Exact treatment of magnetism-driven ferroelectricity in the one-dimensional compass model
Wen-Long You, Guang-Hua Liu, Peter Horsch +1
We consider a class of one-dimensional compass models with antisymmetric Dzyaloshinskii-Moriya exchange interaction in an external magnetic field. Based on the exact solution deriv…
Giant magnetoresistance and spin Seebeck coefficient in zigzag a-graphyne nanoribbons
M. X. Zhai, X. F. Wang, P. Vasilopoulos +5
We investigate the spin-dependent electric and thermoelectric properties of ferromagnetic zigzag-graphyne nanoribbons (ZGNRs) using the density-functional theory combined with the…
Quantum phase transitions in exactly solvable one-dimensional compass models
Wen-Long You, Peter Horsch, Andrzej M. Oleś
We present an exact solution for a class of one-dimensional compass models which stand for interacting orbital degrees of freedom in a Mott insulator. By employing the Jordan-Wigne…
