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…

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…
