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…
Attractive Coulomb interactions in a triple quantum dot
Changki Hong, Gwangsu Yoo, Jinhong Park +7
Electron pairing due to a repulsive Coulomb interaction in a triple quantum dot (TQD) is experimentally studied. It is found that electron pairing in two dots of a TQD is mediated…
Anisotropic charge Kondo effect in a triple quantum dot
Gwangsu Yoo, Jinhong Park, S. -S. B. Lee +1
We predict that an anisotropic charge Kondo effect appears in a triple quantum dot, when the system has two-fold degenerate ground states of (1,1,0) and (0,0,1) charge configuratio…
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…
Quantum noise and mode nonorthogonality in nonhermitian PT-symmetric optical resonators
Gwangsu Yoo, H. -S. Sim, Henning Schomerus
PT-symmetric optical resonators combine absorbing regions with active, amplifying regions. The latter are the source of radiation generated via spontaneous and stimulated emission,…
