Topological end state and enhanced thermoelectric performance of a supramolecular device
Wenlai Mu, Nisar Muhammad, Huaihong Guo +3
Supramolecular device (SMD) with topological end states and a noncovalent junction is rarely investigated but deemed promising for thermoelectric (TE) applications. We designed a n…
The action of the nearest neighbor Coulomb repulsion on the homogeneity in the high concentration domain for itinerant systems
Zsolt Gulacsi
Exact results are presented for itinerant systems demonstrating that the nearest neighbor Coulomb repulsion (V) destroys the homogeneity in the high concentration regime, this prop…
Spin-1/2 operators exactly mapped to spinful canonical Fermi operators present in two bands
Zsolt Gulacsi
Recently it has been shown that the quantum spin-1/2 spin operators can be exactly transformed not only in spinless, but also in spinful canonical Fermi operators in 1D [\cite{JW1}…
Jordan-Wigner transformation constructed for spinful fermions at spin-1/2 in two dimensions
Zsolt Gulacsi
Recently a Jordan-Wigner transformation was constructed for spinful fermions at S=1/2 spins in one dimension connecting the spin-1/2 operators to genuine spinful canonical Fermi op…
Jordan-Wigner transformation constructed for spinful fermions at S=1/2 spins in one dimension
Zsolt Gulacsi
An exact Jordan-Wigner type of transformation is presented in 1D connecting spin-1/2 operators to spinful canonical Fermi operators. The transformation contains two free parameters…
