We present a study of the electrical and thermal conductivities of the d-density wave (DDW) state in an external magnetic field B in the low temperature regime and in the presence of impurities. We show that in the zero temperature limit, T → 0, the Wiedemann-Franz (WF) law remains intact. For finite T the WF law violation is possible and it is enhanced by the external field.

The temperature dependence of the static dielectric susceptibility of a system with strongly coupled fluctuating dipoles is calculated within a self-consistent mean fluctuation field approximation. Results are qualitatively in good agreement with a quantum paraelectric SrTiO(3) in the low temperature regime. We identify this system as a gapped quantum paraelectric and suggest a possible experim...

We fit finite-temperature path integral Monte Carlo calculations of the exchange-correlation energy of the 3D finite-temperature homogeneous electron gas in the warm-dense regime [rs ≡ (3/4πn)1/3a−1 B < 40 and ≡ T/TF > 0.0625]. In doing so, we construct a Padé approximant which collapses to Debye-Hückel theory in the high-temperature, low-density limit. Likewise, the zero-temperature limit matc...

Comprehensive no-go theorems show that information encoded over local two-dimensional topologically ordered systems cannot support macroscopic energy barriers, and hence will not maintain stable quantum information at finite temperatures for macroscopic time scales. However, it is still well motivated to study low-dimensional quantum memories due to their experimental amenability. Here we intro...

This paper presents piezoelectric transduction and frequency trimming of silicon-based resonators with a center frequency in the low megahertz regime. The temperature coefficient of frequency (TCF) of the resonators is reduced using both passive and active compensation schemes. Specifically, a novel technique utilizing oxide-refilled trenches is implemented to achieve efficient temperature comp...

We describe a powerful method for determining the equation of state of an ultracold gas from in situ images. The method provides a measurement of the local pressure of an harmonically trapped gas and we give several applications to Bose and Fermi gases. We obtain the grand-canonical equation of state of a spin-balanced Fermi gas with resonant interactions as a function of temperature [1]. We co...

The phase structure of a single self-interacting homopolymer chain is investigated in terms of a universal theoretical model, designed to describe the chain in the infrared limit of slow spatial variations. The effects of chirality are studied and compared with the influence of a short-range attractive interaction between monomers, at various ambient temperature values. In the high-temperature ...

We perform an extensive theoretical analysis of 10C nucleus with the use various approaches involving different nuclear potentials and density distributions, as well a simple cluster approach. try to explain new measured challenging experimental data on + 58Ni system at 35.3 MeV. First, we investigate effect thirteen potentials. Then, examine ten types distributions for nucleus. Finally, presen...

Determining which small exoplanets have stony-iron compositions is necessary for quantifying the occurrence of such planets and for understanding the physics of planet formation. Kepler-10 hosts the stony-iron world Kepler10b, and also contains what has been reported to be the largest solid silicate-ice planet, Kepler-10c. Using 220 radial velocities (RVs), including 72 precise RVs from Keck-HI...

The isotropic rigid and non-rigid rotators in the framework of Tsallis statistics are studied in the high and low temperature limits. The generalized partition functions, internal energies and heat capacities are calculated. Classical results of the Boltzmann-Gibbs statistics have been recovered as non-extensivity parameter approaches to 1. It has also been observed that non-extensivity paramet...
