Effects of external radiation on biased Aharonov-Bohm rings
O. Entin-Wohlman, Y. Imry, A. Aharony
We consider the currents flowing in a solid-state interferometer under the effect of both an Aharonov-Bohm phase and a bias potential. Expressions are obtained for these currents,…
Landau Expansion for the Kugel-Khomskii Hamiltonian
A. B. Harris, Amnon Aharony, O. Entin-Wohlman +2
The Kugel-Khomskii (KK) Hamiltonian for the titanates describes spin and orbital superexchange interactions between ions in an ideal perovskite structure in which the three $…
Adiabatic Quantum Pumping of Coherent Electrons
Ora Entin-Wohlman, Amnon Aharony, Vyacheslavs Kashcheyevs
We review recent theoretical calculations of charge transfer through mesoscopic devices in response to slowly-oscillating, spatially-confined, potentials. The discussion is restric…
Phase measurements in Aharonov-Bohm interferometers
Amnon Aharony, Ora Entin-Wohlman, Yoseph Imry
In this paper we address measurements of the resonant quantum transmission amplitude through a quantum dot (QD), as function of the plunger gate volt…
Resonance approximation and charge loading/unloading in adiabatic quantum pumping
Vyacheslavs Kashcheyevs, Amnon Aharony, Ora Entin-Wohlman
Quantum pumping through mesoscopic quantum dots is known to be enhanced by resonant transmission. The pumped charge is close to an integer number of electrons when the pumping cont…
Hidden Symmetries and their Consequences in Cubic Perovskites
A. B. Harris, T. Yildirim, A. Aharony +2
The five-band Hubbard model for a band with one electron per site is a model which has very interesting properties when the relevant ions are located at sites with high (e. g.…
Unusual Symmetries in the Kugel-Khomskii Hamiltonian
A. B. Harris, Taner Yildirim, Amnon Aharony +2
The Kugel-Khomskii Hamiltonian for cubic titanates describes spin and orbital superexchange interactions between ions having three-fold degenerate orbitals. Since or…
Anomalous diffusion at percolation threshold in high dimensions on 10^18 sites
Dirk Osterkamp, Dietrich Stauffer, Amnon Aharony
Using an inverse of the standard linear congruential random number generator, large randomly occupied lattices can be visited by a random walker without having to determine the occ…
Damped orbital excitations in the titanates
K. Kikoin, O. Entin-Wohlman, V. Fleurov +1
A possible mechanism for the removal of the orbital degeneracy in RTiO3 (where R=La, Y, ...) is considered. The calculation is based on the Kugel-Khomskii Hamiltonian for electrons…
Persistent currents in interacting Aharonov-Bohm interferometers and their enhancement by acoustic radiation
O. Entin-Wohlman, Y. Imry, A. Aharony
We consider an Aharonov-Bohm interferometer, connected to two electronic reservoirs, with a quantum dot embedded on one of its arms. We find a general expression for the persistent…
Efficient Hopfield pattern recognition on a scale-free neural network
Dietrich Stauffer, Amnon Aharony, Luciano da Fontoura Costa +1
Neural networks are supposed to recognise blurred images (or patterns) of pixels (bits) each. Application of the network to an initial blurred version of one of pre-assigne…
