Topological Stars in Gravity - Understanding Black Hole Microstates

Explore the fascinating intersection of string theory and gravity in this physics seminar presented by Dr. Ibrahima Bah from John Hopkins University. Delve into the microscopic degrees of freedom in gravity and discover how certain quantum mechanical states can be described through classical Einstein gravity. Learn about the construction of coherent states through the addition of topological structures in spacetime using compact extra dimensions, leading to the formation of ultra-compact objects known as topological stars. Understand the significance of these objects in modeling black hole microstates and their relevance in the contemporary era of black hole astrophysics.
