Light matter interactions: The first exciting thing in nature is the light which enable us to see everything in our surrounding. The light reflects, refracts, scatter, superpose and showcase exciting optical phenomena. Light also interacts with the materials and provide a significant insightful information. Understanding light-matter interactions is crucial for optics, telecommunications, solar energy, spectroscopy, and quantum technologies. We exploit these interactions to understand the many body physics, electron photon and phonon interactions to develop new technologies with improved functionality and performance. 

Quantum Materials and Devices: Quantum materials and devices are an integral part of the field of quantum technology, which aims to harness the principles of quantum mechanics to perform tasks that would be otherwise impossible or impractical using classical methods. These materials and devices play a crucial role in various applications, including quantum computing, quantum communication, and quantum sensing. Advances in quantum materials and devices are at the forefront of modern research, and they hold the potential to revolutionize various industries, including computing, telecommunications, and sensing. However, there are still many technical and scientific challenges that need to be overcome before these technologies become widespread. 

Thermoelcctric Materials: Thermoelectric materials are a class of materials that have the ability to convert heat energy into electrical energy (the Seebeck effect) or vice versa (the Peltier effect). This property makes them crucial for a range of applications, from power generation in space missions to waste heat recovery in industrial processes. Efforts are ongoing to discover and engineer new thermoelectric materials with improved properties and to develop scalable manufacturing techniques to make them more economically viable for widespread applications. 

Carbon Materials and Functional Devices: Carbon materials refer to a diverse group of substances primarily composed of carbon atoms. Due to their unique properties, they find applications in a wide range of fields, including electronics, energy storage, aerospace, and biomedical engineering. Carbon materials continue to be a focus of intense research due to their versatility and potential for revolutionizing various industries. Their unique properties make them an integral part of modern technology and hold promise for future innovations.
