Spontaneous symmetry breaking in a driven-dissipative system
J. Smits, H. T. C. Stoof, P. van der Straten
Spontaneous symmetry breaking (SSB) is a key concept in physics that for decades has played a crucial role in the description of many physical phenomena in a large number of differ…
Inhomogeneous Fermi mixtures at Unitarity: Bogoliubov-de Gennes vs. Landau-Ginzburg
J. M. Diederix, K. B. Gubbels, H. T. C. Stoof
We present an inhomogeneous theory for the low-temperature properties of a resonantly interacting Fermi mixture in a trap that goes beyond the local-density approximation. We compa…
Correlation Effects in Ultracold Two-Dimensional Bose Gases
Lih-King Lim, C. Morais Smith, H. T. C. Stoof
We study various properties of an ultracold two-dimensional (2D) Bose gas that are beyond a mean-field description. We first derive the effective interaction for such a system as r…
Achieving the Neel state in an optical lattice
Arnaud Koetsier, R. A. Duine, Immanuel Bloch +1
We theoretically study the possibility of reaching the antiferromagnetic phase of the Hubbard model by starting from a normal gas of trapped fermionic atoms and adiabatically rampi…
Renormalization Group Theory for the Imbalanced Fermi Gas
K. B. Gubbels, H. T. C. Stoof
We formulate a wilsonian renormalization group theory for the imbalanced Fermi gas. The theory is able to recover quantitatively well-established results in both the weak-coupling…
Bogoliubov theory of Feshbach molecules in the BEC-BCS crossover
M. W. J. Romans, H. T. C. Stoof
We present the Bogoliubov theory for the Bose-Einstein condensation of Feshbach molecules in a balanced Fermi mixture. Because the Bogoliubov theory includes (Gaussian) fluctuation…
