The ability to control and manipulate the magnetic properties of solid-state systems has formed the basis of technological applications, such as information storage, for several decades. However, at the basis of the magnetism observed in materials is a quantized unit of magnetic moment — the “spin” of an atom or electron.
The study of this quantum aspect forms the basis of several research fields, such as spintronics and quantum information processing. Professor Ghosh’s current research involves studying spin dynamics in different systems, using ultra-fast time-resolved spectroscopic techniques. In particular, her lab focuses on:
- Spin coherence in optical microcavities using electron-photon feedback for processing and communication of quantum information
- Novel dilute magnetic semiconductors, which would combine the functionalities of information storage capabilities of magnetic materials with the logic processing of semiconducting circuitry
- Optical control of macroscopic spin clusters in low-dimensional magnetic systems to control effective couplings between magnetic degrees of freedom
