Mohammad Enayati, Ph.D., is a Resident Researcher at Razi University where he received his Ph.D. in theoretical physics in 2017. His research interests include group-theoretical methods in physics, with an emphasis on de Sitter (spacetime) symmetry considerations on both classical and quantum levels.Jean-Pierre Gazeau, Ph.D., is an Emeritus Professor at the University Paris Cité. He was chairman of the Standing Committee of the International Colloquium on Group Theoretical Methods in Physics from 2006 to 2014. He obtained his academic degrees from Sorbonne University and Pierre-and-Marie Curie University. He has authored more than 230 scientific publications, including three books, in theoretical and mathematical physics, mostly devoted to group theoretical methods in physics, coherent states, quantization methods, and number theory for aperiodic systems.Hamed Pejhan, Ph.D., is a Postdoctoral Fellow at Zhejiang University of Technology He received his degree in mathematical physics from Azad University in 2015. His scientific interests revolve around the application of group theoretical methods in physics, with particular attention to developing a consistent formulation of quantum elementary systems in (anti-)de Sitter spacetime.Anzhong Wang, Ph.D., is a Professor in the Physics Department at Baylor University. His research interests include quantum cosmology and black holes; gravitational waves and their applications to cosmology; and classical and quantum theories of gravity and their applications to astrophysics and cosmology. He has published more than 260 articles and received approximately 8,000 citations.
