Quantum limited measurement of magnetic field gradient with entangled atoms
Quantum limited measurement magnetic field gradient entangled atoms
2016/1/23
We propose a method to detect the amplitude gradient of a microwave field by using a pair of entangled two-component Bose-Einstein condensates. We consider the two spatially separated condensates to b...
Topological Insulator Magnetic Tunnel Junctions: Quantum Hall Effect and Fractional Charge via Folding
Topological Insulator Magnetic Tunnel Junctions Quantum Hall Effect Fractional Charge Folding
2012/2/27
We provide a characterization of tunneling between coupled topological insulators in 2D and 3D under the influence of a ferromagnetic layer. We explore conditions for such systems to exhibit integer q...
