Chapter 2
1.) In your own words, describe what the "Standard Model" of physics is using 2 to 5 paragraphs. Your paragraphs should include the concepts of the 4 fundamental forces of physics, QED, and QCD at a minimum. Any sentences in which a string of 5 or more words match a sentence that is found on the internet will be evidence of cheating.
2.) Solve the Schrodinger equation for the following potential:
V_0 > 0 and E>0. Assume particles are incident from
, don't try to normalize but do express the wave function in terms of one coefficient.3.) Given the following barrier potential
show that the transmission coefficient is
- T = \frac{1}{1+ \frac{v_o^2 \sinh^2(k_2a)}{4E(V_o-E)}}
when
Assume particles are incident fromand .
