Bose-Einstein condensation of particle-hole pairs in ultracold fermionic atoms trapped within optical lattices.
We investigate the Bose-Einstein condensation (BEC, superfluidity) of particle-hole pairs in ultracold fermionic atoms with repulsive interactions and arbitrary polarization, which are trapped within optical lattices. In the strongly repulsive limit, the dynamics of particle-hole pairs can be described by a hard-core Bose-Hubbard model. The insulator-superfluid and charge-density-wave- (CDW) su...
متن کاملSome thoughts on critical and tricritical points and deconfinement
We start with a discussion of a phase diagram and three special collision energies: (i) the first touching of the mixed phase; (ii) the softest point; (iii) the critical point. We then proceed to more details about the role a massless critical mode should play in the particle interaction and the elliptic flow. We then enter a discussion of whether high density QGP is or is not strongly coupled,...
متن کاملTopological charge pumping in a one-dimensional optical lattice.
A topological charge pump transfers charge in a quantized fashion. The quantization is stable against the detailed form of the pumping protocols and external noises and shares the same topological origin as the quantum Hall effect. We propose an experimental setup to realize topological charge pumping of cold fermionic atoms in a one-dimensional optical lattice. The quantization of the pumped c...
متن کاملResonant dynamics in boson-fermion mixtures
The time evolution of a dilute atomic boson-fermion mixture is studied at zero temperature, when the external magnetic field is brought close to a interspecies Feshbach resonance. On short time scales we find that before a collapse or phase separation of the mixture can occur, oscillations between fermionic atoms and heteronuclear molecules dominate the dynamics. Applying the model presented he...
متن کاملFrustrated SU(4) as the Preonic Precursor of the Standard Model
We give a model for composite quarks and leptons based on the semisimple gauge group SU(4), with the preons in the 10 representation. Hypercolor singlets are forbidden in the fermionic sector of this theory; we propose that SU(4) symmetry spontaneously breaks to SU(3)× U(1), with the binding of triality nonzero preons and gluons into composites, and with the formation of a color singlet condens...
