Alternative equation of motion approach applied to transport through a Quantum Dot
Grzegorz Górski, Jerzy Mizia, Krzysztof Kucab
We study non-equilibrium electron transport through a quantum dot coupled to metallic leads. We use an alternative equation of motion approach in which we calculate the retarded Gr…
Energy harvesting in the nonlinear piezoelastic systems driven by stochastic excitations
K. Kucab, G. Górski, J. Mizia
In our work we examine the influence of background stochastic excitations on the power output generated by the energy harvester. The harvesting device we considered is composed of…
Phase separation near half-filling point in superconducting compounds
K. Kucab, G. Górski, J. Mizia
We present the model of superconducting ceramics using the single band extended Hubbard Hamiltonian. We investigate the simultaneous presence of antiferromagnetism (AF) and d-wave…
Band magnetism with inter-site correlations and interactions
J. Mizia, G. Górski, K. Kucab
We introduce the Hamiltonian to describe narrow band electrons. The physics of driving forces towards ferromagnetism is re-examined. Using different approximations it has been show…
Alternative equation of motion approach to the single-impurity Anderson model
Grzegorz Górski, Jerzy Mizia, Krzysztof Kucab
Solving the single-impurity Anderson model (SIAM) is a basic problem of solid state physics. The SIAM model is very important, at present it is also used for systems with quantum i…
New Green function approach describing the ferromagnetic state in the simple Hubbard model
Grzegorz Górski, Jerzy Mizia, Krzysztof Kucab
We consider a Hubbard model with occupation dependent hopping integrals. Using the Hartree-Fock (H-F) approximation and the new Green function approach with inter-site kinetic aver…
