Solving Strongly Coupled Quantum Field Theory - Part 1

Note: Virtually:
Speaker: Yuan Xin, Boston University, Physics Department

When: March 25, 2020 (Wed), 02:00PM to 03:00PM (add to my calendar)

This event is part of the Departmental Seminars.

This is the part 1 of two subsequent presentations. I will focus on introducing the method and discussing a simple application on 2D real scalar theory.

Quantum Field Theory is the language that describes a wide spectrum of physics, from the fundamental matters and interactions down to the phase transition of water. However, it is notoriously hard at strong coupling regime. In this talk I will approach this question in an old Quantum Mechanical method - keep a finite number of states and diagonalize the Hamiltonian as a finite-size matrix - with our recent setup, known as the Lightcone Conformal Truncation. I will present its applications in various two dimensional examples.

Committee: Fitzpatrick, Katz, Laumann, Sushkov, Polkovnikov
