Strong Spectral Gaps for Compact Quotients of Products of $\PSL(2,\bbR)$ math.NT The existence of a strong spectral gap for quotients $\Gamma\bs G$ of noncompact connected semisimple Lie groups is crucial in many applications. For congruence lattices there are uniform and very good bounds for the spectral gap comin...

Distinguishing seesaw models at LHC with multi-lepton signals hep-ph We investigate the LHC discovery potential for electroweak scale heavy neutrino singlets (seesaw I), scalar triplets (seesaw II) and fermion triplets (seesaw III). For seesaw I we consider a heavy Majorana neutrino coupling to the electron or muon...

Conditions for the spin-spiral state in itinerant magnets cond-mat.mtrl-sci The spin-spiral (SS) type of magnetization is studied with the Hubbard model. Consideration of noncollinearity of the magnetic moments results in a phase diagram which consists of regions of the SS and paramagnetic states depending on the n...
