Associate Professor

**Center for Photonics and Quantum Materials**

Boris is a theoretical physicist specializing in the field of Solid-State Physics. His research interests include solid-state nuclear magnetic resonance, high-temperatures superconductivity, and a broader set of topics associated with the foundations of quantum statistical physics and the role of chaos in many-particle systems.

Boris graduated from the Moscow Institute of Physics and Technology in 1994. In 2000, he obtained his Ph.D. degree from the University of Illinois at Urbana-Champaign, where his Ph.D. advisor was Prof. A. J. Leggett. Boris’ subsequent career included postdoctoral positions at Utrecht University, Max Planck Institute for the Physics of Complex Systems in Dresden, and University of Tennessee-Knoxville/Oak Ridge National Laboratory. In 2008-2013, he was the leader of Young Investigators Group “Quantum Dynamics and Complex Quantum Systems” at the University of Heidelberg. In the academic year of 2013-2014, Boris worked as a professor at the Nazarbayev University in Astana, Kazakhstan. He joined Skoltech in July of 2014. Concurrently, Boris holds a position of a guest professor at the University of Heidelberg.

Besides physics research, Boris also has experience in the sphere of education management. In 1991, he founded and, until 1994, was the director of PhysTech College, a center for extra-curricular studies of mathematics, physics and English for high-school students, that has since expanded to become one of Russia’s largest network of educational centers called “Unium”.

**Introduction to Solid State Physics**

Number of ECTS credits: 6

Course Classification: Science, Technology, and Engineering

Course Description:

The course will introduce students to the basic notions of solid-state physics such as: periodic crystal lattices, phonons, Bloch theorem, properties of electronic bands in metals, semiconductors and insulators, conduction properties of various materials, the notion of Fermi-surface in metals, and magnetic phase transitions. Dependent on the level of the students, the course may also touch the topics of disordered solids, superconductors, and advanced experimental techniques. Upon availability, the course may include several laboratory experiments.

The course is intended for students who either never had a solid-state physics course or feel the need to strengthen the foundations of the subject. It is to be assumed that students previously had basic courses of quantum mechanics and statistical physics, but the relevant knowledge will be reintroduced whenever necessary.

The course will have a character of review. Lectures will cover the most important aspects of every topic, leaving a significant fraction of material for self-study and homework.

Intended Learning Outcomes:

Become fluent in the basic concepts of solid-state physics

Understand the approximate character of these concepts and recognize their applicability limits.

Get practical experience to the framework of basic solid-state models.

Improve their skills in applications of quantum mechanics and statistical physics.

**Advanced Solid State Physics**

Number of ECTS credits: 6

Course Classification: Science, Technology, and Engineering

Course description:

The course is a part of the educational program in quantum materials. It can also be chosen as an elective for the programs in photonics and material science.

Prerequisites:

Basic knowledge of quantum mechanics and statistical physics;

Recommended courses: Course «Introduction to Solid-State Physics», or a comparable course.
