TY - JOUR A1 - Nalbach, Peter A1 - Klinkenberg, Nico A1 - Palm, Timo A1 - Müller, Niklas T1 - Environmental rocking ratchet: Environmental rectification by a harmonically driven avoided crossing T2 - Physical Review E N2 - We propose a rocking ratchet designed as a symmetric quantum two-state system driven by a single periodic harmonic force and influenced symmetrically by thermal fluctuations. We show that the necessary broken symmetry can dynamically be achieved by a thermal environment that couples to the energy difference between the two states and the tunnel coupling between them. The quantum two-state system is driven by the harmonic periodic drive through its avoided crossing. The correspondingly driven dissipative quantum dynamics results on average in a finite population difference between both states. This then causes directed particle transport.
