Equilibrium and Non-equilibrium Gross-Pitaevskii Lattice Dynamics: Interactions, Disorder, and Thermalization
Yagmur Kati
The interplay of fluctuations, ergodicity, and disorder in many-body interacting systems has been striking attention for half a century, pivoted on two celebrated phenomena: Anders…
Density Resolved Wave Packet Spreading in Disordered Gross-Pitaevskii Lattices
Yagmur Kati, Xiaoquan Yu, Sergej Flach
We perform novel energy and norm density resolved wave packet spreading studies in the disordered Gross-Pitaevskii (GP) lattice to confine energy density fluctuations. We map the l…
Dynamical glass in weakly non-integrable Klein-Gordon chains
Carlo Danieli, Thudiyangal Mithun, Yagmur Kati +2
Integrable many-body systems are characterized by a complete set of preserved actions. Close to an integrable limit, a {\it nonintegrable} perturbation creates a coupling network i…
Dynamical Glass and Ergodization Times in Classical Josephson Junction Chains
Mithun Thudiyangal, Carlo Danieli, Yagmur Kati +1
Models of classical Josephson junction chains turn integrable in the limit of large energy densities or small Josephson energies. Close to these limits the Josephson coupling betwe…
