Sample interview questions: Have you used any computational techniques to study quantum field theory?
Sample answer:
Yes, I have used various computational techniques to study quantum field theory.
1. Lattice Gauge Theory:
– Represented gauge fields on a discrete lattice grid, reducing the continuous field theory to a finite-dimensional system.
– Used Monte Carlo simulations to calculate physical quantities such as particle masses and decay rates.
2. Path Integral Monte Carlo:
– Formulated the path integral formalism of quantum mechanics in a Monte Carlo framework.
– Calculated Green’s functions and other key quantities to study thermodynamics and phase transitions in quantum field theories.
3. Functional Renormalization Group Equation:
– Developed a non-perturbative approach to calculate the effective action of a quantum field theory.
– Used numerical techniques to solve the renormalization group equations, prov… Read full answer
