BCS-to-BEC crossover from the exact BCS solution
The BCS-to-BEC crossover, as well as the nature of Cooper pairs, in superconducting and Fermi superfluid media is studied from the exact ground state wave function of the reduced BCS Hamiltonian. As the strength of the interaction increases, the ground state continuously evolves from a mixed system of quasifree fermions and pair resonances BCS , to pair resonances and quasibound molecules pseud...
متن کاملBCS Pairing Dynamics
Experimental control over inter-atomic interactions by adjusting external parameters is discussed. Qualitatively different time evolution of the order parameter are predicted theoretically in ultracold atomic fermions with time-dependent pairing interaction. Following an abrupt change of the pairing strength, the order parameter undergoes undamped oscillation, damping oscillation and exponentia...
متن کاملBCS The Weakest Precondition
An extension of Dijkstra's guarded command language is studied, including unbounded demonic choice and a backtrack operator. We consider three orderings on this language: a reenement ordering deened by Back, a new deadlock ordering, and an approximation ordering of Nelson. The deadlock ordering is in between the two other orderings. All operators are monotonic in the Nelson ordering, but backtr...
متن کاملThe Emergence of BCS
Major contributions in theoretical physics do not emerge in a vacuum. They usually are inspired by experiment, require near total immersion in the relevant theoretical and experimental literature, and are often preceded by years of preliminary work, including the publication of failed or incomplete attempts at producing a theory, while recognition of their success does not always come instantly...
متن کاملA Better BCS
Most NCAA football teams never play each other in a given season, which has made ranking them a long-running and much-debated problem. The official Bowl Championship Series (BCS) standings are determined in equal parts by input from coaches, sports writers, and an average of algorithmic rankings. These standing determine which teams play for the national championship, and, in part, which teams ...
