Uhlmann Fidelity and Fidelity Susceptibility for Integrable Spin Chains at Finite Temperature: Exact Results
Michał Białończyk, Fernando Javier Gómez-Ruiz, Adolfo del Campo
We derive the exact expression for the Uhlmann fidelity between arbitrary thermal Gibbs states of the quantum XY model in a transverse field with finite system size. Using it, we c…
Exact Delta Kick Cooling, Time-Optimal Control of Scale-Invariant Dynamics, and Shortcuts to Adiabaticity Assisted by Kicks
Léonce Dupays, David C. Spierings, Aephraim M. Steinberg +1
Delta kick cooling (DKC) is used to compress the momentum distribution of ultracold quantum matter. It combines expansion dynamics with the use of kick pulses, designed via classic…
Universal Statistics of Vortices in a Newborn Holographic Superconductor: Beyond the Kibble-Zurek Mechanism
Adolfo del Campo, Fernando Javier Gómez-Ruiz, Zhi-Hong Li +3
Traversing a continuous phase transition at a finite rate leads to the breakdown of adiabatic dynamics and the formation of topological defects, as predicted by the celebrated Kibb…
Thermofield dynamics: Quantum Chaos versus Decoherence
Zhenyu Xu, Aurelia Chenu, Tomaž Prosen +1
Quantum chaos imposes universal spectral signatures that govern the thermofield dynamics of a many-body system in isolation. The fidelity between the initial and time-evolving ther…
Exact ground states of quantum many-body systems under confinement
Adolfo del Campo
Knowledge of the ground state of a homogeneous quantum many-body system can be used to find the exact ground state of a dual inhomogeneous system with a confining potential. For th…
Universal finite-time thermodynamics of many-body quantum machines from Kibble-Zurek scaling
Revathy B. S., Victor Mukherjee, Uma Divakaran +1
We demonstrate the existence of universal features in the finite-time thermodynamics of quantum machines by considering a many-body quantum Otto cycle in which the working medium i…
Time-information uncertainty relations in thermodynamics
Schuyler B. Nicholson, Luis Pedro Garcia-Pintos, Adolfo del Campo +1
Physical systems that power motion and create structure in a fixed amount of time dissipate energy and produce entropy. Whether living or synthetic, systems performing these dynami…
Probing the Universality of Topological Defect Formation in a Quantum Annealer: Kibble-Zurek Mechanism and Beyond
Yuki Bando, Yuki Susa, Hiroki Oshiyama +7
The number of topological defects created in a system driven through a quantum phase transition exhibits a power-law scaling with the driving time. This universal scaling law is th…
Quantum Statistical Enhancement of the Collective Performance of Multiple Bosonic Engines
Gentaro Watanabe, B. Prasanna Venkatesh, Peter Talkner +2
We consider an ensemble of indistinguishable quantum machines and show that quantum statistical effects can give rise to a genuine quantum enhancement of the collective thermodynam…
Experimentally testing quantum critical dynamics beyond the Kibble-Zurek mechanism
Jin-Ming Cui, Fernando Javier Gómez-Ruiz, Yun-Feng Huang +3
We experimentally probe the distribution of kink pairs resulting from driving a one-dimensional quantum Ising chain through the paramagnet-ferromagnet quantum phase transition, usi…
Focus on Shortcuts to Adiabaticity
Adolfo del Campo, Kihwan Kim
Shortcuts to Adiabaticity (STA) constitute driving schemes that provide an alternative to adiabatic protocols to control and guide the dynamics of classical and quantum systems wit…
Spontaneous symmetry breaking induced by quantum monitoring
Luis Pedro García-Pintos, Diego Tielas, Adolfo del Campo
Spontaneous symmetry breaking (SSB) is responsible for structure formation in scenarios ranging from condensed matter to cosmology. SSB is broadly understood in terms of perturbati…
Shortcuts to adiabaticity in Fermi gases
Pengpeng Diao, Shujin Deng, Fang Li +4
Shortcuts to adiabaticity (STA) provide an alternative to adiabatic protocols to guide the dynamics of the system of interest without the requirement of slow driving. We report the…
