###### Welcome to the Laboratory for the Physics of Complex Quantum Systems!

The Laboratory was established by MIPT in May of 2020. We pursue theoretical studies of the complex behavior of many-particle quantum systems with a particular focus on the phenomenon of dynamic thermalization and on the properties of strongly correlated electronic systems.

###### Dynamic thermalization

In the past two decades, experimental advances in dealing with systems consisting of 10-1000 quantum particles allowed one to probe the behavior of thermodynamically isolated many-body quantum systems. This research direction is becoming increasingly relevant as the size of the functional elements in electronics is approaching the scale of nanometers. Efforts to create quantum computers and quantum simulators are also making steady progress. The above developments have stimulated an explosion of theoretical activity on the subject of thermalization in isolated quantum systems. The theoretical challenge here is to predict the statistical behavior that actually emerges dynamically in the course of preparation and manipulation of quantum systems. Unconventional statistical behavior may become either performance-limiting or performance-enhancing factor for quantum devices.

The subject of our special expertise within the broader dynamic thermalization agenda is the dynamics of nuclear spin systems measured by the experimental technique of nuclear magnetic resonance (NMR).

###### Quantum phenomena in strongly-correlated electronic systems: high-temperature superconductors, spin- and charge-density waves

Superconductivity is a fascinating macroscopic phenomenon of essentially quantum origin. High-temperature superconductivity in cuprates is a grand challenge to the condensed matter community. Understanding its mechanism is important both for technological applications and for deepening the fundamental knowledge about condensed matter systems. It absolutely cannot be excluded that, at some point in the future, a room-temperature superconductor will be discovered. Likewise, the research on the diagnostics and manipulation of materials exhibiting spontaneously formed spin- and charge-density waves has significant and still unexploited potential for applications in electronics.

Our current investigations include (i) the interplay between superconductivity and the spontaneous modulations of electronic density, and (ii) the nonequilibrium behavior of the spin- and charge-density waves.

###### The Laboratory is funded by the program 5-100, and by grant of the Russian Science Foundation - Projeсt №17-12-01587.
