The Condensed Matter and Surface Physics Group at the Saha Institute of Nuclear Physics (SINP) explores a broad landscape of quantum and nanoscale phenomena in both “hard” and “soft” condensed matter systems. We seek to understand how reduced dimensionality, interfacial environments, and nanoscale confinement and structural nuances give rise to emergent electronic, magnetic, and optical behaviors—insights that directly impact next-generation microelectronics, optoelectronics, and nanobiotechnology.

Our work centers on low-dimensional and interface-engineered materials, spanning epitaxial thin films, 2D van der Waals systems, moiré heterostructures, self-assembled organic layers, and nanoparticles. We study molecular ordering and interfacial dynamics in organic, polymeric, and hybrid films, as well as the electronic, optical, and magnetic responses of 2D electron gases and quantum materials. In essence, we probe the phenomena that arise under extreme confinement and at ultra-low temperatures.

These investigations are enabled by a comprehensive suite of growth and nano-fabrication tools, including MBE, CVD, ion and cluster deposition, electron-beam lithography, ion-beam milling, and self-assembly, supported by advanced characterization platforms such as ARPES, LEEM-PEEM, TEM, PPMS, cryogen-free systems, and a dilution refrigerator.

Together, our efforts create a vibrant research environment where cutting-edge experiments meet fundamental questions, enabling transformative discoveries at the frontiers of quantum materials, nanoscience, and surface physics.
