A Real-time Instanton Approach to Quantum Activation
Chang-Woo Lee, Paul Brookes, Kee-Su Park +2
Driven-dissipative nonlinear systems exhibit rich critical behavior, related to bifurcation, bistability and switching, which underlie key phenomena in areas ranging from physics,…
Continuous and reversible tuning of the disorder-driven superconductor-insulator transition in bilayer graphene
Gil-Ho Lee, Dongchan Jeong, Kee-Su Park +3
The influence of static disorder on a quantum phase transition (QPT) is a fundamental issue in condensed matter physics. As a prototypical example of a disorder-tuned QPT, the supe…
Topological effects, index theorem and supersymmetry in graphene
Kee-Su Park
We present the electronic properties of massless Dirac fermions characterized by geometry and topology on a graphene sheet in this chapter. Topological effects can be elegantly ill…
Inelastic scattering in a monolayer graphene sheet; a weak-localization study
Dong-Keun Ki, Dongchan Jeong, Jae-Hyun Choi +2
Charge carriers in a graphene sheet, a single layer of graphite, exhibit much distinctive characteristics to those in other two-dimensional electronic systems because of their chir…
Pseudogap Behavior Revealed in Interlayer Tunneling in Overdoped BiSrCaCuO
Myung-Ho Bae, Jae-Hyun Park, Jae-Hyun Choi +2
We report heating-compensated interlayer tunneling spectroscopy (ITS) performed on stacks of overdoped BiSrCaCuO intrinsic junctions, where most of bias-induced…
Decoherence in Josephson vortex quantum bits
Ju H. Kim, Ramesh P. Dhungana, Kee-Su Park
We investigated decoherence of a Josephson vortex quantum bit (qubit) in dissipative and noisy environment. As the Josephson vortex qubit (JVQ) is fabricated by using a long Joseph…
