Non-Fermi-liquid Kondo screening under Rabi driving
Seung-Sup B. Lee, Jan von Delft, Moshe Goldstein
We investigate a Rabi-Kondo model describing an optically driven two-channel quantum dot device featuring a non-Fermi-liquid Kondo effect. Optically induced Rabi oscillation betwee…
Detecting Kondo Entanglement by Electron Conductance
Gwangsu Yoo, Seung-Sup B. Lee, H. -S. Sim
Quantum entanglement between an impurity spin and electrons nearby is a key property of the single-channel Kondo effects. We show that the entanglement can be detected by measuring…
Numerical renormalization group method for entanglement negativity at finite temperature
Jeongmin Shim, H. -S. Sim, Seung-Sup B. Lee
We develop a numerical method to compute the negativity, an entanglement measure for mixed states, between the impurity and the bath in quantum impurity systems at finite temperatu…
Nonlocal Entanglement of 1D Thermal States Induced by Fermion Exchange Statistics
YeJe Park, Jeongmin Shim, S. -S. B. Lee +1
When two identical fermions exchange their positions, their wave function gains phase factor . We show that this distance-independent effect can induce nonlocal entanglement in…
Adaptive broadening to improve spectral resolution in the numerical renormalization group
Seung-Sup B. Lee, Andreas Weichselbaum
We propose an adaptive scheme of broadening the discrete spectral data from numerical renormalization group (NRG) calculations to improve the resolution of dynamical properties at…
Negative- Anisotropic Charge Kondo Effect in a Triple Quantum Dot
Gwangsu Yoo, Jinhong Park, S. -S. B. Lee +1
We predict a new type of the negative- Anderson impurity formed in a triple quantum dot. The two dots of the system behave as a negative- impurity preferring zero or double e…
How to directly measure a Kondo cloud's length
Jinhong Park, S. -S. B. Lee, Yuval Oreg +1
We propose a method to directly measure, by electrical means, the Kondo screening cloud formed by an Anderson impurity coupled to semi-infinite quantum wires, on which an electrost…
