Multiphoton excitations and nonlinear optical properties of exciton states in GaAs/AlxGa1-xAs coupled quantum well structure have been theoretically investigate
We consider a passive and active hybrid interferometer for phase estimation, which can reach the sub-shot-noise limit in phase sensitivity with only the cheapes
In this work,we designed the elliptical thermal cloak based on the transformation thermotics.The local entropy generation rate distribution and entransy dissipa
The applications of magnetrons are greatly limited because of the poor output spectrum of the free-running magnetron.Currently,one of the best ways to solve thi
