Resonant relaxation in protoplanetary disks
Resonant relaxation is a novel form of two-body relaxation that arises in nearly Keplerian disks such as protoplanetary disks. Resonant relaxation does not affect the semimajor axes of the particles, but enhances relaxation of particle eccentricities and inclinations. The equilibrium state after resonant relaxation is a Rayleigh distribution, with the mean-square eccentricity and inclination in...
متن کاملResonant relaxation in electroweak baryogenesis
1550-7998=20 We compute the leading, chiral charge-changing relaxation term in the quantum transport equations that govern electroweak baryogenesis using the closed time path formulation of nonequilibrium quantum field theory. We show that the relaxation transport coefficients may be resonantly enhanced under appropriate conditions on electroweak model parameters and that such enhancements can ...
متن کاملRESONANT CROSS-RELAXATION TO Cr4+ IN RUBY
Measurements on the resonant cross-relaxation between the monitored Cr ion and a Jahn-Teller Cr*-ion in ruby crystals are described. Values for g„ and D for Cr"" are deduced and compared to other measurements and calculations. 1. EXPERIMENTAL MEASUREMENTS.The effects of various trace Jahn-Teller (JT) impurities on the spin-lattice relaxation time Ti (Cr-: Al 0 ) 2 3_ have been reported /1-3/. M...
متن کاملSpin relaxation mechanism in graphene: resonant scattering by magnetic impurities.
We propose that the observed small (100 ps) spin relaxation time in graphene is due to resonant scattering by local magnetic moments. At resonances, magnetic moments behave as spin hot spots: the spin-flip scattering rates are as large as the spin-conserving ones, as long as the exchange interaction is greater than the resonance width. Smearing of the resonance peaks by the presence of electron...
متن کاملThe Efficiency of Resonant Relaxation around a Massive Black Hole
Resonant relaxation (RR) is a rapid relaxation process that operates in the nearly-Keplerian potential near a massive black hole (MBH). RR dominates the dynamics of compact remnants that inspiral into a MBH and emit gravitational waves (extreme mass ratio inspiral events, EMRIs). RR can either increase the EMRI rate, or strongly suppress it, depending on its still poorly-determined efficiency. ...
