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...

Signals of a Quantum Universe
The idea that structure in the Universe was created from quantum mechanical vacuum fluctuations during inflation is very compelling, but unproven. Finding a test of this proposal has been challenging...

Weak approximate unitary designs and applications to quantum encryption
Unitary t-designs are the bread and butter of quantum information theory and beyond. An important issue in practice is that of efficiently constructing good approximations of such unitary t-designs. Building...

Nuclear Physics Uncertainties and Kilonovae
The observation—in light and gravitational waves—of the first neutron star merger, GW170817, provided an amazingly detailed view of these systems. Among the many successes from this single event was the...

Toric mirror symmetry via GIT windows
Every toric variety is a GIT quotient of an affine space by an algebraic torus. In this talk, I will discuss a way to understand and compute the symplectic mirrors...
