Mechanism and Kinetics of Na+ Ion Depletion under the Anode during Electro-thermal Poling of a Bioactive Glass
C. R. Mariappan, B. Roling
Electro-thermal poling experiments were carried out on a bioactive glass, and the kinetics of the Na+ ion depletion layer formation under the anode was studied in-situ by means of…
Hopping conduction in strong electric fields: Negative differential conductivity
A. V. Nenashev, F. Jansson, S. D. Baranovskii +3
Effects of strong electric fields on hopping conductivity are studied theoretically. Monte-Carlo computer simulations show that the analytical theory of Nguyen and Shklovskii [Soli…
Frustrated three-leg spin tubes: from spin 1/2 with chirality to spin 3/2
J. -B. Fouet, A. Laeuchli, S. Pilgram +2
Motivated by the recent discovery of the spin tube [(CuCltachH)Cl]Cl, we investigate the properties of a frustrated three-leg spin tube with antiferromagnetic intra-rin…
Unusual quasi-one-dimensional electron dispersions in the spin-1/2 quantum magnet TiOCl
M. Hoinkis, M. Sing, J. Schaefer +8
We have studied the electronic structure of the spin-1/2 quantum magnet TiOCl by polarization-dependent momentum-resolved photoelectron spectroscopy. From that, we confirm the quas…
Tomonaga-Luttinger parameters for doped Mott insulators
Satoshi Ejima, Florian Gebhard, Satoshi Nishimoto
The Tomonaga--Luttinger parameter determines the critical behavior in quasi one-dimensional correlated electron systems, e.g., the exponent for the density of states near…
Microscopic analysis of the coherent optical generation and the decay of charge and spin currents in semiconductor heterostructures
Huynh Thanh Duc, T. Meier, S. W. Koch
The coherent optical injection and temporal decay of spin and charge currents in semiconductor heterostructures is described microscopically, including excitonic effects, carrier L…
