Phase Transition Study of Superconducting Microstructures
C. Berger
The presented results are part of a feasibility study of superheated superconducting microstructure detectors. The microstructures (dots) were fabricated using thin film patterning…
Singular Traces and Compact Operators. I
S. Albeverio, D. Guido, A. Ponosov +1
We give a necessary and sufficient condition on a positive compact operator for the existence of a singular trace (i.e. a trace vanishing on the finite rank operators) which ta…
Fermionic effective action and the pahse estructure of non compact quantum electrodynamics in 2+1 dimensions
V. Azcoiti, X. Q. Luo, C. E. Piedrafita +3
We study the phase diagram of non compact using the microcanonical fermionic average method described elsewhere. We present evidence for a continuous phase transition line…
Lack of self-average in weakly disordered one dimensional systems
A. Crisanti, G. Paladin, M. Serva +1
We introduce a one dimensional disordered Ising model which at zero temperature is characterized by a non-trivial, non-self-averaging, overlap probability distribution when the imp…
Products of Random Matrices for Disordered Systems
A Crisanti, G Paladin, M Serva +1
Products of random transfer matrices are applied to low dimensional disordered systems to evaluate numerically extensive quantities such as entropy and overlap probability distribu…
