The Role of Relativistic Many-Body Theory in Probing the Standard Model of Particle Physics
Abstract
Relativistic many-body theory has been successfully applied to a number of fundamental problems inphysics. The latest example of this being the application of this theory to the search of the electric dipole moment (EDM) of the electron.My talk will touch upon the connection between the EDM of the electron and the standard model of particle physics and also CP violation. However, its major emphasis will be on the development of aunique relativistic many-body theory and its crucial role in obtaining a new limit for the electron EDM.The implications of this limit will be discussed

Explaining the long coherence effects in photosynthetic exciton energy transfer as observed by 2D photon echo spectroscopy: TCPS model
Explaining the long coherence effects in photosynthetic exciton energy transfer as observed by 2D photon echo spectroscopy: TCPS model
Abstract
We propose a simple stochastic model which successfully explain the longcoherence effects observed in photosynthetic EET by 2D photon echoexperiments of G. S. Engel et. al. (Nature, {f 446} 782, (2007)). OurTwo-Component Phonon Spectrum (TCPS) model is based upon the division ofphonon degrees of freedom into systematic component (treated through Polarontransformation) and the stochastic component (treated through dynamicaldisorder). This model successfully explain the observed long coherence upto$ sim 600 fsec$ in EET experiments and it uses the information of homogeneous broadening from 2-D photon echo spectrum.
