We revisit the interplay between superconductivity and quantum criticality when thermal effects from virtual static bosons are included. These contributions, which arise from an effective theory compactified on the thermal ...

We address the problem of superconductivity for non-Fermi liquids using two commonly adopted, yet apparently distinct, methods: (1) the renormalization group (RG) and (2) Eliashberg theory. The extent to which both methods ...

We study an ultracold and dilute superfluid Bose-Fermi mixture confined in a strictly one-dimensional (1D) atomic waveguide by using a set of coupled nonlinear mean-field equations obtained from the Lieb-Liniger energy ...

The study of strongly correlated systems is a big challenge for theoretical physics. Such analysis gives us a better understanding of important collective phenomena, which are manifest in a variety of applications and in ...

We prove that in Thomas-Fermi-Dirac-von Weizsacker theory, a nucleus of charge Z>0 can bind at most Z+C electrons, where C is a universal constant. This result is obtained through a comparison with Thomas-Fermi theory ...

Non-Fermi liquids in d=2 spatial dimensions can arise from coupling a Fermi surface to a gapless boson. At finite temperature, however, the perturbative quantum field theory description breaks down due to infrared divergences. ...

We study the quantum theory of a Fermi surface coupled to a gapless boson scalar in D = 4 − ε space-time dimensions as a simple model for non-Fermi liquids (NFL) near a quantum phase transition. Our analysis takes into ...
