Electronic model for superconductivity [PDF]
Physical Review Letters, 1993 We consider a model of strongly correlated electrons that exhibits supcrconductivity. It differs from the Hubbard model by nearest-neighbor interactions. We find the ground-state wave function (in one, two, or three dimensions) and show it to be superconducting for attractive and moderately repulsive on-site ...

Common mechanisms of attractorless oscillatory regimes in radioengineering models of brain thalamocortical network [PDF]
Известия высших учебных заведений: Прикладная нелинейная динамика, 2021 This work aims to show that long transient processes in mesascale models of thalamocortical brain network can appear in very general case, in particular for different number of elements in the ensemble (different level of detalization) and different ...

Diode-pumped wavelength-switchable visible Pr3+:YLF laser and vortex laser around 670 nm
Opto-Electronic Advances, 2021 Here we developed a novel wavelength-switchable visible continuous-wave (CW) Pr3+:YLF laser around 670 nm. In single-wavelength laser operations, the maximum output powers of 2.60 W, 1.26 W, and 0.21 W, the maximum slope efficiencies of 34.7%, 27.3%, and

CHAPLYGIN ELECTRON GAS MODEL [PDF]
International Journal of Modern Physics D, 2009 We provide a new electromagnetic mass model admitting the Chaplygin gas equation of state. We investigate three specializations, the first characterized by a vanishing effective pressure, the second provided with a constant effective density and the third described by a constant effective pressure p0.
