... mechanism for the escape rate, and hence for SR itself, is strongly dependent on temperature ~see Fig. 2!. Prior studies @22,23# on the effects of quantum noise on SR addressed the regime of very low temperatures T!T 0 , where thermal hopping events can be neglected. The focus of this work is on the ...

... models, since it seems clear that they cannot be physically implemented. It had been argued that the Turing machine model is the inevitable choice once we assume that we can implement only finite precision computational primitives. Given the widespread belief that NP 6= BPP, this would seem to put a ...

The states on opposite sides of the critical point are characterized by different types of ordering, typically from a symmetric or disordered state, which incorporates some symmetry of the Hamiltonian, to a brokensymmetry or ordered state, which does not have that symmetry, although ...
