Reiter's polaron wavefunction applied to a orbital t-J model
Krzysztof Wohlfeld, Andrzej M. Oles, Maria Daghofer +1
Using the self-consistent Born approximation we calculate Reiter's wavefunction for a single hole introduced into the undoped and orbitally ordered ground state of the t-J model wi…
Spectral properties of orbital polarons in Mott insulators
Krzysztof Wohlfeld, Maria Daghofer, Andrzej M. Oles +1
We address the spectral properties of Mott insulators with orbital degrees of freedom, and investigate cases where the orbital symmetry leads to Ising-like superexchange in the orb…
Superconductivity of Mo3Sb7 from first principles
Bartlomiej Wiendlocha, Janusz Tobola, Malgorzata Sternik +3
Superconductivity in Mo3Sb7 is analyzed using the combined electronic structure and phonon calculations, and the electron--phonon coupling constant λ_{ph}=0.54 is determined from f…
Thermally activated Peierls dimerization in ferromagnetic spin chains
J. Sirker, A. Herzog, A. M. Oles +1
We demonstrate that a Peierls dimerization can occur in ferromagnetic spin chains activated by thermal fluctuations. The dimer order parameter and entanglement measures are studied…
Quantum Phase Transition in the One-Dimensional XZ Model
Wojciech Brzezicki, Andrzej M. Oles
We introduce a one-dimensional (1D) XZ model with alternating and interactions on even/odd bonds, interpolating between the Ising model and the qu…
Evolution of Spin-Orbital-Lattice Coupling in the VO Perovskites
Peter Horsch, Andrzej M. Oles', Louis Felix Feiner +1
We introduce a microscopic model which unravels the physical mechanisms responsible for the observed phase diagram of the VO perovskites. It reveals a nontrivial interplay b…
