Dynamical scaling and Planckian dissipation due to heavy-fermion quantum criticality
Andreas Gleis, Seung-Sup B. Lee, Gabriel Kotliar +1
We study dynamical scaling associated with a Kondo-breakdown quantum critical point (KB-QCP) of the periodic Anderson model, treated by two-site cellular dynamical mean-field theor…
Emergent Properties of the Periodic Anderson Model: a High-Resolution, Real-Frequency Study of Heavy-Fermion Quantum Criticality
Andreas Gleis, Seung-Sup B. Lee, Gabriel Kotliar +1
We study paramagnetic quantum criticality in the periodic Anderson model (PAM) using cellular dynamical mean-field theory, with the numerical renormalization group (NRG) as an impu…
Macroscopic Quantum Entanglement of a Kondo Cloud at Finite Temperature
S. -S. B. Lee, Jinhong Park, H. -S. Sim
We propose a variational approach for computing the macroscopic entanglement in a many-body mixed state, based on entanglement witness operators, and compute the entanglement of fo…
Minimax optimization of entanglement witness operator for the quantification of three-qubit mixed-state entanglement
Sungguen Ryu, Seung-Sup B. Lee, H. -S. Sim
We develop a numerical approach for quantifying entanglement in mixed quantum states by convex-roof entanglement measures, based on the optimal entanglement witness operator and th…
Quantifying mixed-state quantum entanglement by optimal entanglement witness
S. -S. B. Lee, H. -S. Sim
We develop an approach of quantifying entanglement in mixed quantum states by the optimal entanglement witness operator. We identify the convex set of mixed states for which a sing…
Interferometric distillation and determination of unknown two-qubit entanglement
S. -S. B. Lee, H. -S. Sim
We propose a scheme for both distilling and quantifying entanglement, applicable to individual copies of an arbitrary unknown two-qubit state. It is realized in a usual two-qubit i…
