Composite fermion-boson mapping for fermionic lattice models
Jinmo Zhao, Carlos A. Jimenez-Hoyos, Gustavo E. Scuseria +4
We present a mapping of elementary fermion operators onto a quadratic form of composite fermionic and bosonic operators. The mapping is an exact isomorphism as long as the physical…
Exactly solvable pairing Hamiltonian for heavy nuclei
J. Dukelsky, S. Lerma H., L. M. Robledo +2
We present a new exactly solvable Hamiltonian with a separable pairing interaction and non-degenerate single-particle energies. It is derived from the hyperbolic family of Richards…
Existence of Density Functionals for Excited States and Resonances
B. G. Giraud, K. Kato, A. Ohnishi +1
We show how every bound state of a finite system of identical fermions, whether a ground state or an excited one, defines a density functional. Degeneracies created by a symmetry g…
Integrable models for asymmetric Fermi superfluids: Emergence of a new exotic pairing phase
J. Dukelsky, G. Ortiz, S. M. A. Rombouts +1
We introduce an exactly-solvable model to study the competition between the Larkin-Ovchinnikov-Fulde-Ferrell (LOFF) and breached-pair superfluid in strongly interacting ultracold a…
