Dependence of the Macroscopic Quantum Tunneling Rate on Josephson Junction Area
Macroscopic Quantum Josephson Junction Area
2010/11/24
We have carried out systematic Macroscopic Quantum Tunneling (MQT) experiments on Nb/Al-
AlOx/Nb Josephson junctions (JJs) of different areas. Employing on-chip lumped element inductors,we have decou...
Macroscopic quantum tunneling in multigap superconducting Josephson junctions: Escape rate enhancement via quantum fluctuations of Josephson-Leggett mode
Macroscopic quantum superconducting Josephson Escape rate enhancement Josephson-Leggett mode
2010/11/5
We theoretically study the macroscopic quantum tunneling (MQT) in a hetero Josephson junction formed by a conventional single-gap superconductor and a multi-gap one such as ${MgB}_{2}$ and iron-based...
Instantonic Methods for Quantum Tunneling in Finite Size
Path Integral Methods Finite Size Systems Instantons
2010/7/8
The instantonic approach for a f4 model potential is reexamined in the asymptotic limit. The path integral of the system is derived in semiclassical approximation expanding the action around the class...
Theory of two-dimensional macroscopic quantum tunneling in YBa$_2$ Cu$_3$ O$_{7-\delta}$ Josephson junctions coupled to an LC circuit
two-dimensional macroscopic quantum tunneling LC circuit
2010/4/13
We investigate classical thermal activation (TA) and macroscopic quantum tunneling (MQT) for a YBa$_2$Cu$_3$O$_{7-\delta}$ (YBCO) Josephson junction coupled to an LC circuit theoretically. Due to the ...

Fluctuations, Classical Activation, Quantum Tunneling, and Phase Transitions
Classical Activation Quantum Tunneling Phase Transitions
2010/10/13
We study two broad classes of physically dissimilar problems, each corresponding to stochastically driven escape from a potential well. The first class, often used to model noise-induced order paramet...
Quantum tunneling dynamics using hydrodynamic trajectories
Quantum tunneling dynamics hydrodynamic trajectories
2010/10/18
In this paper we compute quantum trajectories arising from Bohm’s causal description of quantum mechanics. Our computational methodology is based upon a finite-element moving least-squares method (MWL...
