Multibath Influence Matrices: Universal Scaling from Real-Time Dynamics
Matan Lotem, Michael Sonner, Valentin Link +2
Diverging timescales are the hallmark of critical dynamics and the bottleneck to their classical and quantum simulation. To tame this, we compress a spacetime tensor network: tempo…
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…
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…
Relevance of Anisotropy in the Kondo Effect: Lessons From the Symplectic Case
Matan Lotem, Sarath Sankar, Tianhao Ren +5
A Kondo model with symplectic symmetry was recently put forward as the effective low-energy theory of a superconducting-island device coupled to multiple leads. This model, which p…
