Time crystals: can diamagnetic currents drive a charge density wave into rotation?
Philippe Nozières
It has been argued recently that an inhomogeneous system could rotate spontaneously in its ground state - hence a 'time crystal' which is periodic in time. In this note we present…
Superconductivity with hard-core repulsion: BCS-Bose crossover and s-/d-wave competition
F. Pistolesi, Ph. Nozieres
We consider fermions on a 2D lattice interacting repulsively on the same site and attractively on the nearest neighbor sites. The model is relevant, for instance, to study the comp…
Transition from BCS pairing to Bose-Einstein condensation in low-density asymmetric nuclear matter
U. Lombardo, P. Nozieres, P. Schuck +2
We study the isospin-singlet neutron-proton pairing in bulk nuclear matter as a function of density and isospin asymmetry within the BCS formalism. In the high-density, weak-coupli…
Four-particle condensate in strongly coupled fermion systems
G. Roepke, A. Schnell, P. Schuck +1
Four-particle correlations in fermion systems at finite temperatures are investigated with special attention to the formation of a condensate. Instead of the instability of the nor…
Instability of the marginal commutative model of tunneling centers interacting with metallic environment: Role of the electron-hole symmetry breaking
A. Zawadowski, G. Zarand, P. Nozieres +2
The role of the electron-hole symmetry breaking is investigated for a symmetrical commutative two-level system in a metal using the multiplicative renormalization group in a straig…
