Supersymmetric Spin Glass [PDF]
The evidently supersymmetric four-dimensional Wess-Zumino model with quenched disorder is considered at the one-loop level. The infrared fixed points of a beta-function form the moduli space $M = RP^2$ where two types of phases were found: with and ...

We study the quenched complexity in spin-glass mean-field models satisfying the Becchi-Rouet-Stora-Tyutin supersymmetry. The outcome of such study, consistent with recent numerical results, allows, in principle, to conjecture the absence of any supersymmetric contribution to the complexity in the Sherrington-Kirkpatrick model.

Stationarization and Multithermalization in spin glasses [PDF]
We develop further the study of a system in contact with a multibath having different temperatures at widely separated timescales. We consider those systems that do not thermalize in finite times when in contact with an ordinary bath but may do so in contact with a multibath.

Spin-Glass Transition of the Three-Dimensional Heisenberg Spin Glass [PDF]
It is shown, by means of Monte Carlo simulation and Finite Size Scaling analysis, that the Heisenberg spin glass undergoes a finite-temperature phase transition in three dimensions. There is a single critical temperature, at which both a spin glass and a chiral glass orderings develop.

Reservoir computing is a brain heuristic computing paradigm that can complete training at a high speed. The learning performance of a reservoir computing system relies on its nonlinearity and short-term memory ability.

Recent work on the zero temperature phases and phase transitions of strongly random electronic system is reviewed. The transition between the spin glass and quantum paramagnet is examined, for both metallic and insulating systems. Insight gained from the solution of infinite range models leads to a quantum field theory for the transition between a ...

Frustration-Induced Relaxation in Polycrystalline Nd1- xSrxCoO3 (x=0.10, 0.15, 0.20)
This paper attempts to examine the details on the magnetic relaxation and aging effect of cobaltite Nd1- xSrxCoO3 (x=0.10, 0.15, 0.20). To this end, a series of polycrystalline Nd1-xSrxCoO3 samples were prepared in the traditional way, and their ...

Influence of Concentration Fluctuations on Relaxation Processes in Spin Glasses
Using the unique combination of atomically resolved atom probe tomography (APT) and volume averaged neutron (resonance) spin echo (NRSE and NSE) experiments, the influence of nano-scaled clusters on the spin relaxation in spin glasses was studied.
