Estimate decoherence time and length?

AI Thread Summary
The discussion focuses on estimating decoherence time and length for a superconductor-normal-superconductor (SNS) structure using voltage, current, and resistivity values. Participants seek a formula to calculate these parameters, specifically in the context of measurements taken at room and low temperatures. There is a noted difficulty in understanding explanations that rely on Hamiltonian mechanics, which are commonly found in literature. The conversation emphasizes the need for clearer methodologies or alternative approaches to derive the required decoherence metrics. Overall, the thread highlights the complexity of decoherence phenomena in superconducting systems and the challenges in applying theoretical frameworks.

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.
 

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
