Electronic structure and optical properties of ZnS/CdS nanoheterostructures
J. Perez-Conde, A. K. Bhattacharjee
The electronic and optical properties of spherical nanoheterostructures are studied within the semi-empirical tight-binding model including the spin-orbit interaction…
Functional Renormalization Group and the Field Theory of Disordered Elastic Systems
Pierre Le Doussal, Kay Joerg Wiese, Pascal Chauve
We study elastic systems such as interfaces or lattices, pinned by quenched disorder. To escape triviality as a result of ``dimensional reduction'', we use the functional renormali…
Phase Coherent Precessional Magnetization Reversal in Micro-scopic Spin Valve Elements
H. W. Schumacher, C. Chappert, P. Crozat +5
We study the precessional switching of the magnetization in microscopic spin valve cells induced by ultra short in-plane hard axis magnetic field pulses. Stable and highly efficien…
2-loop Functional Renormalization Group Theory of the Depinning Transition
Pierre Le Doussal, Kay Joerg Wiese, Pascal Chauve
We construct the field theory which describes the universal properties of the quasi-static isotropic depinning transition for interfaces and elastic periodic systems at zero temper…
New phasing method based on the principle of minimum charge
P. Kalugin
A new method of the phase determination in X-ray crystallography is proposed. The method is based on the so-called "minimum charge" principle, recently suggested by Elser. The elec…
Indivisibility of electron bubbles in helium
Veit Elser
A recent proposal by Maris[1], that single electron bubbles in helium might fission into separate, particle-like entities, does not properly take into account the failure of the ad…
