Anderson Orthogonality as Measurement Backaction in Coupled Quantum Dots
Will Grant, Sarath Sankar, Elena Cornick +9
Measurement perturbs a quantum system by coupling it to external degrees of freedom, but detector backaction depends on the physical mechanism of measurement itself. In solid-state…
Entropy of Non-Abelian Anyons from Slow Quasiparticle Dynamics in Quantum Hall Interferometers
Eran Sela, Mitali Banerjee
Non-Abelian anyons emerging in fractional quantum Hall states carry a characteristic entropy, , where is the anyon's quantum dimension. This e…
Remote entropy measurement in coupled quantum dots
Owen Sheekey, Tim Child, Elena Cornick +8
Recent experiments have demonstrated that measurements of the entropy change associated with the addition of electrons to semiconductor- and graphene-based quantum dots accurately…
Engineering the localization transition in a Charge-Kondo circuit
Zhanyu Ma, Cheolhee Han, F. Pierre +1
Charge Kondo circuits consist of metallic islands connected by single-mode quantum point contacts (QPCs). The island's charging energy makes these circuits tunable quantum simulato…
Direct signatures of Anderson orthogonality catastrophe in nonequilibrium quantum dots
Sarath Sankar, Joshua Folk, Yigal Meir +1
We propose schemes for unambiguous direct observation of Anderson orthogonality catastrophe (AOC) effects in a quantum dot coupled to a charge detector, allowing to estimate the AO…
Back-action effects in charge detection
Sarath Sankar, Matan Lotem, Joshua Folk +2
Charge detection offers a powerful probe of mesoscopic structures based on quantum dots, but it also invariably results in measurement back-action (MBA). If strong, MBA can be detr…
