Detectability of Gravitational Waves from Phase Transitions
Tina Kahniashvili, Arthur Kosowsky, Grigol Gogoberidze +1
Gravitational waves potentially represent our only direct probe of the universe when it was less than one second old. In particular, first-order phase transitions in the early univ…
CMB Temperature Anisotropy from Broken Spatial Isotropy due to an Homogeneous Cosmological Magnetic Field
Tina Kahniashvili, George Lavrelashvili, Bharat Ratra
We derive the cosmic microwave background temperature anisotropy two-point correlation function (including off-diagonal correlations) from broken spatial isotropy due to an arbitra…
Discrimination of nuclear recoils from alpha particles with superheated liquids
F. Aubin, M. Auger, E. Behnke +26
The PICASSO collaboration observed for the first time a significant difference between the acoustic signals induced by neutrons and alpha particles in a detector based on superheat…
Quantum Criticality in Dimerized Spin Ladders
Gennady Y. Chitov, Brandon W. Ramakko, Mohamed Azzouz
We analyze a possibility of quantum criticality (gaplessness) in dimerized antiferromagnetic two- and three-leg spin-1/2 ladders. Contrary to earlier studies of these models, we ex…
The Spin-SAF transition in NaV2O5 induced by spin-pseudospin coupling
Claudius Gros, Gennady Y. Chitov
We present microscopic estimates for the spin-spin and spin-speudospin interactions of the quarter-filled ladder compound NaV2O5, obtained by exactly diagonalizing appropriate clus…
