Shortcuts to adiabaticity with a quantum control field
Emma C. King, Giovanna Morigi, Raphaël Menu
Quantum adiabatic dynamics is the crucial element of adiabatic quantum computing and quantum annealing. Shortcuts to adiabaticity enable acceleration of the computational time by s…
Universal cooling of quantum systems via randomized measurements
Josias Langbehn, George Mouloudakis, Emma King +5
Designing cooling protocols is believed to require knowledge of the system spectrum. In contrast, cooling in nature occurs whenever the system is coupled to a cold bath. How does n…
Speeding up Quantum Annealing with Engineered Dephasing
Mykolas Sveistrys, Josias Langbehn, Raphaël Menu +3
Building on the insight that engineered noise, specifically, engineered dephasing can enhance the adiabaticity of controlled quantum dynamics, we investigate how a dephasing-genera…
Dynamical phases of a BEC in a bad optical cavity at optomechanical resonance
Gage W. Harmon, Giovanna Morigi, Simon B. Jäger
We study the emergence of dynamical phases of a Bose-Einstein condensate that is optomechanically coupled to a dissipative cavity mode and transversally driven by a laser. We focus…
Spin self-organization in an optical cavity facilitated by inhomogeneous broadening
Marc Nairn, Luigi Giannelli, Giovanna Morigi +3
We study the onset of collective spin-self-organization in a thermal ensemble of driven two-level atoms confined in an optical cavity. The atoms spontaneously form a spin-pattern a…
Self-organized transport in noisy dynamic networks
Frederic Folz, Kurt Mehlhorn, Giovanna Morigi
We present a numerical study of multi-commodity transport in a noisy, nonlinear network. The nonlinearity determines the dynamics of the edge capacities, which can be amplified or…
Fractal ground state of ion chains in periodic potentials
Raphaël Menu, Jorge Yago Malo, Vladan Vuletić +2
Trapped ions in a periodic potential are a paradigm of a frustrated Wigner crystal. The dynamics is captured by a long-range Frenkel-Kontorova model. The classical ground state can…
Fast storage of photons in cavity-assisted quantum memories
Johann S. Kollath-Bönig, Luca Dellantonio, Luigi Giannelli +3
Ideal photonic quantum memories can store arbitrary pulses of light with unit efficiency. This requires operating in the adiabatic regime, where pulses have a duration much longer…
Quantum frustrated Wigner chains
Raphaël Menu, Jorge Yago Malo, Vladan Vuletić +2
A Wigner chain in a periodic potential is a paradigmatic example of geometric frustration with long-range interactions. The dynamics emulates the Frenkel-Kontorova model with Coulo…
Adiabatic quantum trajectories in engineered reservoirs
Emma C. King, Luigi Giannelli, Raphaël Menu +2
We analyze the efficiency of protocols for adiabatic quantum state transfer assisted by an engineered reservoir. The target dynamics is a quantum trajectory in the Hilbert space an…
Quantum phases of hardcore bosons with repulsive dipolar density-density interactions on two-dimensional lattices
J. A. Koziol, G. Morigi, K. P. Schmidt
We analyse the ground-state quantum phase diagram of hardcore Bosons interacting with repulsive dipolar potentials. The bosons dynamics is described by the extended-Bose-Hubbard Ha…
Systematic Analysis of Crystalline Phases in Bosonic Lattice Models with Algebraically Decaying Density-Density Interactions
J. A. Koziol, A. Duft, G. Morigi +1
We propose a general approach to analyse diagonal ordering patterns in bosonic lattice models with algebraically decaying density-density interactions on arbitrary lattices. The ke…
