The talk will present progress towards a microscopic understanding of the entropy of rotating BPS black holes in AdS. I will describe a new BPS limit of black hole thermodynamics which first focuses on a supersymmetric family of complexified solutions and then reaches extremality. In this limit the chemical potentials obey a constraint that is interpreted as a regularity condition in the...

Based on Nielsen’s geometric approach, the variation of holographic complexity for two nearby target states only depends on the end point of the optimal trajectory, a result designated as the first law of complexity. As an example, we will examine the complexity=action conjecture when the AdS vacuum is perturbed by a scalar field excitation, which corresponds to a coherent state.

Computational complexity is a quantum information concept that recently captured increasing attention in gravitational holography. In particular, the complexity=volume (CV) and complexity=action (CA) conjectures have been proposed as gravitational duals of quantum computational complexity. In this talk I will discuss these holographic conjectures and their subregion generalizations in a few...
