Topological Hall effect induced by classical large-spin background: $s u (2)$ path-integral approach

Kaushal K. Kesharpu, Evgenii A. Kochetov, Alvaro Ferraz

The $s u (2)$ coherent-state path-integral technique is employed to study lattice electrons strongly coupled to a quantum spin background. In the large-spin limit it is replaced with…

Spin-flip induced superfluidity in a ring of spinful hard-core bosons

K. K. Kesharpu, E. A. Kochetov

The t - J Hamiltonian of the spinful hard-core bosonic ring in the Nagaoka limit is solved. The energy spectrum becomes quantized due to presence of spin, where each energy level c…
