Director of LBNL’s Microscopic and Electronic Structure Observatory (MAESTRO), a dedicated ARPES beamline, Dr. Rotenberg’s research interests are the relationship between electronic structure and morphology, symmetry, and dimensionality, and the impact of many-body interactions on the ground states of low dimensional materials such as graphene, metal and oxide surfaces.
Our laboratory integrates scanning probe microscopy and fabrication of custom materials and nanodevices. We aim to advance knowledge of physical phenomena that emerge as a result of low dimensionality, presence of surfaces and interfaces, and proximity between different states of matter.
Studies of light-matter interaction in quantum confined systems have provided great insight into diverse and fundamental problems such as many-body interactions and quantum entanglement. We use and develop a variety of optical spectroscopy tools such as correlated single photon counting, Brillouin light scattering, and multidimensional ultrafast spectroscopy to probe electron dynamics in nanostructures.
Prof. Iwasa has been working on 2D superconductivity induced by ionic gating, and is currently interested in the symmetry control and related physical
properties of 2D and related materials, which includes electronic phase
transitions, valleytronics, nonlinear transport properties, and optoelectronic
The Jarillo-Herrero group is currently focused on quantum transport and quantum optoelectronic measurements in low dimensional materials and their combined hybrids, with special emphasis on investigating their superconducting, magnetic, and topological properties.
My research interests lie in the area of quantum condensed matter
physics, primarily superconductivity and strongly correlated systems.
