The Semiclassical Approximation: Its Application to Holography and the Information Paradox
Rifath Khan
In this research, we explore the semiclassical approximation to canonical quantum gravity and how a classical background emerges from the Wheeler-DeWitt (WDW) states. By employing…

Cauchy Slice Holography: A New AdS/CFT Dictionary
Goncalo Araujo-Regado, Rifath Khan, Aron C. Wall
We investigate a new approach to holography in asymptotically AdS spacetimes, in which time rather than space is the emergent dimension. By making a sufficiently large T^2-deformat…

Circuit Complexity in Fermionic Field Theory
Rifath Khan, Chethan Krishnan, Sanchita Sharma
We define and calculate versions of complexity for free fermionic quantum field theories in 1+1 and 3+1 dimensions, adopting Nielsen's geodesic perspective in the space of circuits…
