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 …
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…
Measuring work in quantum many-body systems using a dynamical "work agent"
Cheolhee Han, Nadav Katz, Eran Sela
We consider a generic quantum many-body system initiated at thermal equilibrium and driven by an external parameter, and discuss the prospect for measuring the work done by the var…
Realizing the interacting resonant level model using a quantum dot detector
Zhanyu Ma, Matan Lotem, Yigal Meir +1
The interacting resonant level model (IRLM) is the simplest quantum impurity model to display strongly correlated effects in mesoscopic systems, which triggered its extensive theor…
