Superconductivity and magnetism in van der Waals materials
IISER Pune Physics department invites you to a seminar hosted by Optica Student Chapter-IISER Pune Optics League
Starting with graphene, 2D materials have been of interest to electronics and optoelectronics. There is a renewed interest in topological, magnetic, and superconducting properties of 2D materials in the last few years as the systems offer unique experimental knobs. I will discuss two examples studied in our lab.
High-temperature superconductors (HTS) are essential for potential applications and for understanding the origin of strong correlations. BSCCO, a van der Waals high-temperature superconducting material (Tc of 85 K), offers a platform to probe the physics down to a unit-cell. Modifying superconductivity in HTS locally is of immense interest for superconducting electronics on a small length scale. We develop a simple route to modify superconductivity locally; this opens up avenues for new superconducting devices .
Antiferromagnetic materials are intensely studied in the last several years; layered antiferromagnets offer new opportunities. Spin-waves have been studied for data storage,communication, and logic circuits. We probe standing spin-waves in van der Waalsantiferromagnetic material, CrCl3 ; this is the first direct observation of standing spin-wave modes with optical and acoustic flavors in a van der Waals material .
I will show that this system also provides unique opportunities to study hybrid quantum systems by allowing strong magnon-magnon and magnon-photon coupling.
