Achieving fast high-fidelity optimal control of many-body quantum dynamics
Jesper Hasseriis Mohr Jensen, Frederik Skovbo Møller, Jens Jakob Sørensen +1
We demonstrate the efficiency of a recent exact-gradient optimal control methodology by applying it to a challenging many-body problem, crossing the superfluid to Mott-insulator ph…
Euler-scale dynamical correlations in integrable systems with fluid motion
Frederik S. Møller, Gabriele Perfetto, Benjamin Doyon +1
We devise an iterative scheme for numerically calculating dynamical two-point correlation functions in integrable many-body systems, in the Eulerian scaling limit. Expressions for…
Extension of the Generalized Hydrodynamics to the Dimensional Crossover Regime
Frederik Møller, Chen Li, Igor Mazets +5
In an effort to address integrability breaking in cold gas experiments, we extend the integrable hydrodynamics of the 1d Lieb-Liniger model with two additional components represent…
Approximate Dynamics Lead to More Optimal Control: Efficient Exact Derivatives
Jesper Hasseriis Mohr Jensen, Frederik Skovbo Møller, Jens Jakob Sørensen +1
Accurate derivatives are important for efficiently locally traversing and converging in quantum optimization landscapes. By deriving analytically exact control derivatives (gradien…
Decay and recurrence of non-Gaussian correlations in a quantum many-body system
Thomas Schweigler, Marek Gluza, Mohammadamin Tajik +8
Gaussian models provide an excellent effective description of many quantum many-body systems ranging from condensed matter systems all the way to neutron stars. Gaussian states are…
Introducing iFluid: a numerical framework for solving hydrodynamical equations in integrable models
Frederik S. Møller, Jörg Schmiedmayer
We present an open-source Matlab framework, titled iFluid, for simulating the dynamics of integrable models using the theory of generalized hydrodynamics (GHD). The framework provi…
