The "Moiré Capacitor Effect" and Stabilization of Fractional Chern Insulators in Rhombohedral Graphene Superlattices
Nicolas Regnault, Heqiu Li, Yves H. Kwan +2
While the necessity of a moiré potential for fractional Chern insulators (FCIs) in rhombohedral graphene-hBN superlattices, first predicted in Ref. 1, is now grounded in experiment…
Breakdown of Monotonic Impurity Entropy Flow in -Symmetric Multichannel Kondo Systems
Pradip Kattel, Abay Zhakenov, Natan Andrei
We study a -symmetric non-Hermitian multichannel Kondo model consisting of a pair of spin- impurities coupled to conduction-electron channels through com…
Monotonic and non-Nonmonotonic Impurity Entropy flows in a -Symmetric Kondo Model
Pradip Kattel, Abay Zhakenov, Natan Andrei
Quantum impurity models provide a paradigmatic setting for studying Kondo screening, boundary criticality, and impurity entropy. While these phenomena are well understood in unitar…
Dissipation driven phase transition in the non-Hermitian Kondo model
Pradip Kattel, Abay Zhakenov, Parameshwar R. Pasnoori +2
Non-Hermitian Hamiltonians capture several aspects of open quantum systems, such as dissipation of energy and non-unitary evolution. An example is an optical lattice where the inel…
Multichannel Kondo Effect in Superconducting Leads
Pradip Kattel, Abay Zhakenov, Natan Andrei
The traditional multichannel Kondo effect takes place when several gapless metallic electronic channels interact with a localized spin- impurity, with the number of channels …
Competing color superconductivity and color Kondo effect in quark matter
Pradip Kattel, Abay Zhakenov, Natan Andrei
The competition between bulk color superconductivity and the localized screening of a heavy quark impurity, analogous to the Kondo effect, leads to a rich spectrum of phenomena in…
