## About the Q-Math Seminar

The Q-Math Seminar is a series of seminars regularly held at the Mathematics department of the Carlos III University and the ICMAT. The topics discussed usually in the seminar are related with mathematical aspects of quantum theory and include:

- Differential Geometry
- Functional Analysis
- Operator Theory
- Quantum Information Theory

## Upcoming seminars

### Alberto Ruiz de Alarcón (Universität Tübingen)

#### Matrix Product Operator Algebras

##### Tuesday the 28th of March, 2023, 13:00, Room 2.2.D08

Understanding the entanglement structure of quantum many-body systems is one of the driving forces in theoretical physics nowadays. In particular, this has led to the use of tensor networks, the central objects of this talk. We will discuss how representations of well-known algebraic structures, e.g. weak Hopf algebras, give rise to algebras of one-dimensional tensor networks exhibiting exotic properties, known as Matrix Product Operator Algebras. We will show how to transfer results between both the algebraic and the tensor network settings and how these tools can be applied to describe Kitaev's quantum double models or classify quantum phases of matter in the open regime.
