Density profiles of Ar adsorbed in slits of CO2: spontaneous symmetry breaking revisited.
نویسندگان
چکیده
A recently reported symmetry breaking of density profiles of fluid argon confined by two parallel solid walls of carbon dioxide is studied. The calculations are performed in the framework of a nonlocal density functional theory. It is shown that the existence of such asymmetrical solutions is restricted to a special choice for the adsorption potential, where the attraction of the solid-fluid interaction is reduced by the introduction of a hard-wall repulsion. The behavior as a function of the slit's width is also discussed. All the results are placed in the context of the current knowledge on this matter.

No-go theorem on spontaneous parity breaking revisited
An essential assumption in the Vafa and Witten’s theorem on P and CT realization in vector-like theories concerns the existence of a free energy density in Euclidean space in the presence of any external hermitian symmetry breaking source. We show how this requires the previous assumption that the symmetry is realized in the vacuum. Even if Vafa and Witten’s conjecture is plausible, actually a ...

The importance of the spectral density of the Dirac operator in studying spontaneous chiral symmetry breaking and anomalous U(1)A symmetry breaking are reviewed. It is shown that both types of symmetry breaking can be traced to effects of modes near zero virtuality. Above Tc, where chiral symmetry is restored, it is shown on general grounds that (in the mq → 0 limit), the density of states vani...

Due to a basic ambiguity in the p → 0 limit of the connected propagator, the conventional singlet Higgs boson of spontaneously broken theories is not a purely massive field but has a gap-less branch. This dominates the energy spectrum for p → 0 and gives rise to a long-range force. Its natural interpretation is in terms of density fluctuations of the ‘Higgs condensate’ that cannot be treated as...

The energy density of the universe today may be dominated by the vacuum energy of a slowly rolling scalar field. Making a quantum expansion around such a time dependent solution is found to break fundamental symmetries of quantum field theory. We call this mechanism cosmological symmetry breaking and argue that it is different from the standard phenomenon of spontaneous symmetry breaking. We il...
متن کاملPseudogap and time reversal breaking in a holographic superconductor
Classical SU(2) Yang-Mills theory in 3+1 dimensional anti-de Sitter space is known to provide a holographic dual to a 2+1 system that undergoes a superconducting phase transition. We study the electrical conductivity and spectral density of an isotropic superconducting phase. We show that the theory exhibits a pseudogap at low temperatures and a nonzero Hall conductivity. The Hall conductivity ...
