The earcup shape accommodates ears of different shapes and sizes, while the headband and pads work together to give it a comfortable fit. The pads need break-in time to soften and provide maximum isolation. As with many Beyerdynamic headphones, they are fully serviceable with spare parts read...
The effect of decoherence on the EIT peak is studied using the theoretical model. A comparative study of the EIT line shape for open and closed V-type system has been done using the theoretical results. In our experiment, we have observed one EIT peak and four saturation peaks in an open...

Consequently, I conceptualize home closed-circuit television as a domestic form of useful television, rooted in the gender and racial politics of American post-war domesticity, and continuing to shape our contemporary relationships with surveillance and home screens. Projecting fantasies of ...
Semiconductor spin qubits have recently seen major advances in coherence time and control fidelities, leading to a single-qubit performance that is on par with other leading qubit platforms. Most of this progress is based on microwave control of single s
