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 …
Thermodynamics in a split Hilbert space: Quantum impurity at the edge of the Heisenberg chain
Abay Zhakenov, Pradip Kattel, Natan Andrei
We study the isotropic spin- Heisenberg chain with a single edge-coupled impurity of arbitrary exchange strength . The model exhibits four impurity phases. For anti…
Thermodynamics in a split Hilbert space: Quantum impurity at the edge of a one-dimensional superconductor
Pradip Kattel, Abay Zhakenov, Natan Andrei
We present a thermodynamic description of a single magnetic impurity at the edge of a superconducting wire. The impurity exhibits four phases $\unicode{x2014}$ Kondo, Yu-Shiba-Rusi…
What is the topological dual of the XXZ spin Chain?
Yicheng Tang, Pradip Kattel, Natan Andrei
We construct a dual symmetry-protected topological (SPT) Hamiltonian for the symmetric anisotropic spin- Heisenberg chain-a model that has traditionally been us…
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…
Complete Boundary Phase Diagram of the Spin- XXZ Chain with Boundary Fields in the Anti-Ferromagnetic Gapped Regime
Parameshwar R. Pasnoori, Yicheng Tang, Junhyun Lee +3
We consider the spin XXZ chain with diagonal boundary fields and solve it exactly using Bethe ansatz in the gapped anti-ferromagnetic regime and obtain the complete p…
