Spin-glasses in optical cavity
Abstract. Recent advances in nanofabrication and optical control have garnered tremendous interest in multi-qubit-cavity systems. Here we analyze a spin-glass version of such a nanostructure, solving analytically for the phase diagrams in both the matter and radiation subsystems in the replica symmetric regime. Interestingly, the resulting phase transitions turn out to be tunable simply by vary...
متن کاملOptically controlled spin-glasses generated using multi-qubit cavity systems
Recent advances in nanofabrication and optical control imply that multi-qubit-cavity systems can now be engineered with pre-designed couplings. Here we propose optical realizations of spin-glass systems which exploit these new nanoscale technologies. By contrast with traditional realizations using magnetic solids, phase transition phenomena can now arise in both the matter and radiation subsyst...
متن کاملSpin Glasses
The understanding of random magnetic systems known as spin glass has been one of the major challenges in condensed matter physics over that past two decades. Study of this state can be thought of as a rst step towards understanding more complex and disordered systems.This paper reviews some of the theoretical developmets in this eld and tries to answer the question how well are these systems un...

متن کاملScaling in spin-glasses.
Many results of the mean-field theory of spin-glasses violate simple scaling laws, including the magnetic field dependence of the transition lines, crossover effects of random anisotropy, and critical behavior in the ordered phase. These violations arise from two dangerously irrelevant variables. Below eight dimensions some mean-field exponents change and at d = 6 scaling is restored. Below d =...
