A simple model for magnetic inelastic dark matter (MiDM)
Sudhanwa Patra, Soumya Rao
A simple model for magnetic inelastic dark matter (MiDM), which is a minimal extension of the standard model with right-handed neutrinos (), a singly charged scalar () and…
Scalar Neutrino as Asymmetric Dark Matter: Radiative Neutrino Mass and Leptogenesis
Ernest Ma, Utpal Sarkar
In the Minimal Supersymmetric Standard Model (MSSM), the scalar neutrino has odd R parity, yet it has long been eliminated as a dark-matter candidate because it scatter…
Spectral fluctuation and noise in the energy level statistics of interacting trapped bosons
Kamalika Roy, Barnali Chakrabarti, Anindya Biswas +2
It has been recently shown numerically that the transition from integrability to chaos in quantum systems and the corresponding spectral fluctuations are characterized by $\frac{1}…
Neutrino processes with power law dispersion relations
Subhendra Mohanty, Soumya Rao
We compute various processes involving neutrinos in the initial and/or final state and we assume that neutrinos have energy momentum relation with a general power law $E^2 =p^2+ ξ_…
Extreme events and event size fluctuations in biased random walks on networks
Vimal Kishore, M. S. Santhanam, R. E. Amritkar
Random walk on discrete lattice models is important to understand various types of transport processes. The extreme events, defined as exceedences of the flux of walkers above a pr…
Synchronization of coupled nonidentical dynamical systems
Suman Acharyya, R. E. Amritkar
We analyze the stability of synchronized state for coupled nearly identical dynamical systems on networks by deriving an approximate Master Stability Function (MSF). Using this MSF…
