Fano resonance in discrete lattice models: controlling lineshapes with impurities

Arunava Chakrabarti

The possibility of controlling Fano lineshapes in the electronic transmission is addressed in terms of a simple discrete model within a tight binding framework, in which a finite s…

Vortex lattices in Bose-Einstein condensates with Dipolar Interactions Beyond the Weak Interaction Limit

S. Komineas, N. R. Cooper

We study the ground states of rotating atomic Bose-Einstein condensates with dipolar interactions. We present the results of numerical studies on a periodic geometry which show vor…

Bound states in the continuum in open Aharonov-Bohm rings

Evgeny N. Bulgakov, Konstantin N. Pichugin, Almas F. Sadreev +1

Using formalism of effective Hamiltonian we consider bound states in continuum (BIC). They are those eigen states of non-hermitian effective Hamiltonian which have real eigen value…

Effect of magnetic pair breaking on Andreev bound states and resonant supercurrent in quantum dot Josephson junctions

Grygoriy Tkachov, Klaus Richter

We propose a model for resonant Josephson tunneling through quantum dots that accounts for Cooper pair-breaking processes in the superconducting leads caused by a magnetic field or…

Optimization of soliton ratchets in inhomogeneous sine-Gordon systems

F. G. Mertens, L. Morales-Molina, A. R. Bishop +2

Unidirectional motion of solitons can take place, although the applied force has zero average in time, when the spatial symmetry is broken by introducing a potential , which…
