CENTER FOR QUANTUM MATERIALS AND CONDENSED MATTER PHYSICS SEMINARS

During Spring 2021, seminars will be posted on this calendar and take place via Zoom. To join the mailing list and get the link, email Jennifer Cano (first name.lastname@stonybrook.edu)

The CQM Distinguished Lecture series has been established in the Fall of 2015 to bring to Stony Brook University the renowned experts in the physics of quantum matter.

The lectures in this series will attract a broad audience of physicists from SBU and BNL,
and SBU graduate students.

Quantum materials under the nonlinear electromagnetic spotlight 

Close to large masses, the geometry of space-time warps, bending the light trajectory and leading to dramatic phenomena like black holes and gravitational waves. The quantum world of electrons likewise has a geometrical structure, constructed from electronic quantum wave functions. Such a quantum geometrical structure, studied as quantum metric and Berry curvature, can reshape an electron’s behaviors in nontrivial ways [1]. Quantum geometry also has a deep relation with topological phases of matter, which have taken center stage in condensed matter over the past decade. Although many topological phases have been experimentally discovered in quantum materials, the understanding of how bulk quantum geometry is manifest in material properties has remained limited. In this talk, I will show several examples in 2D layered materials how quantum geometry can strongly modify the electronic response to external electromagnetic waves and give rise to a wide range of previously unexplored nonlinear responses [2-3].
