The Symposium series “Quantum Theory and Symmetries” (QTS) is a biannual

meeting intended for physicists and mathematicians who are either applying

symmetries to some physical model, or are studying mathematical objects that are

relevant for physical applications.

The first Symposium of this series was held in **Goslar (1999) QTS-1**,

then it was held in **Cracow (2001) QTS-2**, **Cincinnati (2003) QTS-3**, **Varna(2005) QTS-4**,

**Valladolid (2007) QTS-5**,

**Lexington (2009) QTS-6**,

**Prague**

(2011) QTS-7,

(2011) QTS-7

**Mexico-city (2013) QTS-8**,

**Yerevan (2015) QTS-9**,

**Varna**

(2017) QTS-10,

(2017) QTS-10

**Montreal (2019) QTS-11**.

The Symposium QTS-12 was planned to be in Moscow at the Moscow Institute of

Physics and Technology in 2021, but was postponed by one year due to Covid-19,

and now is postponed to 2023, to be held in Prague at the Czech Technical

University (Department of Mathematics, Faculty of Nuclear Sciences and Physical

Engineering).

The QTS series started around the core concept that symmetries underlie all

descriptions of quantum systems. It has since evolved to a symposium on the

frontiers of theoretical and mathematical physics.

**Current topics:**

- Symmetries in String Theory, Supergravity, Quantum Gravity
- Gauge, Noncommutative, Conformal Field Theories
- Integrable Systems
- Quantum Computing, Quantum walks on graphs and lattices
- Foundations of Quantum Theory
- Quantum Optics, Coherent States, Wigner Functions
- Dynamical Systems
- Symmetries in Statistical Physics
- Symmetries in Condensed Matter Physics
- Symmetries in Nuclear, Atomic and Molecular Physics
- Symmetries in Chemistry, Biology and other Sciences

The purpose of these meetings is to review the principal developments that have

occurred in recent years, to present the main results leading to current work in the

subject in a coherent form that will be accessible to graduate students and young

researchers newly entering the domain, and to point out the most promising

directions for future research.
