Invariant currents and scattering off locally symmetric potential landscapes
P. A. Kalozoumis, C. Morfonios, F. K. Diakonos +1
We study the effect of discrete symmetry breaking in inhomogeneous scattering media within the framework of generic wave propagation. Our focus is on one-dimensional scattering pot…
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…
Invariants of broken discrete symmetries
P. Kalozoumis, C. Morfonios, F. K. Diakonos +1
The parity and Bloch theorems are generalized to the case of broken global symmetry. Local inversion or translation symmetries are shown to yield invariant currents that characteri…
