The seminar “Expansion in large coordination number for the quantum Ising model” by Patrick Navez, Skoltech organized by Superconducting Metamaterials Laboratory will be held in National University of Science and Technology MISIS (Moscow, Leninskiy prospekt 4), lecture hall Б-708 (7th floor) on 1st of June at 14:00
Abstract:
Quantum lattice systems are encountered in many fields of physics: solid states, ultracold gases, quantum optics, and metamaterials. For this class of systems, we establish a set of hierarchy equations describing the non equilibrium time evolution of the n-site spatial correlation reduced density matrices and solve it iteratively through a 1/Z expansion where Z is the coordination number. As an illustration of the powerfulness of this method, we focus on the particular study of quench dynamics of the quantum Ising model. We also show the potentiality of this method to solve the Bose and Fermi-Hubbard model where the latest is likely to describe the high Tc superconductivity.
Everyone is welcome!
Entrance for seminar participants who are not students, graduate students or employees of MISIS, will be carried out upon presentation of passport subject to prior registration for the seminar (until 13:30 the day of the seminar).
