Thermal conductivity of solid parahydrogen with methane admixtures
A. I. Krivchikov, V. V. Sumarokov, J. Mucha +3
The thermal conductivity of solid parahydrogen crystal with methane admixtures has been measured in the temperature range 1.5 to 8 K. Solid samples were grown from the gas mixture…
SO(5) superconductor in a Zeeman magnetic field: Phase diagram and thermodynamic properties
T. A. Zaleski, T. K. Kopec
In this paper we present calculations of the SO(5) quantum rotor theory of high-T superconductivity in Zeeman magnetic field. We use the spherical approach for five-component…
Magnetic flux penetration and motion in antiferromagnetic superconductors
Tomasz Krzyszton
The paper reviews a concept of induced spin-flop domain inside vortices in an antiferromagnetic superconductor. Such phenomenon may occur when an external magnetic field is strong…
Electron momentum density in Cu0.9Al0.1
M. Samsel-Czekala, G. Kontrym-Sznajd, G. Doring +5
A reconstruction technique based on the solution of the Radon transform in terms of Jacobi polynomials is used to obtain the 3D electron momentum density rho(p) from nine high-reso…
Electron momentum density in yttrium
G. Kontrym-Sznajd, M. Samsel-Czekala, A. Pietraszko +7
A simultaneous analysis of high-resolution directional Compton profiles and two-dimensional angular correlation of positron annihilation experimental data has been performed by stu…
Special directions in the Brillouin zone
G. Kontrym-Sznajd, A. Jura, M. Samsel-Czekala
Rules are given for determining special directions in the Brillouin zone which optimize the descrip-tion of various physical quantities with Gamma1 type symmetry. We consider the c…
Fermi surface nesting and magnetic structure of ErGa3
M. Biasini, G. Ferro, G. Kontrym-Sznajd +1
A three dimensional mapping of the Fermi Surface (FS) of the rare-earth compound ErGa3 was determined via measurements of the angular correlation of the electron-positron annihilat…
Kinetic energy driven superconductivity and pseugogap phase in weakly doped antiferromagnets
P. Wrobel, R. Eder, R. Micnas
We derive an effective Hamiltonian for spin polarons forming in weakly doped antiferromagnets and demonstrate that the system becomes superconducting at finite doping. We argue tha…
Improvement of experimental data via consistency conditions
G. Kontrym-Sznajd
Interdependencies between experimental spectra, representing line or plane projections of electronic densities, are derived from their consistency and symmetry conditions. Some add…
Stripe phases in the two-dimensional Falicov-Kimball model
R. Lemanski, J. K. Freericks, G. Banach
The observation of charge stripe order in the doped nickelate and cuprate materials has motivated much theoretical effort to understand the underlying mechanism of the stripe phase…
Reconstructed Momentum Density and Fermi Surface in Cu0.9Al0.1
M. Samsel-Czekala, G. Kontrym-Sznajd, G. Doring +5
A reconstruction technique based on Radon transforms is used to obtain 3D electron momentum density rho(p) using nine recently measured high-resolution Compton profiles (CPs) from…
Fermi surface of Mg and Cd
A. Jura, G. Kontrym-Sznajd, M. Samsel-Czekala
We present three-dimensional (3D) electron-positron momentum densities in Mg and Cd, reconstructed from 2D angular correlation of annihilation radiation data. By folding densities…
A positron study of the Fermi surface of TmGa3
M. Biasini, A. Czopnik, A. Jura +2
For a single crystal of TmGa3, two-dimensional angular correlation of positron annihilation radiation spectra were measured and subjected to a deconvolution algorithm based on the…
Reptation in the Rubinstein-Duke model: the influence of end-reptons dynamics
Enrico Carlon, Andrzej Drzewinski, J. M. J. van Leeuwen
We investigate the Rubinstein-Duke model for polymer reptation by means of density-matrix renormalization group techniques both in absence and presence of a driving field. In the f…
