Calculating $\tau$ for Electron in Double Square Well

Click For Summary
SUMMARY

The discussion focuses on calculating the time constant $\tau$ for an electron in a double square well potential characterized by a width of L = 2 Bohr, a depth of \bar{V} = 4, and a separation of R = 3. The relevant equation for $\tau$ is given as $\tau = h/\Delta E$, where $\Delta E$ represents the energy difference between the two lowest energy levels of the potential. Participants seek clarification on how to derive or compute the value of $\Delta E$ for this specific potential configuration.

PREREQUISITES
  • Understanding of quantum mechanics principles, particularly potential wells.
  • Familiarity with atomic units and their application in quantum calculations.
  • Knowledge of energy level calculations in quantum systems.

Homework Statement


Compute [tex]\tau[/tex] for and electron in the double square well potential of width L = 2 Bohr, and depth [tex]\bar{V}[/tex] = 4 and separation R = 3. Use atomic units for your computation.

Homework Equations


In his lecture notes... he gave us [tex]\tau[/tex] = h/[tex]\Delta[/tex]E .

I don't know where that [tex]\Delta[/tex]E comes from.
