We investigate the continuum limit scaling of the scalar condensate in the N f = 2 Schwinger model on the lattice. We employ maximally twisted mass Wilson fermions and overlap fermions. We compute the scalar condensate by taking the trace of the propagator (direct method) and by utilizing the integrated Ward-Takahashi identity. While the scalar condensate comes out consistent using these two me...

Motivated by the recent realization of a Cr Bose-Einstein condensate, we consider the phase diagram of a general spin-three condensate as a function of its scattering lengths. We classify each phase according to its reciprocal spinor, using a method developed in a previous work. We show that such a classification can be naturally extended to describe the vortices for a spinor condensate by usin...

Analytical and numerical estimates show that a charged Affleck-Dine condensate will fracture into Q-balls only when the Hubble time is significantly larger than the inverse soft-breaking mass of the field in question. This would generally imply that the decay of the field into light fermions will compete with Q-ball formation. We will show that for typical flat directions the large field value ...

We review the cosmological implications of the flat directions of the Minimally Supersymmetric Standard Model (MSSM). We describe how field condensates are created along the flat directions because of inflationary fluctuations. The post-inflationary dynamical evolution of the field condensate can charge up the condensate with B or L in a process known as Affleck-Dine baryogenesis. Condensate fl...

We present analytical and numerical properties of the coherently rotating AffleckDine condensate formed along MSSM flat directions with the radiative corrections to the mass terms included. We analyse the pressure p of the condensate, which is known to be negative if the potential grows slower than the field squared. We show that ellipticity of the orbit of the rotating field also affects the p...

We investigate the phase structure of the two-flavor dense QCD using the SchwingerDyson equation (SDE) with the improved ladder approximation in the Landau gauge. The SDE for diquark condensate (color superconducting condensate) and that for quarkantiquark condensate (chiral condensate) are solved separately. In the low density region both the SDE’s have nontrivial solutions which correspond to...

We report observation of oscillations in the dynamics of a microcavity polariton condensate formed under pulsed nonresonant excitation. While oscillations in a condensate have always been attributed to Josephson mechanisms due to a chemical potential unbalance, here we show that under some localization conditions of the condensate, they may arise from relaxation oscillations, a pervasive classi...

Recently, effects of Feshbach resonances in atom-atom interactions were observed by varying the external magnetic field of an atomic Bose-Einstein condensate (BEC). We point out that the quasi-bound molecules created in the intermediate state of the resonance can form a second, molecular condensate. The many-body state of the system is then a hybrid atomic/molecular condensate with inter-conden...

The quark condensate which enters the Gell-Mann-Oakes-Renner (GMOR) relation, is investigated in the framework of one-gluon-exchange models. The usual definition of the quark condensate via the trace of the quark propagator produces a logarithmic divergent condensate. In the product of current mass and condensate, this divergence is precisely compensated by the bare current mass. The finite val...
