# SPECIAL JQI/QuICS SEMINAR: Dynamics after quantum quench in long-range field theories

June 8, 2015 - 11:00am
Speaker:
In this talk I will first introduce classical and quantum long-range Ising models and their field theory counterparts. I will show that in particular regimes these systems can be described with simple free non-local field theories with dispersion relation $\omega(k)=|k|^{\alpha/2}$. Having this motivation in mind I will first study many quantum aspects of free non-local field theories such as: the entanglement entropy, dynamics of local operators and entanglement entropy after quantum quenches. Then in particular cases I will also  present some results  regarding interacting field theories.
