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…
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…
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…
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…
Chiral numerical renormalization group
Matan Lotem, Eran Sela, Moshe Goldstein
The interplay between the Kondo screening of quantum impurities (by the electronic channels to which they couple) and the interimpurity RKKY interactions (mediated by the same chan…
Manipulating Non-Abelian Anyons in a Chiral Multichannel Kondo Model
Matan Lotem, Eran Sela, Moshe Goldstein
Non-Abelian anyons are fractional excitations of gapped topological models believed to describe certain topological superconductors or quantum Hall states. Here, we provide the fir…
Link between superconductivity and a Lifshitz transition in intercalated BiSe
A. Almoalem, I. Silber, S. Sandik +12
Topological superconductivity is an exotic phase of matter in which the fully gapped superconducting bulk hosts gapless Majorana surface states protected by topology. Intercalation…
Renormalized Lindblad Driving: A Numerically-Exact Nonequilibrium Quantum Impurity Solver
Matan Lotem, Andreas Weichselbaum, Jan von Delft +1
The accurate characterization of nonequilibrium strongly-correlated quantum systems has been a longstanding challenge in many-body physics. Notable among them are quantum impurity…
Charting the Parameter Space of the Global 21-cm Signal
Aviad Cohen, Anastasia Fialkov, Rennan Barkana +1
The early star-forming Universe is still poorly constrained, with the properties of high-redshift stars, the first heating sources, and reionization highly uncertain. This leaves o…
