Quantum Battery Based on Superabsorption
نویسندگان
چکیده
A quantum battery is a device where an energy charged by using effect. Here, we propose with charger system composed of N qubits utilizing collective effect called superabsorption. Importantly, the coupling strength between and can be enhanced due to entanglement. While charging time scales as Θ(N−1/2) applying conventional scheme, achieve Θ(N−1) in our scheme. Our results open path ultra-fast battery.

Superabsorption of light via quantum engineering
Almost 60 years ago Dicke introduced the term superradiance to describe a signature quantum effect: N atoms can collectively emit light at a rate proportional to N(2). Structures that superradiate must also have enhanced absorption, but the former always dominates in natural systems. Here we show that this restriction can be overcome by combining several well-established quantum control techniq...
متن کاملBattery Operation Time Enhancement Based On Alternating Battery Cell Discharge
This paper proposes an alternating discharge method of multiple battery cells to extend battery operation time. In the proposed method, two battery cells are periodically connected in turn to a mobile device and only one cell supply power while the other rests. Battery operation time of the connecting cell decreases due to rate-capacity effect, while that of the resting cell increases due to re...
متن کاملmortality forecasting based on lee-carter model
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...

متن کاملSuperabsorption of light by multilayer nanowires.
We suggest a new strategy for tailoring and enhancing the absorption of light by multilayered nanowires. We use the multipole expansion method and experimental data for dielectric and plasmonic materials and demonstrate that the absorption for one of the polarizations can be substantially enhanced due to an overlap of different resonant modes in nanowires. We show that our approach can be emplo...
