Abstract: We learn in elementary statistical mechanics that bosonic systems undergo a phase change even without interparticle interactions, called Bose-Einstein condensation (BEC). Indeed, almost all bosonic systems in the real world such as 4He, cold atoms… read more here.

DOI: 10.1103/physrevb.96.085140
Abstract: We study the quantum criticality of the Lifshitz $\varphi^4$-theory below the upper critical dimension. Two fixed points, one Gaussian and the other non-Gaussian, are identified with zero and finite interaction strengths, respectively. At zero temperature… read more here.

DOI: 10.1103/physrevd.99.084028
Abstract: We analyze the Thermodynamics of massless bosonic systems in D-dimensional anti-de Sitter (adS) spacetime, considering scalar, electromagnetic and gravitational fields. The dynamics of the several fields of interest are described by P\"{o}schl-Teller effective potentials. The… read more here.
