What do data science and the foundations of quantum theory have to do with one another? A great deal, it turns out. The particular branch of data science known as...

Astrophysical backgrounds of gravitational waves: an overview
The astrophysical background of gravitational waves (AGWB) is composed by the incoherent superposition of gravitational wave signals emitted by resolved and unresolved astrophysical sources from the onset of stellar activity...

Quasimaps and BPS counts
The theory of quasimaps to Nakajima quiver varieties X has recently been used very effectively by Aganagic, Okounkov and others to study symplectic duality. For certain X, namely Hilbert schemes...

Witnesses of non-classicality beyond quantum theory
I discuss general argument to show that if a physical system can mediate locally the generation of entanglement between two quantum systems, then it itself must be non-classical. Remarkably, the...

Quantum preparation games
To analyze the performance of adaptive measurement protocols for the detection and quanti cation of state resources, we introduce the framework of quantum preparation games. A preparation game is a...

Strong gravitational lensing as a cosmological probe: new ways of constraining dark
Studying the smallest self-bound dark matter structure in our Universe can yield important clues about the fundamental particle nature of dark matter, and galaxy-scale strong gravitational lensing provides a unique...

Ultimate Hadron Colliders: What is feasible? What is affordable? How to maximize reach for new gauge fields?
The potential for discovering new gauge fields of nature relies upon extending the collision energy of hadron colliding beams as far as possible beyond the present 14 TeV capability of...

Anomalies in gravitational charge algebras of null boundaries and black hole entropy
I will discuss how central extensions of charge algebras in gravitational theories with null boundaries arise from an anomalous transformation of the boundary term in the gravitational action. This parallels...

Efficient simulation of magic angle twisted bilayer graphene using the density matrix renormalization group
Twisted bilayer graphene (tBLG) is a host to a variety of electronic phases, most notably superconductivity when doped away from putative correlated insulator phases. In order to understand the nature...
