Competition between Kondo and Kitaev Physics in Kitaev clusters coupled to a fermionic bath
Tathagata Chowdhury, Achim Rosch, Ralf Bulla
Geometrically frustrated quantum impurities coupled to metallic leads have been shown to exhibit rich behavior with a quantum phase transition separating Kondo screened and local m…
Long-range entanglement near a Kondo-destruction quantum critical point
Christopher Wagner, Tathagata Chowdhury, J. H. Pixley +1
The numerical renormalization group is used to study quantum entanglement in the Kondo impurity model with a pseudogapped density of states (…
Phase boundaries of the pseudogap Anderson and Kondo models
Mengxing Cheng, Tathagata Chowdhury, Aaron Mohammed +1
We use the poor man's scaling approach to study the phase boundaries of a pair of quantum impurity models featuring a power-law density of states that gives rise…
Entanglement Entropy Near Kondo-Destruction Quantum Critical Points
J. H. Pixley, Tathagata Chowdhury, M. T. Miecnikowski +3
We study the impurity entanglement entropy in quantum impurity models that feature a Kondo-destruction quantum critical point (QCP) arising from a pseudogap in the conduction…
Critical charge fluctuations in a pseudogap Anderson model
Tathagata Chowdhury, Kevin Ingersent
The Anderson impurity model with a density of states containing a power-law pseudogap centered on the Fermi energy () feat…
Quantum criticality in the two-channel pseudogap Anderson model: A test of the non-crossing approximation
Farzaneh Zamani, Tathagata Chowdhury, Pedro Ribeiro +2
We investigate the dynamical properties of the two-channel Anderson model using the noncrossing approximation (NCA) supplemented by numerical renormalization-group calculations. We…
