Alpha-Particle Condensation in Nuclear Systems
The onset of quartetting, i.e. α-particle condensation, in symmetric nuclear matter is studied with the help of an in-medium modified four nucleon equation. It is found that at very low density quartetting wins over pairing, because of the strong binding of the α-particles. The critical temperature can reach values up to around 6 MeV. Also the disappearance of α-particles with increasing densit...
متن کاملAlpha-particle condensation in nuclei
A round up of the present status of the conjecture that nα nuclei form an αparticle condensate in excited states close to the nα threshold is given. Experiments which could demonstrate the condensate character are proposed. Possible lines of further theoretical developments are discussed. In this article we want to report on the present status of our recent conjecture [1] that at least light nα...
متن کاملAggregation, condensation and coagulation in particle systems
John Cardy (Oxford) Mon 13:00 Random Curves in 2d and Diffusion-Aggregation Processes in 1d In recent years the theory of Schramm-Loewner Evolution (SLE) has been developed to describe the growth of a single random curve γ into a simply-connected domain D of the plane, starting at a point on its boundary. It uses a conformal mapping gt : D \ γt → D which sends the growing tip of the curve to a ...
متن کاملParticle Production in Tachyon Condensation
We study particle production in the tachyon condensation process as described by different effective actions for the tachyon. By making use of invariant operators, we are able to obtain exact results for the density of produced particles, which is shown to depend strongly on the specific action. In particular, the rate of particle production remains finite only for one of the actions considered...
متن کاملKaon Condensation in “Nuclear Star” Matter
The critical density for kaon condensation in “nuclear star” matter is computed up to two-loop order in medium (corresponding to next-to-next-to-leading order in chiral perturbation theory in free space) with a heavy-baryon effective chiral Lagrangian whose parameters are determined from KN scattering and kaonic atom data. To the order considered, the kaon self-energy has highly non-linear dens...
