Electron coherent and incoherent pairing instabilities in inhomogeneous bipartite and nonbipartite nanoclusters
A. N. Kocharian, G. W. Fernando, K. Palandage +1
Exact calculations of collective excitations and charge/spin (pseudo)gaps in an ensemble of bipartite and nonbipartite clusters yield level crossing degeneracies, spin-charge separ…
Novel insights into charge and spin pairing instabilities in nanoclusters
A. N. Kocharian, G. W. Fernando, K. Palandage +1
Electron pairing and ferromagnetism in various cluster geometries are studied with emphasis on tetrahedron and square pyramid under variation of interaction strength, electron dopi…
Exact Thermodynamics of Pairing and Charge-spin Separation Crossovers in Small Hubbard Nanoclusters
A. N. Kocharian, G. W. Fernando, T. Wang +2
The exact numerical diagonalization and thermodynamics in an ensemble of small Hubbard clusters in the ground state and finite temperatures reveal intriguing insights into the nasc…
