Noise-assisted classical adiabatic pumping in a symmetric periodic potential.
We consider a classical overdamped Brownian particle moving in a symmetric periodic potential. We show that a net particle flow can be produced by adiabatically changing two external periodic potentials with a phase difference phi in time and chi in space. The classical pumped current is found to be independent of the friction and to vanish both in the limit of low and high temperature. Below a...
متن کاملNon-adiabatic pumping in classical and quantum chaotic scatterers
We study directed transport in periodically forced scattering systems in the regime of fast and strong driving where the dynamics is mixed to chaotic and adiabatic approximations do not apply. The model employed is a square potential well undergoing lateral oscillations, alternatively as twoor singleparameter driving. Mechanisms of directed transport are analyzed in terms of asymmetric irregula...
متن کاملNon-classical Role of Potential Energy in Adiabatic Quantum Annealing
Adiabatic quantum annealing is a paradigm of analog quantum computation, where a given computational job is converted to the task of finding the global minimum of some classical potential energy function and the search for the global potential minimum is performed by employing external kinetic quantum fluctuations and subsequent slow reduction (annealing) of them. In this method, the entire pot...
متن کاملClassical ratchet effects in heterostructures with a lateral periodic potential
We study terahertz radiation induced ratchet currents in low dimensional semiconductor structures with a superimposed one-dimensional lateral periodic potential. The periodic potential is produced by etching a grating into the sample surface or depositing metal stripes periodically on the sample top. Microscopically, the photocurrent generation is based on the combined action of the lateral per...
متن کاملTopological States and adiabatic pumping in quasicrystals.
The unrelated discoveries of quasicrystals and topological insulators have in turn challenged prevailing paradigms in condensed-matter physics. We find a surprising connection between quasicrystals and topological phases of matter: (i) quasicrystals exhibit nontrivial topological properties and (ii) these properties are attributed to dimensions higher than that of the quasicrystal. Specifically...
