Structural phase transitions and topological defects in ion Coulomb crystals
Heather L. Partner, Ramil Nigmatullin, Tobias Burgermeister +7
We use laser-cooled ion Coulomb crystals in the well-controlled environment of a harmonic radiofrequency ion trap to investigate phase transitions and defect formation. Topological…
Controlling quantum critical dynamics of isolated systems
A. del Campo, K. Sengupta
Controlling the non adiabatic dynamics of isolated quantum systems driven through a critical point is of interest in a variety of fields ranging from quantum simulation to finite-t…
High-fidelity rapid ground-state loading of an ultracold gas into an optical lattice
Shumpei Masuda, Katsuhiro Nakamura, Adolfo del Campo
A protocol is proposed for the rapid coherent loading of a Bose-Einstein condensate into the ground state of an optical lattice, without residual excitation associated with the bre…
Adiabatic tracking of quantum many-body dynamics
Hamed Saberi, Tomáš Opatrný, Klaus Mølmer +1
The nonadiabatic dynamics of a many-body system driven through a quantum critical point can be controlled using counterdiabatic driving, where the formation of excitations is suppr…
Quantum Simulation of Dissipative Processes without Reservoir Engineering
R. Di Candia, J. S. Pedernales, A. del Campo +2
We present a quantum algorithm to simulate general finite dimensional Lindblad master equations without the requirement of engineering the system-environment interactions. The prop…
Universal far-from-equilibrium Dynamics of a Holographic Superconductor
Julian Sonner, Adolfo del Campo, Wojciech H. Zurek
Symmetry breaking phase transitions are an example of non-equilibrium processes that require real time treatment, a major challenge in strongly coupled systems without long-lived q…
Tuning heat transport in trapped-ion chains across a structural phase transition
Antonia Ruiz, Daniel Alonso, Martin B. Plenio +1
We explore heat transport across an ion Coulomb crystal beyond the harmonic regime by tuning it across the structural phase transition between the linear and zigzag configurations.…
