Spectroscopy of the enigmatic short-period cataclysmic variable IR Com in an extended low state
, 2014 We report the occurrence of a deep low state in the eclipsing short-period cataclysmic variable IR Com, lasting more than two years. Spectroscopy obtained in this state shows the system as a detached white dwarf plus low-mass companion, indicating that ...

Bubbling and Large-Scale Structures in Avalanche Dynamics
, 1999 Using a simple lattice model for granular media, we present a scenario of self-organization that we term self-organized structuring where the steady state has several unusual features: (1) large scale space and/or time inhomogeneities and (2) the ...

Ghost decoupling in 't Hooft spectrum for mesons [PDF]
, 1996 We show that the replacement of the ``instantaneous'' 't Hooft's potential with the causal form suggested by equal time canonical quantization in light-cone gauge, which entails the occurrence of negative probability states, does not change the bound ...
