Estimate decoherence time and length?

Click For Summary
SUMMARY

The discussion focuses on estimating decoherence time and decoherence length for a superconductor-normal-superconductor (SNS) structure using voltage, current, and resistivity values. The user seeks to calculate these parameters along with the diffusion coefficient, particularly in the context of measurements taken at room and low temperatures. The conversation highlights the need for a clear formula, as existing literature often employs Hamiltonian methods that are difficult to interpret.

PREREQUISITES
  • Understanding of decoherence in quantum systems
  • Familiarity with superconductor-normal-superconductor (SNS) structures
  • Knowledge of electrical measurements (voltage, current, resistivity)
  • Basic principles of quantum mechanics and Hamiltonian mechanics
NEXT STEPS
  • Research the formula for calculating decoherence time and length in SNS structures
  • Study the role of diffusion coefficients in quantum systems
  • Explore Hamiltonian methods in quantum mechanics for better comprehension
  • Investigate experimental techniques for measuring voltage and current in superconductors
USEFUL FOR

Researchers in quantum physics, materials scientists, and engineers working with superconducting materials and quantum coherence phenomena.

what is the formula for estimate decoherence time and decoherence length from voltage, current and resistivity value ?
 
Physics news on Phys.org
Decoherence of what?
And in which type of system?
 
My sample has SNS(superconductor-normal-superconductor) structure and I did, room temperature and low temperature measurement for it.
now I want to estimate decoherence length , decoherence time and diffusion coefficient for this sample.
In the most articles the explanation way is with Hamiltonian who I couldn't follow it exactly.
