Correlations of self-bound identical fermions

Identical Particle Correlations in STAR 3

Preliminary results of identical-particle correlations probing the geometric substructure of the particle-emitting source at RHIC are presented. An m T-independent scaling of pion HBT radii from large (central Au+Au) to small (p+p) collision systems naively suggests comparable flow strength in all of them. Multidimensional correlation functions are studied in detail using a spherical decomposit...

Self-consistent model of fermions

Abstract: A composite model of fermions based on three-flavoured preons is presented. It is shown that the opposite character of interactions between preons leads to formation of complex structures reproducing three generations of quarks and leptons with all their quantum numbers and masses. The model is self-consistent (it doesn’t use input parameters). Nevertheless, the masses of the generate...

Decoherence of quantum kinematical correlations: Elastic scattering of identical particles

Detection of spatial correlations in an ultracold gas of fermions.

Spatial correlations are observed in an ultracold gas of fermionic atoms close to a Feshbach resonance. The correlations are detected by inducing spin-changing rf transitions between pairs of atoms. We observe the process in the strongly interacting regime for attractive as well as for repulsive atom-atom interactions and both in the regime of high and low quantum degeneracy. The observations a...

Superfluidity and binary-correlations within clusters of fermions

We propose a method for simulating the behaviour of small clusters of particles that explicitly accounts for all mean-field and binary-correlation effects. Our approach leads to a set of variational equations that can be used to study both the dynamics and thermodynamics of these clusters. As an illustration of this method, we explore the BCS-BEC crossover in the simple model of four fermions, ...
