Two-dimensional bose gas range cross thermodynamics parameters superfluids
2014/12/22
We study the crossover between the mean-field and critical behavior of the two-dimensional Bose gas throughout the fluctuation region of the Berezinskii-Kosterlitz-Thouless phase transition point. We ...
Quantum-fluctuation effects in transport properties of superconductors above the paramagnetic limit
Quantum-fluctuation effects transport properties superconductors the paramagnetic limit
2012/2/27
We study the transport in ultrathin disordered film near the quantum critical point induced by the Zeeman field. We calculate corrections to the normal state conductivity due to quantum pairing fluctu...

Brightness Fluctuation Mid-Infrared Sky AKARI Observations the North Ecliptic Pole
2012/2/21
We present the smoothness of the mid-infrared sky from observations by the Japanese infrared astronomical satellite AKARI. AKARI monitored the north ecliptic pole (NEP) during its cold phase with nine...
Fluctuation bounds in the exponential bricklayers process
Interacting particle systems universal fluctuation bounds second class particle convexity bricklayers process
2011/9/20
Abstract: This paper is the continuation of our earlier paper, where we proved t^{1/3}-order of current fluctuations across the characteristics in a class of one dimensional interacting systems with o...

Abstract: In this paper we present an extended version of Hilbert-Huang transform, namely arbitrary-order Hilbert spectral analysis, to characterize the scale-invariant properties of a time series dir...
Quantum Origin of the Primordial Fluctuation Spectrum and its Statistics
Quantum Origin Primordial Fluctuation Spectrum Statistics
2011/10/9
The account of the origin of cosmic structure, as provided by the standard inflationary paradigm, is not fully satisfactory, as has been argued in Perez et al 2006. The central point of that work is t...
