Effects of randomness on the critical temperature in quasi-two-dimensional organic superconductors
Enver Nakhmedov, Oktay Alekperov, Reinhold Oppermann
The effects of non-magnetic disorder on the critical temperature T_c of organic weak-linked layered superconductors with singlet in-plane pairing are considered. A randomness in th…
Disorder-driven superconductor-normal metal phase transition in quasi-one-dimensional organic conductors
E. Nakhmedov, R. Oppermann
Effects of non-magnetic disorder on the critical temperature T_c and on diamagnetism of quasi-one-dimensional superconductors are reported. The energy of Josephson-coupling between…
Critical disorder effects in Josephson-coupled quasi-one-dimensional superconductors
E. P. Nakhmedov, R. Oppermann
Effects of non-magnetic randomness on the critical temperature T_c and diamagnetism are studied in a class of quasi-one dimensional superconductors. The energy of Josephson-couplin…
Universality class of replica symmetry breaking, scaling behavior, and the low-temperature fixed-point order function of the Sherrington-Kirkpatrick model
Reinhold Oppermann, Manuel J. Schmidt
A scaling theory of replica symmetry breaking (RSB) in the SK-model is presented in the framework of critical phenomena for the scaling regime of small inverse RSB-orders, small te…
New technique for replica symmetry breaking with application to the SK-model at and near T=0
Manuel J. Schmidt, Reinhold Oppermann
We describe a novel method which allows the treatment of high orders of replica-symmetry-breaking (RSB) at low temperatures as well as at T=0 directly, without a need for approxima…
Construction and purpose of effective field theories for frustrated magnetic order
R. Oppermann, M. J. Schmidt
This article reviews recent years' progress in the low temperature analysis of standard models of spin glass order such as the Sherrington-Kirkpatrick (SK) model. Applications to C…
