New General decay rates of solutions for two viscoelastic wave equations with Infinite Memory
Mathematical Modelling and Analysis, 2020 We consider in this paper the problem of asymptotic behavior of solutions for two viscoelastic wave equations with infinite memory. We show that the stability of the system holds for a much larger class of kernels and get better decay rate than the ...

A General Decay and Optimal Decay Result in a Heat System with a Viscoelastic Term [PDF]
Acta Mathematica Scientia, 2019 We consider a quasilinear heat system in the presence of an integral term and establish a general and optimal decay result from which improves and generalizes several stability results in the literature.

Majorana neutrino decay in an Effective Approach [PDF]
, 2015 The search strategy or the finding of new effects for heavy neutrinos often relies on their different decay channels to detectable particles. In particular in this work we study the decay of a Majorana neutrino with interactions obtained from an ...

Radiative decays of dynamically generated charmed baryons [PDF]
Physical Review D, 2011 In this work we study the radiative decay of dynamically generated $J^P=\oh^-$ charm baryons into the ground state $J^P=\oh^+$ baryons. Since different theoretical interpretations of these baryonic resonances, and in particular of the $ _c(2595)$, give different predictions, a precise experimental measurement of these decays would be an important step

Correlations, spectral gap, and entanglement in harmonic quantum systems on generic lattices
, 2006 We investigate the relationship between the gap between the energy of the ground state and the first excited state and the decay of correlation functions in harmonic lattice systems.

Separation of Transitions with Two Quantum Jumps from Cascades [PDF]
, 2010 We consider the general scenario of an excited level |i> of a quantum system that can decay via two channels: (i) via a single-quantum jump to an intermediate, resonant level |bar m>, followed by a second single-quantum jump to a final level |f>, and (ii)

Stability of Excited Dressed States with Spin-Orbit Coupling
, 2013 We study the decay behaviors of ultracold atoms in metastable states with spin-orbit coupling (SOC), and demonstrate that there are two SOC-induced decay mechanisms. One arises from the trapping potential and the other is due to interatomic collision. We

Fermionic decay of a massive scalar in the early Universe
, 2019 We derive a curved space generalization of a scalar to fermion decay rate with a Yukawa coupling in expanding Friedmann-Robertson-Walker universes. This is done using the full theory of quantum fields in curved spacetime and the added-up transition ...

Time decay of scaling invariant Schroedinger equations on the plane [PDF]
, 2014 We prove the sharp L^1-L^{\infty} time-decay estimate for the 2D-Schroedinger equation with a general family of scaling critical electromagnetic potentials.Comment: 26 ...
