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…

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…
