strange quark matter in a color flavor locked ( cfl ) state can be the true ground state of hadronic matter for a much wider range of the parameters of the model ( the gap of the qcd cooper pairs $ \ delta $, the strange quark mass $ m _ s $ and the bag constant $ b $ ) than the state without any pairing. we review the... | arxiv:astro-ph/0211638 |
we study the spectral rigidity of the non - hermitian analog of the anderson model suggested by tzortzakakis, makris and economou ( tme ). this is a $ l \ times l \ times l $ tightly bound cubic lattice, where both real and imaginary parts of on - site energies are independent random variables uniformly distributed bet... | arxiv:2007.02380 |
the icecube collaboration has built an in - ice neutrino telescope and a surface detector array, icetop, at the south pole. over 5000 digital optical modules have been deployed in a cubic kilometer of ice between 1450 and 2450 m below the surface. the novel observatory provides a new window to explore the universe. the... | arxiv:1110.1600 |
