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 …
The measurement-induced phase transition in strongly disordered spin chains
Yicheng Tang, Pradip Kattel, Arijeet Pal +2
We investigate the dynamics of strongly disordered spin chains in the presence of random local measurements. By studying the transverse-field Ising model with a site-dependent rand…
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…
Two Channel Kondo behavior in the quantum XX chain with a boundary defect
Yicheng Tang, Pradip Kattel, J. H. Pixley +1
We demonstrate that a boundary defect in the single spin- quantum chain exhibits two-channel Kondo physics. Due to the presence of the defect, the edge spin fract…
