The advent of high-throughput sequencing led to breakthroughs in microbiome analysis and to an explosion of bacterial genomes being released in public repositories. However, many microbiotas cannot be cultured in the lab without introducing drastic changes in the underlying bacterial communities... read more

Electrochemistry is central to many applications such as water purification, membrane separation, sensors, energy storage and conversion systems. Among different electrochemical systems, energy storage (e.g., batteries) and conversion (hydrogen generation) systems that could harvest energy from... read more

The direct detection of Gravitational Waves with kilometer-scale laser interferometers has begun to pay dividends on the decades of both theoretical and instrumental research invested in their development. After spectacularly detecting the first known Binary Black Hole coalescence in September 2015... read more

Dvořák and Postle introduced DP-coloring to answer a question of Borodin on list-coloring of planar graphs. Formally, a DP-$$k$$-coloring of a graph $$G$$ is not exactly a coloring, but is an independent set in an auxiliary graph $$H(G,k)$$. However, DP-coloring has many properties... read more

More than 30 years ago Richard Feynman suggested the possibility of using quantum computers to simulate quantum physics. Now the technologies necessary to realize this vision are finally emerging. Particle physicists are already trying to apply quantum computing to gain a better understanding of... read more

Impurities can be a huge boon in the study of electronic properties of quantum matter. A known impurity placed in a host material can say a lot about the ground state of the host; conversely, the nature of impurities can be accurately deduced by studying how they behave in a well understood... read more

Department of Applied Mathematics - Lecture - Hermann Hall Ballroom
Motivated by a few concrete examples such as bird flocking, congestion for crowd motion, and bee swarming, we introduce the mean field game paradigm; and we present the underpinnings of the original analytic approach based on partial differential equations, and the probabilistic approach based on... read more

We posit a new form of the optimal control of stochastic differential equations of McKean-Vlasov type (often called Mean Field Control), and we derive the corresponding Pontryagin maximum principle. This requires calculus over the Wasserstein space of probability measures. We contrast the resulting... read more

It has been suggested that the north-polar hexagon found on Saturn is an unusual Rossby wave. If this is to be the case, one must not only explain how a Rossby wave can be hexagonal in shape, albeit with curved corners, but also why it is hexagonal rather than in the form of some other polygon. It... read more

The Poisson-Boltzmann Equation (PBE) is a widely used implicit solvent model for the electrostatic analysis of solvated biomolecules. The numerical solution of the PBE is known to be challenging, due to the consideration of discontinuous coefficients, complex geometry of protein structures,... read more
