Electric dipole moment

In 2008 Nobel Prize in physics was awarded to Yoichiro Nambu "for the discovery of the mechanism of spontaneous broken symmetry in subatomic physics", and to Makoto Kobayashi and Toshihide Maskawa "for the discovery of the origin of the broken symmetry which predicts the existence of at least three families of quarks in nature". The study of nature's broken discrete symmetries (charge conjugation C, parity P, and time reversal T), however, is far from complete. CP-violation is described within the Standard Model by the complex phase in the Cabibbo-Kobayashi-Maskawa quark mixing matrix. It is also well known that this mechanism of CP-violation is not strong enough to explain the observed matter-antimatter asymmetry of the universe. In addition, almost every conceived extension of the Standard Model includes new scalar fields that allow new complex phases, and therefore new sources of CP-violation. We study CP-violation by searching for permanent electric dipole moment (EDM) of the electron in solid ferroelectric ceramics.

Casimir effect

The study of Casimir effect tests our fundamental understanding of quantum field theory, electrodynamics, and statistical physics. Zero-point quantum fluctuations in vacuum separating two macroscopic or microscopic bodies give rise to a force between these bodies. Interest in Casimir effect has recently been on the rise, owing partly due to possibilities of controlling and counteracting attractive Casimir forces, for alleviating friction and stiction in MEMS (micro-electromechanical systems) and NEMS (nano-electromechanical systems).
