parafermion in the double charge-Kondo model
D. B. Karki, Edouard Boulat, Winston Pouse +3
Quantum impurity models with frustrated Kondo interactions can support quantum critical points with fractionalized excitations. Recent experiments [arXiv:2108.12691] on a circuit c…
Fractional entropy of multichannel Kondo systems from conductance-charge relations
Cheolhee Han, Zubair Iftikhar, Yaakov Kleeorin +5
Fractional entropy is a signature of nonlocal degrees of freedom, such as Majorana zero modes or more exotic non-Abelian anyons. Although direct experimental measurements remain ch…
Quantum simulation of an exotic quantum critical point in a two-site charge Kondo circuit
Winston Pouse, Lucas Peeters, Connie L. Hsueh +5
Tuning a material to the cusp between two distinct ground states can produce exotic physical properties, unlike those in either of the neighboring phases. The prospect of designing…
Kondo blockade due to quantum interference in single-molecule junctions
Andrew K. Mitchell, Kim G. L. Pedersen, Per Hedegaard +1
Molecular electronics offers unique scientific and technological possibilities, resulting from both the nanometre scale of the devices and their reproducible chemical complexity. T…
Signatures of Weyl semimetals in quasiparticle interference
Andrew K. Mitchell, Lars Fritz
Impurities act as in situ probes of nontrivial electronic structure, causing real-space modulations in the density of states detected by scanning tunneling spectroscopy on the samp…
Screening mechanisms in magnetic nanostructures
Andrej Schwabe, Mirek Hänsel, Michael Potthoff +1
A theoretical concept is presented for the screening of several magnetic moments locally exchange coupled to conduction electrons in a metallic nanostructure. We consider a quantum…
