Convection Patterns in Nonequilibrium Kawasaki Dynamics at Low Temperature
Meander Van den Brande, Kyosuke Adachi, Francois Huveneers
We study a conservative stochastic lattice gas (Kawasaki dynamics) coupled in the bulk to a heat bath, which leads to standard phase separation at low uniform temperatures. Instead…
Absence of Normal Heat Conduction in Strongly Disordered Interacting Quantum Chains
Wojciech De Roeck, Lydia Giacomin, Francois Huveneers +1
We prove that in strongly disordered, interacting, quantum chains, the conductance of a chain of length vanishes faster than . This means that transport is anomalous in su…
Sub-Power Law Decay of the Wave Packet Maximum in Disordered Anharmonic Chains
Wojciech De Roeck, Lydia Giacomin, Amirali Hannani +1
We show that the peak of an initially localized wave packet in one-dimensional nonlinear disordered chains decays more slowly than any power law of time. The systems under investig…
Long persistence of localization in a disordered anharmonic chain beyond the atomic limit
Wojciech De Roeck, François Huveneers, Oskar A. ProÅniak
We establish rigorous bounds on the decorrelation time and thermal transport in the disordered Klein-Gordon chain with a quartic on-site potential, governed by a parameter . At…
Slow dissipation and spreading in disordered classical systems: A direct comparison between numerics and mathematical bounds
Wojciech De Roeck, François Huveneers, Oskar A. ProÅniak
We study the breakdown of Anderson localization in the one-dimensional nonlinear Klein-Gordon chain, a prototypical example of a disordered classical many-body system. A series of…
