Dependence of the thermally assisted spin torque switching probability on the sweep electric current was investigated theoretically. The analytical expressions of the switching times for b = 1 and b = 2 are derived based on the rate equation, where b is the exponent of the current term in the switching rate. The switching current is approximately proportional to the temperature T and the logari...

The thermodynamic Bethe ansatz method is employed for the study of the integrable critical RSOS(q1, q2; q) model. The high and low temperature behavior are investigated, and the central charge of the effective conformal field theory is derived. The obtained central charge is expressed as the sum of the central charges of two generalized coset models.

We give a complete description of the set of periodic Gibbs states at low temperatures for classical spin systems with arbitrary ferromagnetic, finite-range, interactions and fairly general even single-spin distribution of compact support on R. This extends results of Holsztynski and Slawny for the spin-l /2 case. The extension is based on recent ferromagnetic inequalities and low-temperature e...

An increasing number of enzymes active at low temperature are being studied to help determine the structural features important for cold-activity. This review examines the diversity of prokaryotic cold-active enzymes and the features proposed to account for low temperature activity. We then consider the difficulty of identifying the key structural features needed for cold-activity and the need ...

We report results of nonequilibrium molecular dynamics simulations of a one-component glassy system under the influence of a shear flow, with the aim of investigating shear-induced ordering of this system. In spite of the very low temperature, the system transforms into a strained crystalline state through well defined nucleation events. Various characteristics of the observed ordering at diffe...

The question concerning the possibility of a first order surface transition in a semi–infinite Blume–Capel model is addressed by means of low temperature expansions. It is found that such a transition can exist, according to mean field and cluster variation approximations, and contrarily to renormalization group results.

If weakly interacting massive.particles (WIMPS) are the dark matter in the galactic halo, they may be detected in low background ionization detectors now operating or with low temperature devices under development. In detecting WIMPS of low msss or WIMPS with spin-dependent nuclear interactions (e.g., photinos), a principal technical difficulty appears to be achieving very low thresholds (5 O(k...

Low-temperature specific heat measurements on the Heusler-type compounds Fe2VGa have been performed. We observed the sample-dependent upturn in C/T at low temperatures which is attributed to the effect of magnetic impurities and/or clusters. After subtracting this extrinsic effect, the resulting γ still indicated heavy fermion behavior with an effective mass of about 20 times larger than the va...
