Triumphs and tribulations of ?CDM


In this talk, first we will show that how the standard model of cosmology known as ?CDM can describe almost all cosmological observations from cosmic microwave background radiation to the late time large scale structure observations. Then we discuss the observations that introduce tensions with the standard model such as missing baryon problem, missing satellite problem, the H_0 tension and sigma-8 problem. Accordingly, we propose some proposal for solving or relaxing these tensions. In this direction, we assert that the baryon-dark matter relation known as the bias parameter is an important corner-stone in cosmological studies to address the ...

Super-resolved 3D imaging


Super-resolved 3D imaging

Most of biology specimens, in particular living cells, are transparent and differ only
slightly from their surroundings in terms of the amplitude of the light wave. 3D
imaging methods, including digital holographic microscopy (DHM) and integral
imaging (II), provide noninvasive quantitative phase contrast imaging and are suitable techniques for such samples. As for other imaging techniques the enhancing of the resolution of these methods are of high interest. In this talk, we report the results of our recent approaches toward improving the resolution in 3D imaging: Microsphereas ...

Physics and Technologies of Normal Conducting High Gradient Cavities


Reaching higher energy in particle linear accelerators needs the higher axial electric field inside the RF cavities. CLIC's goal to reach TeV energy range push him to reach higher gradient field in the level of 100MV/m. Enormous studies and experiments was done to discover the special behavior of cavities in this range and to reduce their breakdown rate. Nowadays, these studies find his own way in other applications like compact free electron lasers, inverse Compton scattering x-ray source, Hadron-therapy and so in. IPM as one of CLIC's members proposed and wish to extend these studies to S-Band cavities with new fabrication and assembly tech ...

On the Local Langlands Program


I will talk about the Langlands Correspondence philosophy and more specifically about the Local Langlands Program. If time permits, I will also talk about the main ideas of the proof of the Local Langlands Correspondence in the GL_n case, and say few words about my ongoing research in this area. ...
