Tunnelling of entangled Kondo singlet in two-reservoir nanocontact systems under bias
Jongbae Hong, S. G. Chung
Tunnelling conductances observed for mesoscopic Kondo systems exhibit a zero-bias peak and two coherent side peaks. The former peak is usually understood as a Kondo effect and the…
New method for the quantum ground states in one dimension
S. G. Chung
A simple, general and practically exact method is developed to calculate the ground states of 1D macroscopic quantum systems with translational symmetry. Applied to the Hubbard mod…
Landauer-like formula for dissipative tunneling
S. G. Chung
The Landauer formula for electrical conductance is simple but works remarkably well in mesoscopic systems. We propose a Landauer-like formula for calculating an escape rate out of…
Theory of superconductor-insulator transition in single Josephson junctions
S. G. Chung
A non-band theory is developed to describe the superconductor-insulator (SI) transtition in resistively shunted, single Josephson junctions. The characteristic is formulated…
Spontaneous Symmetry Breaking in the Quantum Sine-Gordon Model
S. G. Chung
The spontaneous symmetry breaking in the quantum sine-Gordon model is studied by a density matrix renormalization group. A phase diagram in the coupling constant - system size plan…
