Complexity and Randomness in the Dynamics of Quantum Systems
This thesis explores two complementary facets of quantum dynamics: the growth of operator complexity in open quantum systems and the certification of quantum randomness from temporal correlations in single-qubit dynamics. ... -
Dipole Cosmology: Revisiting Our Universe with a Flow
In this thesis, we explore an ansatz alternative to the FLRW classes of spacetimes for our Universe, in light of observations that exhibit anisotropies at late times. Despite the existence of these anisotropies beyond ... -
New Dispersive Techniques for Quantum Field Theories
Quantum field theory has been remarkably successful in describing interactions of elementary particles, particularly through perturbative methods. However, many important regimes — including strong coupling and quantum ... -
Thermal one point functions in large $N$ vector models and holography
This thesis develops analytic methods to evaluate thermal one point functions in holography and a class of conformal field theories(CFT) described by large $N$ vector models. For planar charged black holes in $AdS_{d+1}$ ...
