Research Topics
In the Theory Division, we study a wide range of topics which arise in the context of highly controlled and complex interacting quantum mechanical systems. This encompasses three main areas:

Quantum Information
Quantum Information is concerned with studying the way in which the laws of quantum mechanics can be used to store and process information and to perform computations. In particular, the possibility of creating superpositions of classical states, and to create correlations without a classical correspondence give rise to a wide range of new phenomena in data processing and computation. Our research covers a wide range of topics in Quantum Information:

Quantum Optics
Atoms and light lie at the basis of most of the methods that are used to store, process and transmit quantum information, and the ideas developed in that field are now being implemented in other platforms. Additionally, with the development of new scenarios that combine different technologies, theoretical quantum optics is confronted with new challenges, and the possibility of discovering new phenomena. Among other, the Theory Division is carrying out research in different topics, some of them in close collaboration with experimentalists:

Quantum ManyBody Systems
Systems composed of multiple quantum components exhibit rich physical phenomena and can give rise to the most interesting macroscopic properties (e.g. hightemperature superconductivity or thermalization). Most such systems are very hard to solve, and it is of fundamental interest to develop techniques that allow us a better understanding of these phenomena. The Theory Division investigates these problems from different perspectives:
