Diffusion and transport in locally disordered driven lattices
Thomas Wulf, Alexander Okupnik, Peter Schmelcher
We study the effect of disorder on the particle density evolution in a classical Hamiltonian driven lattice setup. If the disorder is localized within a finite sub-domain of the la…
Chaotic and ballistic dynamics in time-driven quasiperiodic lattices
Thomas Wulf, Peter Schmelcher
We investigate the nonequilibrium dynamics of classical particles in a driven quasiperiodic lattice based on the Fibonacci sequence. An intricate transient dynamics of extraordinar…
Freezing, accelerating and slowing directed currents in real time with superimposed driven lattices
Aritra K. Mukhopadhyay, Benno Liebchen, Thomas Wulf +1
We provide a generic scheme offering real time control of directed particle transport in superimposed driven lattices. This scheme allows to accelerate, slow and freeze the transpo…
Exposing local symmetries in distorted driven lattices via time-averaged invariants
Thomas Wulf, Christian V. Morfonios, Fotis K. Diakonos +1
Time-averaged two-point currents are derived and shown to be spatially invariant within domains of local translation or inversion symmetry for arbitrary time-periodic quantum syste…
Resonant quantum dynamics of few ultracold bosons in periodically driven finite lattices
S. I. Mistakidis, T. Wulf, A. Negretti +1
The out-of-equilibrium dynamics of finite ultracold bosonic ensembles in periodically driven one-dimensional optical lattices is investigated. Our study reveals that the driving en…
Site-selective particle deposition in periodically driven quantum lattices
Thomas Wulf, Benno Liebchen, Peter Schmelcher
We demonstrate that a site-dependent driving of a periodic potential allows for the controlled manipulation of a quantum particle on length scales of the lattice spacing. Specifica…
Symmetries and transport in site-dependently driven quantum lattices
Thomas Wulf, Christoph Petri, Benno Liebchen +1
We explore the quantum dynamics of particles in a spatiotemporally driven lattice. A powerful numerical scheme is developed, which provides us with the Floquet modes and thus enabl…
Disorder-induced regular dynamics in oscillating lattices
Thomas Wulf, Benno Liebchen, Peter Schmelcher
We explore the impact of weak disorder on the dynamics of classical particles in a periodically oscillating lattice. It is demonstrated that the disorder induces a hopping process…
Analysis of interface conversion processes of ballistic and diffusive motion in driven superlattices
Thomas Wulf, Christoph Petri, Benno Liebchen +1
We explore the non-equilibrium dynamics of non-interacting classical particles in a one-dimensional driven superlattice which is composed of domains exposed to different time-depen…
Dynamics of a thin liquid film with surface rigidity and spontaneous curvature
Michael H. Köpf, Svetlana V. Gurevich, Thomas Wulf +1
The effect of rigid surfaces on the dynamics of thin liquid films which are amenable to the lubrication approximation is considered. It is shown that the Helfrich energy of the lay…
