Spin susceptibility and magnetic short-range order in the Hubbard model. [PDF]
Physical Review B (Condensed Matter), 1996 The uniform static spin susceptibility in the paraphase of the one-band Hubbard model is calculated within a theory of magnetic short-range order (SRO) which extends the four-field slave-boson functional-integral approach by the transformation to an ...

Proton spin dynamics in polymer melts: New perspectives for experimental investigations of polymer dynamics [PDF]
, 2014 The proton spin dynamics in polymer melts is determined by intramolecular and intermolecular magnetic dipole-dipole interactions among the proton spins.

Thermal diffusion of sine-Gordon solitons [PDF]
, 2000 :We analyze the diffusive motion of kink solitons governed by the thermal sine-Gordon equation. We analytically calculate the correlation function of the position of the kink center as well as the diffusion coefficient, both up to second-order in ...

Modeling Viscosity of Volcanic Melts With Artificial Neural Networks
Geochemistry, Geophysics, Geosystems, 2022 Viscosity is of great importance in governing the dynamics of volcanoes, including their eruptive style. The viscosity of a volcanic melt is dominated by temperature and chemical composition, both oxides and water content.

Theory of magnetic short-range order for itinerant electron systems [PDF]
, 1996 On the basis of the one-band t–t′-Hubbard model a self-consistent renormalization theory of magnetic short-range order (SRO) in the paramagnetic phase is presented combining the four-field slave-boson functional-integral scheme with the cluster ...

Theory of magnetic short-range order for high-Tc superconductors [PDF]
, 1996 A theory of magnetic short-range order for high- T c cuprates is presented on the basis of the one-band t − t ′-Hubbard model combining the four-field slave-boson functional integral technique with the Bethe cluster method.

Magnetic properties of the 2D t-t′-Hubbard model [PDF]
, 1996 The two-dimensional (2D) t-t′-Hubbard model is studied within the slave-boson (SB) theory. At half-filling, a paramagnetic to antiferromagnetic phase transition of first order at a finite critical interaction strength Uc(t′/t) is found. The dependence on
