Summary of Doctoral Thesis in Physics:: Enhancement of cross-Kerr nonlinearity based on electromanetically induced transparency

Research purpose: to build an analytical model representing the cross Kerr nonlinear coefficient of a four-energy quantum system in the inverse Y configuration in the presence of the Doppler effect. Apply the analytical results to the case of 87Rb at room temperature. Studying the ability to control and enhance the cross Kerr nonlinearity according to the parameters of the associated laser field and the temperature of the environment.

Báo cáo khoa học: Speciﬁc Ca2+-binding motif in the LH1 complex from photosynthetic bacterium Thermochromatium tepidum as revealed by optical spectroscopy and structural modeling

Native and Ca 2+ -depleted light-harvesting–reaction center core complexes (LH1–RC) from the photosynthetic bacterium Thermochromatium(Tch.) tepidum exhibit maximal LH1–Qy absorption at 915 and 889 nm, respec-tively. To understand the structural origins of the spectral variation, we performed spectroscopic and structure modeling investigations.
