The BCS gap equation for spin-polarized fermions
The BCS gap equation spin-polarized fermions Quantum Gases
2011/8/23
Abstract: We study the BCS gap equation for a Fermi gas with unequal population of spin-up and spin-down states. For $\cosh(\delta_\mu/T) \leq 2$, with $T$ the temperature and $\delta_\mu$ the chemica...
Rapidly fluctuating orbital occupancy above the orbital ordering transition in spin-gap compounds
Rapidly fluctuating orbital orbital ordering spin-gap compounds
2010/11/19
Several spin systems with low dimensionality develop a spin-dimer phase within a molecular orbital below TS, competing with long-range antiferromagnetic order. Very often, preferential orbital occupan...
