passage using geometric phases
Albert Benseny, Anthony Kiely, Yongping Zhang +2
Quantum technologies based on adiabatic techniques can be highly effective, but often at the cost of being very slow. Here we introduce a set of experimentally realistic, non-adiab…
Proposal for detection of a single electron spin in a microwave resonator
P. Haikka, Y. Kubo, A. Bienfait +2
We propose a method for detecting the presence of a single spin in a crystal by coupling it to a high-quality factor superconducting planar resonator. By confining the microwave fi…
Probing the out-of-equilibrium dynamics of two interacting atoms
Tim Keller, Thomás Fogarty
We study the out-of-equilibrium dynamics of two interacting atoms in a one-dimensional harmonic trap after a quench by a tightly pinned impurity atom. We make use of an approximate…
On the classical Schrödinger equation
Albert Benseny, David Tena, Xavier Oriols
In this paper, the classical Schrödinger equation, which allows the study of classical dynamics in terms of wave functions, is analyzed theoretically and numerically. First, depart…
Localization transition in presence of cavity backaction
Katharina Rojan, Rebecca Kraus, Thomás Fogarty +3
We study the localization transition of an atom confined by an external optical lattice in a high-finesse cavity. The atom-cavity coupling yields an effective secondary lattice pot…
Optomechanical many-body cooling using frustration
Thomás Fogarty, Haggai Landa, Cecilia Cormick +1
We show that the vibrations of an ion Coulomb crystal can be cooled to the zero-point motion through the optomechanical coupling with a high-finesse cavity. Cooling results from th…
Non-Equilibrium Thermodynamics of Harmonically Trapped Bosons
Miguel Ángel García-March, Thomás Fogarty, Steve Campbell +2
We apply the framework of non-equilibrium quantum thermodynamics to the physics of quenched small-sized bosonic quantum gases in a one-dimensional harmonic trap. We show that dynam…
Shaken not stirred: Creating exotic angular momentum states by shaking an optical lattice
Anthony Kiely, Albert Benseny, Thomas Busch +1
We propose a method to create higher orbital states of ultracold atoms in the Mott regime of an optical lattice. This is done by periodically modulating the position of the trap mi…
Spatial adiabatic passage: a review of recent progress
Ricard Menchon-Enrich, Albert Benseny, Verònica Ahufinger +3
Adiabatic techniques are known to allow for engineering quantum states with high fidelity. This requirement is currently of large interest, as applications in quantum information r…
Natural classical limit for the center of mass of many-particle quantum systems
Xavier Oriols, Albert Benseny
We discuss the conditions for the classicality of quantum states with a very large number of identical particles. By treating the center of mass as a Bohmian particle, we show that…
Non-adiabatic generation of NOON states in a Tonks--Girardeau gas
J. Schloss, A. Benseny, J. Gillet +2
With adiabatic techniques, it is possible to create quantum superposition states with high fidelity while exercising limited control over the parameters of a system. However, becau…
