OVERVIEW

The IX International Symposium on
**Quantum Theory and Symmetries** (QTS-9),
organized by the International Center for Advanced Studies and Physics Department of Yerevan State University,
in collaboration with the Joint Institute for Nuclear Research (Dubna, Russia) will be held in Yerevan, Armenia on July 13-18, 2015.
The QTS Symposium forthshadows the approaching
the 60th anniversary of Joint Institute for Nuclear Research .

The QTS is one of the traditional conference series taking place each odd years and brinding together the physicist and mathematicians working on the topics of symmetry, including the geometrical methods (classical and non-commutative), groups theory, Lie and nonlinear algebras, in the framework of its possible application in modern quantum physics.

The first QTS Symposium was held in Goslar in 1999 and afterwards continued in Krakow (2001), Cincinnati (2003), Varna (2005), Valladolid (2007), Lexington (2009), Prague (2011) and Mexico City (2013).

The preliminary programm of the QTS-9 Symposium in Yerevan will cover the following
**topics:**

- Foundations of Quantum Physics
- Integrable and Superintegrable models
- Supersymmetry in Quantum Mechanics and Field Theory
- Superstrings, Cosmology and Quantum gravity
- Nonlinear Quantum Theory and nonlinear Symmetries
- Quantum Optics and Coherent States
- Quantum Computing, Information and Control
- Symmetries in particle, nuclear, atomic and molecular physics
- Symmetries in Condensed Matter Physics and Statistical Physics
- Symmetries in Chemistry, Biology and other Sciences
