Molecular structure in biomolecular condensates

Structure of Vacuum Condensates

It is essential to know the space-time structure of the nonlocal vacuum condensates for application to medium energy processes. Using the DysonSchwinger formalism in the rainbow approximation for the quark propagator, we study the nonlocal quark condensate and model forms for the nonperturbative gluon propagator constrained by fits to local condensates and deep inelastic scattering with nucleon...

Vortices in atomic-molecular Bose–Einstein condensates

The structure and stability of vortices in hybrid atomic-molecular Bose–Einstein condensates is analysed in the framework of a two-component Gross–Pitaevskii-type model that describes the stimulated Raman-induced photoassociation process. New types of topological vortex states are predicted to exist in the coherently coupled two-component condensates even without a trap, and their nontrivial dy...

Atomic-molecular Bose-Einstein condensates

The study of coupled atomic-molecular Bose-Einstein condensates is currently an active research topic in the field of ultracold quantum gases. Our calculations here are potentially relevant to future Rubidium dimer experiments that could be carried out at either the SUT or ANU nodes of ACQAO. We also aim to model recent experiments on dissociation of 87Rb2 dimers in the group of G. Rempe at the...

Coherent Molecular Solitons in Bose-Einstein Condensates

We analyze the coherent formation of molecular Bose-Einstein condensate (BEC) from an atomic BEC, using a parametric field theory approach. We point out the transition between a quantum soliton regime, where atoms couple in a local way to a classical soliton domain, where a stable coupledcondensate soliton can form in three dimensions. This gives the possibility of an intense, stable atomlaser ...
