Isotope effect in impure high T_c superconductors

open access: yes, 2003
The influence of various kinds of impurities on the isotope shift exponent \alpha of high temperature superconductors has been studied. In these materials the dopant impurities, like Sr in La_{2-x}Sr_xCuO_4, play different role and usually occupy ...

Lorentz's model with dissipative collisions

open access: yes, 1998
Propagation of a particle accelerated by an external field through a scattering medium is studied within the generalized Lorentz model allowing inelastic collisions. Energy losses at collisions are proportional to $(1-\alpha^{2})$, where $0\le\alpha\le 1$

Haldane exclusion statistics and second virial coefficient

open access: yes, 1994
We show that Haldanes new definition of statistics, when generalised to infinite dimensional Hilbert spaces, is equal to the high temperature limit of the second virial coefficient.

Parametric inference for discretely observed multidimensional diffusions with small diffusion coefficient

open access: yes, 2012
We consider a multidimensional diffusion X with drift coefficient b({\alpha},X(t)) and diffusion coefficient {\epsilon}{\sigma}({\beta},X(t)). The diffusion is discretely observed at times t_k=k{\Delta} for k=1..n on a fixed interval [0,T].

The Oberbeck--Boussinesq Approximation as a Constitutive Limit

open access: yes, 2015
We derive the usual Oberbeck--Boussinesq approximation as a constitutive limit of the full system describing the motion of an compressible linearly viscous fluid. To this end the starting system is written, using the Gibbs free energy, in the variables $\
