ac-driven atomic quantum motor.
We propose an ac-driven quantum motor consisting of two different, interacting ultracold atoms placed into a ring-shaped optical lattice and submerged in a pulsating magnetic field. While the first atom carries a current, the second one serves as a quantum starter. For fixed zero-momentum initial conditions the asymptotic carrier velocity converges to a unique nonzero value. We also demonstrate...

متن کاملAC-driven quantum spins: resonant enhancement of transverse DC magnetization
Magnetic resonance effects have been long studied and used for various spectroscopic methods1–3. Timedependent external fields being an integral part of the physical setups, become also very interesting in their action when entering the field of spintronics and processing of quantum information. While the linear response of a system (probe) to external fields may be typically understood in a ra...
متن کاملDynamical control of electronic states in AC-Driven Quantum Dots
We investigate the dynamics of two interacting electrons moving in a one-dimensional array of quantum dots under the influence of an ac field. The quantum dot array is modeled as a single-band tight-binding model of Hubbard type and its dynamics is analyzed by means of the Floquet approach which has been shown to be very accurate for describing the dynamics of interacting electrons in single[1]...
متن کاملac-driven localization in a two-electron quantum dot molecule
We investigate the dynamics of two interacting electrons confined to a pair of coupled quantum dots driven by an external ac field. By numerically integrating the two-electron Schrödinger equation in time, we find that for certain values of the strength and frequency of the ac field the electrons can become localized within just one of the dots, in spite of the Coulomb repulsion. Reducing the s...
