Quantum open systems and the canonical models of decoherence

[CANCELLED] Program in Applied Mathematics Brown Bag Seminar

Quantum open systems and the canonical models of decoherence
Series: Program in Applied Mathematics Brown Bag Seminar
Location: ONLINE
Presenter: Alberto Acevedo, Program in Applied Mathematics, University of Arizona

Quantum mechanics is a formalism used to address many physical phenomena, light, phase changes of matter, atomic dynamics etc. However, the environment in which such a system lives and the corresponding interactions between the system and such an environment are often ignored. Quantum open systems provide a frame work for studying quantum systems which are coupled to some environmental degrees of freedom in a non-negligible way. We will look at the four principle types of quantum open systems that one might encounter in the physical world. i.e. Boson-Boson, Boson-Fermion, Fermion-Boson and Fermion-Fermion System-Environment pairs. After developing such quantum open system’s models we will discuss the relationship between what is known as ”quantum decoherence” and quantum open systems. If time permits we will touch on some pitfalls that arise when dealing with quantum open systems presenting a system with continuous spectrum.
