Classifying coherent peaks in nanoelectronic devices by the presence or absence of spin exchange
Jongbae Hong
Coherent peaks appearing in the differential conductance of quantum-dot single-electron transistors (QDSETs) and quantum point contact (QPC) devices are classified into two categor…

Classification of coherent peaks in two-terminal quantum devices into normal and anomalous Kondo peaks
Jongbae Hong
Coherent peaks arising in the differential conductance of quantum dot (QD) and quantum point contact (QPC) devices are classified into two categories, normal and anomalous Kondo pe…

Gate-voltage-driven quantum phase transition at in quantum point contacts
Jongbae Hong
We investigate a quantum phase transition (QPT) in quantum point contacts by analyzing the gate-voltage-dependent quasiparticle energy at the Fermi level at zero temperature. This…
