Q: What is the quantum mechanical expression for resistivity of Plasma?
 
Physics news on Phys.org
Are you talking about the inverse of Hall conductivity?

I know that the Hall parameter β beta in a plasma is the ratio between the electron gyrofrequency Ωe and the electron-heavy particle collision frequency ν:

β beta = Omega_e / nu = e * B / (m_e nu)

where

e is the electron charge (1.6 × 10-19 coulomb)
B is the magnetic field (in teslas)
m_e is the electron mass (0.9 × 10-30 kg).

Does that help?
 
I want to know the expression of Ohm's law at the level of quantum mechanics, ie. in expression of resistivity of Plasma there must be a h (Plank constant).
What will be the expression of row ( resistivity) of Plasma in terms of h ( Plank constant)?
 
Not an expert in QM. AFAIK, Schrödinger's equation is quite different from the classical wave equation. The former is an equation for the dynamics of the state of a (quantum?) system, the latter is an equation for the dynamics of a (classical) degree of freedom. As a matter of fact, Schrödinger's equation is first order in time derivatives, while the classical wave equation is second order. But, AFAIK, Schrödinger's equation is a wave equation; only its interpretation makes it non-classical...

Is it possible, and fruitful, to use certain conceptual and technical tools from effective field theory (coarse-graining/integrating-out, power-counting, matching, RG) to think about the relationship between the fundamental (quantum) and the emergent (classical), both to account for the quasi-autonomy of the classical level and to quantify residual quantum corrections? By “emergent,” I mean the following: after integrating out fast/irrelevant quantum degrees of freedom (high-energy modes...
