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…
Quantification and Control of non-Markovian Evolution in Finite Quantum Systems via Feedback
Nicholas Chancellor, Christoph Petri, Lorenzo Campos Venuti +2
We consider the unitary time evolution of continuous quantum mechanical systems confined to a cavity in contact with a finite bath of variable size. Measures for Markovianity for s…
Non-Markovian Equilibration Controlled by Symmetry Breaking
Nicholas Chancellor, Christoph Petri, Stephan Haas
We study the effects of symmetry breaking on non-Markovian dynamics in various system-bath arrangements. It is shown that by breaking certain symmetries features signaling non-Mark…
Neutral particle focusing in composite driven dissipative billiards
Benno Liebchen, Christoph Petri, Mario Krizanac +1
Dynamical focusing of ensembles of neutral particles in energy and configuration space has been demonstrated recently [C. Petri et al. 2010, Phys. Rev. E (R) {\bf 82}, 035204] usin…
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…
Critical non-equilibrium steady states of the Lorentz channel
Alexandros K. Karlis, Fotios K. Diakonos, Christoph Petri +1
We investigate the transport properties of non-interacting particles propagating in a finite Lorentz channel (LC). We show that interparticle power-law correlations emerge, when th…
Phase Space Interpretation of Exponential Fermi Acceleration
Benno Liebchen, Robert Büchner, Christoph Petri +3
Recently, the occurrence of exponential Fermi acceleration has been reported in a rectangular billiard with an oscillating bar inside [K. Shah, D. Turaev, and V. Rom-Kedar, Phys. R…
Formation of density waves via interface conversion of ballistic and diffusive motion
Christoph Petri, Florian Lenz, Benno Liebchen +2
We develop a mechanism for the controlled conversion of ballistic to diffusive motion and vice versa. This process takes place at the interfaces of domains with different time-depe…
Patterned Deposition of Particles in Spatio-temporally Driven Lattices
Benno Liebchen, Christoph Petri, Florian Lenz +1
We present and analyze mechanisms for the patterned deposition of particles in a spatio-temporally driven lattice. The working principle is based on the breaking of the spatio-temp…
Correlations and pair emission in the escape dynamics of ions from one-dimensional traps
Christoph Petri, Stefan Meyer, Florian Lenz +1
We explore the non-equilibrium escape dynamics of long-range interacting ions in one-dimensional traps. The phase space of the few ion setup and its impact on the escape properties…
Phase space focusing in dissipative driven elliptical billiards
Christoph Petri, Florian Lenz, Fotis Diakonos +1
We study the interplay of dissipation and harmonic driving in the elliptical billiard. These two competing processes balance each other, which leads to a destruction of Fermi accel…
Directed transport and localization in phase-modulated driven lattices
Christoph Petri, Florian Lenz, Fotis K. Diakonos +1
We explore the dynamics of non-interacting particles loaded into a phase-modulated one-dimensional lattice formed by laterally oscillating square barriers. Tuning the parameters of…
Evolutionary phase space in driven elliptical billiards
F. Lenz, C. Petri, F. N. R. Koch +2
We perform the first long-time exploration of the classical dynamics of a driven billiard with a four dimensional phase space. With increasing velocity of the ensemble we observe a…
Dynamical trapping and chaotic scattering of the harmonically driven barrier
Florian R. N. Koch, Florian Lenz, Christoph Petri +2
A detailed analysis of the classical nonlinear dynamics of a single driven square potential barrier with harmonically oscillating position is performed. The system exhibits dynamic…
