    Dhar, A; Maji, M; Mishra, T; Pai, R. V; Mukerjee, S; Paramekanti, A (American Physical Society, 2012-04)
    Motivated by experiments on Josephson junction arrays, and cold atoms in an optical lattice in a synthetic magnetic field, we study the “fully frustrated” Bose-Hubbard model with half a magnetic flux quantum per plaquette. ...

    Recently Coleman and Glashow [Phys. Lett. B 405 (1997) 249; Harvard University Theoretical Physics Preprint 98/AO76 (pvt. comm)] have developed a model which allows the introduction of a small violation of Lorentz invariance. ...

    Tripathi, B. M; Pande, M. C (Astronomical Society of India, 1981-12)
    An attempt has been made to show that the profile of the Brackett-gamma line can distinguish between different facula models. It is suggested that low noise high resolution scans of Brackett lines can help improve the ...
