Pathways of energy transfer in LHCII revealed by room-temperature 2D electronic spectroscopy by Wells, Kym L., Lambrev, Petar H., Zhang, Zhengyang, Garab, Gyözö, Tan, Howe-Siang

“…Two-dimensional electronic spectroscopy has been used to study energy transfer dynamics in LHCII trimers from the chlorophyll b Qy band to the chlorophyll a Qy band. Observing cross-peak regions corresponding to couplings between different excitonic states reveals partially resolved fine structure at the exciton level that cannot be isolated by pump–probe or linear spectroscopy measurements alone. …”

Investigation of two dimensional floquet topological insulator using microwave network by Hu, Wenchao

“…Due to the existence of loss, the system we used to measure topological edge in-variants is non-Hermitian; furthermore, in the standard theory of the topological pump, we can never observe rigorously non-zero winding in a finite system, since there is always a gap in the projected band structure. …”

Frequency synthesizer design for 60 GHz wireless communication by Chen, Weiping

“…In order to reduce the VCO phase noise, switched capacitor array are adopted to design a wideband VCO with low VCO gain (K_VCO). VCO frequency sub-band interval (f_step) is minimized and the overlap is maximized to narrow the possible tunable voltage range for necessary frequency, which helps to alleviate the operating range requirement of the charge pump (CP). …”

Coherent energy scale revealed by ultrafast dynamics of UX3 (X = Al, Sn, Ga) single crystals by Nair, Saritha K., Zhu, J. X., Sarrao, J. L., Taylor, Antoinette J., Chia, Elbert E. M.

“…The temperature dependence of relaxation dynamics of UX3 (X = Al, Ga, Sn) compounds is studied using the time-resolved pump-probe technique in reflectance geometry. For UGa3, our data are consistent with the formation of a spin density wave gap as evidenced from the quasidivergence of the relaxation time τ near the Néel temperature TN. …”
