Twisted 2D-Materials

As part of the Superpuddles Lab, the Twisted 2D Materials Group focuses on two-dimensional superconducting nanodevices, exploring how light couples to lattice vibrations, spin textures, and electronic degrees of freedom in atomically thin materials. By combining ultraclean fabrication, twisted van der Waals heterostructures, and advanced optical and electrical probes, the group seeks to uncover new light–matter phenomena and translate them into functional quantum optoelectronic devices.
