11:00- (A616, 6th floor of the main building.)

N. Trivedi (Physics Department, The Ohio State University)
Dynamics from Quantum Monte Carlo Simulations: Part I

The first part will focus on T=0 variational methods. I will show how dynamical information about excitations can be obtained using exact sum rules and moments of the spectral function. I will apply these ideas to the superconducting state of cuprates. I will also discuss the effects of disorder on the excitation spectrum of the cuprates.

N. Trivedi (Physics Department, The Ohio State University)
Dynamics from Quantum Monte Carlo Simulations: Part II

The second part will focus on non-zero T methods: Path integral quantum Monte Carlo and Determinantal quantum Monte Carlo methods. I will show how the imaginary time information on the spin, charge and current correlations can be analytically continued 'without much sweat' to obtain the corresponding behavior of the NMR relaxation rate, the density of states and conductivity at low energies. I will apply these ideas to the BCS-BEC crossover in cold atoms with a discussion of the pseudogap behavior as well as conductivity at the SC-I transition in quench condensed films.
