Considering the low-temperature and high-baryon-number-density region of the QCD phase diagram, we present a model for the first-order phase transition between the quark-gluon plasma and the recently proposed colour su-perconducting phase. Numerical results for the activation energy and other physical parameters of the droplets of Cooper pairs, at various(More)
We consider a small and fixed number of fermions (bosons) in a trap. The ground state of the system is defined at T = 0. For a given excitation energy, there are several ways of exciting the particles from this ground state. We formulate a method for calculating the number fluctuation in the ground state using microcanonical counting, and implement it for(More)
We use the collective field theory known for the Calogero-Sutherland model to study a variety of low-energy properties. These include the ground state energy in a confining potential upto the two leading orders in the particle number, the dispersion relation of sound modes with a comparison to the two leading terms in the low temperature specific heat,(More)
We consider N particles interacting pair-wise by an inverse square potential in one dimension (Calogero-Sutherland-Moser model). When trapped harmonically, its classical canonical partition function for the repulsive regime is known in the literature. We start by presenting a concise re-derivation of this result. The equation of state is then calculated(More)
