Field Theory Georgia Tech PHYS-7147 spring 2005 Tue, Thu 12:05-13:25 Howey S107 Homework Assignment #2 ---------------------- due Thu, Feb 10 Spacetime propagators --------------------- Field Theory book www.cns.gatech.edu/FieldTheory/05-ExtraProblems.pdf Exercise 5.A.1 Diagonalization of propagators Exercise 5.A.2 Probability conservation Exercise 5.A.3 Massless propagator Quantum Theory notes (version 3.0 of Jan 2 2005) www.cns.gatech.edu/FieldTheory/QMlectures/lectQM.ps.gz A: derive the 4-vertex momentum conservation (3.67) B: derive the 4-vertex momentum in continuum limit Bonus points: C: On a planar triangular lattice a point has 6 neighbors. Show that in the continuum limit, massless case you obtain the same propagatora as in Exercise 5.A.3 above D: www.cns.gatech.edu/FieldTheory/05-ExtraProblems.pdf Exercise 5.A.8 random walk on a Lie group manifold (for Austin) E: write up missing text of www.cns.gatech.edu/FieldTheory/QMlectures/lectQM.ps.gz Sect 3.6 Continuum theory in LaTeX, to be included in the next version Predrag Cvitanovic
