Applied Physics/Physics Colloquium: Quantum Simulations and Tensor Networks in Condensed Matter and High Energy Physics

Quantum Simulations and Tensor Networks in Condensed Matter and High Energy Physics
Tuesday, October 31, 2017 - 4:15pm
Hewlett 200
Ignacio Cirac (Hanna Visiting Scholar, Max Planck Institute)
Abstract / Description: 

 2017-10-26Many-body quantum systems are very hard to describe, since the number of parameters required to describe them grows exponentially with the number of particles, volume, etc.  This problem appears in different areas of science, and several methods have been developed in fields of quantum chemistry, condensed matter and high energy physics in order to circumvent it in certain situations. In the last years, other approaches inspired by quantum information theory have been introduced in order to address such a problem. On the one hand, quantum simulation uses a different system in order to emulate the behavior of the problem under study. On the other, tensor networks aim at the accurate description of many-body quantum states with few parameters. In this talk, I will give a basic introduction to those approaches, and explain current efforts to use them in order to attack both condensed and high-energy physics problems.


APPLIED PHYSICS/PHYSICS COLLOQUIUM is held Tuesdays at 4:30 pm in the William R. Hewlett Teaching Center, room 200 (see map). Refreshments in the lobby of Varian Physics at 4:15 pm.

Autumn 2017/2018, Committee: Roger Blandford (Chair), Aharon Kapitulnik, Bob Laughlin, Leonardo Senatore
