Proposal for a cumulant-based Bell test for mesoscopic junctions

, 2011
The creation and detection of entanglement in solid state electronics is of fundamental importance for quantum information processing. We prove that second-order quantum correlations can be always interpreted classically and propose a general test of ...

Linear Extended State Observer-Based Backstepping Sliding Mode Control For DC-Bus Voltage Regulation Under Constant Power Loads In DC Microgrids

Journal of Applied Science and Engineering
In DC microgrids, Constant Power Load (CPL) is one of the causes to generate negative incremental resistance, which significantly reduces the stability margin and may lead to DC-bus voltage fluctuations.
