Sudhaker Upadhyay is an Indian theoretical physicist. His research focuses on black hole thermodynamics, quantum gravity, cosmology, and gauge theories. He is associated with the physics department at K. L. S. College, Magadh University.
Education and career
[edit]Sudhaker Upadhyay completed his Ph.D. in theoretical high energy physics at Banaras Hindu University (BHU) between 2008 and 2013. His doctoral research was supervised by Bhabani Prasad Mandal, focusing on BRST symmetry.[1][2]
After his Ph.D., Upadhyay held a postdoctoral position at the Indian Institute of Technology Kanpur and worked as a senior researcher at the Indian Institute of Technology Kharagpur from December 2014 to March 2016. He later joined Magadh University as an assistant professor.[2]
Research
[edit]Upadhyay's research is in the areas of theoretical physics, particularly focusing on black holes, general relativity, and quantum field theory. He has published extensively on the thermodynamic properties of various types of black holes, including those in the context of massive gravity and modified theories of gravity. His work often involves studying the effects of quantum corrections on black hole entropy and stability.[3]
Another significant area of his research is the application of BRST symmetry and anti-BRST transformations in gauge theories, a topic he explored during his doctoral studies and in subsequent work.[4]
As of 2024[update], his publications have been cited over 3,000 times.[3]
