Photonic band gap via quantum coherence in vortex lattices of Bose gases
O. E. Mustecaplioglu, M. O. Oktel
We investigate the optical response of an atomic Bose-Einstein condensate with a vortex lattice. We find that it is possible for the vortex lattice to act as a photonic crystal and…
d=3 Anisotropic and d=2 tJ Models: Phase Diagrams, Thermodynamic Properties, and Chemical Potential Shift
Michael Hinczewski, A. Nihat Berker
The anisotropic d=3 tJ model is studied by renormalization-group theory, yielding the evolution of the system as interplane coupling is varied from the isotropic three-dimensional…
Two Superconducting Phases in the d=3 Hubbard Model: Phase Diagram and Specific Heat from Renormalization-Group Calculations
Michael Hinczewski, A. Nihat Berker
The phase diagram of the d=3 Hubbard model is calculated as a function of temperature and electron density n_i, in the full range of densities between 0 and 2 electrons per site, u…
Analytical Solution of a Stochastic Content Based Network Model
Muhittin Mungan, Alkan Kabakcioglu, Duygu Balcan +1
We define and completely solve a content-based directed network whose nodes consist of random words and an adjacency rule involving perfect or approximate matches, for an alphabet…
Newton-Cartan connections with torsion
T. Dereli, S. Kocak, M. Limoncu
We re-formulate the notion of a Newton-Cartan manifold and clarify the compatibility conditions of a connection with torsion with the Newton-Cartan structure.
