N ov 2 00 1 Pairing in asymmetric two - component fermion matter

We analyze the possibilities of pairing between two different fermion species in asymmetric matter at low density. While the direct interaction allows pairing only for very small asymmetries, the pairing mediated by polarization effects is always possible, with a pronounced maximum at finite asymmetry. We present analytical results up to second order in the low-density parameter k F a.

We determine the influence of the three-body force and the medium modification of meson masses on pairing in nuclear and neutron matter. A reduction of the pairing gap is found and increasing with density. PACS: 21.65.+f, 24.10.Cn Typeset using REVTEX

Test-Takers’ Perceptions of Paired Speaking Tests and the Role of Interlocutor Variables in Pairing

As a mixed-method study, this study investigated EFL test-takers’ perceptions of paired speaking tests and the role of interlocutor variables (i.e., peer interlocutor’s acquaintanceship, gender, and proficiency level) in pairing in a Cambridge English Language Assessment Open Center. The participants (N = 148), having experienced sitting either live paired speaking tests of Cambridge E...

In this paper, we have studied tunneling effect of the spin-2 Bose condensate driven by external magnetic field. We find that the population transfers among spin-0 and spin-±1, spin-0 and spin-±2 exhibit the step structure under the external cosinusoidal magnetic field respectively , but there do not exist step structure among spin-±1 and spin-±2. The tunneling current among spin-±1 and spin-±2...
