Joint Sparsity Recovery for Spectral Compressed Sensing [PDF]

, 2014
Compressed Sensing (CS) is an effective approach to reduce the required number of samples for reconstructing a sparse signal in an a priori basis, but may suffer severely from the issue of basis mismatch.

Universality of the EMC Effect

, 2005
Using effective field theory, we investigate nuclear modification of nucleon parton distributions (for example, the EMC effect). We show that the universality of the shape distortion in nuclear parton distributions (the factorisation of the Bjorken x and

Cavity-Assisted Dynamical Spin-Orbit Coupling in Cold Atoms [PDF]

, 2014
We consider ultracold atoms subjected to a cavity-assisted two-photon Raman transition. The Raman coupling gives rise to effective spin-orbit interaction which couples atom's center-of-mass motion to its pseudospin degrees of freedom.

Effective Quantum Dynamics of Interacting Systems with Inhomogeneous Coupling [PDF]

, 2006
We study the quantum dynamics of a single mode/particle interacting inhomogeneously with a large number of particles and introduce an effective approach to find the accessible Hilbert space where the dynamics takes place. Two relevant examples are given:

Determination of the effective atomic number: A theoretical justification

EPL (Europhysics Letters), 2018
In this paper, we have tried to seek a theoretical justification for the effective atomic number for Compton scattering studies by computing it from free atom Hartree-Fock wave function based Compton profiles compiled by Biggs et al. Typical experimental examples have been provided which show a good agreement with that of theory justifying the validity
