Wed 08 Oct 14:00: Modeling dissolved Pb concentrations in the Western Arctic Ocean: the continued legacy of anthropogenic pollution
Over the last century, the supply of Pb by anthropogenic pollution has strongly exceeded the natural supply to the atmosphere, altering its cycling and resulting in serious human health consequences, and making its way into the oceans. The Arctic Ocean, while remote, has not been isolated from the impacts of Pb pollution. Over the past decade, observational campaigns associated with the GEOTRACES program have greatly expanded our knowledge of Pb cycling in the Arctic Ocean and have identified that at present, dissolved Pb (dPb) concentrations in the Arctic Ocean are considered low. Nevertheless, Pb isotope signatures suggest that anthropogenic pollution impacts the Arctic Ocean. Building on the new wealth of observations, we developed the first three-dimensional model simulating dPb in Inuit Nunangat, the Western Arctic Ocean, to assess our current understanding of Pb cycling, quantify the role of anthropogenic pollution, and to use dPb as a tracer of circulation of Atlantic and Pacific water masses. With simulations from 2002-2021, we find that current and historical anthropogenic pollution account for at least 28% of dPb addition to the Western Arctic Ocean. Advected water from the Pacific and North Atlantic Oceans convey elevated pollution-derived dPb concentrations to the Arctic and play a key role, contributing 43% to the annual dPb budget. Lastly, using dPb as tracer, we track the seasonal extension of warm Atlantic Water along the West Greenland shelf where it is a potential source of heat to marine-terminating glaciers, and we trace occasional dense overflows of Atlantic Water into the deep Baffin Bay interior.

Wed 01 Oct 14:15: Symplectic pushforwards and Lagrangian classes
Fundamental examples of symplectic varieties are moduli spaces of sheaves on K3 surfaces. This can be extended to higher-dimensional Calabi-Yau varieties through the concept of shifted symplectic structures in derived algebraic geometry. In the first half of the talk, I will introduce a general operation of producing shifted symplectic stacks from given ones. Basic examples like cotangent bundles, critical loci, and Hamiltonian reduction can be understood as special cases of this operation. Moreover, this unification enables us to provide an etale local structure theorem for shifted symplectic Artin stacks. In the second half of the talk, I will provide an application to enumerative geometry. I will explain the construction of Lagrangian classes for perverse sheaves in cohomological Donaldson-Thomas theory, whose existence was conjectured by Joyce. As examples, I will explain how to construct the following structures from the Lagrangian classes: (1) cohomological field theories for gauged linear sigma models; (2) cohomological Hall algebras for 3-Calabi-Yau categories; (3) relative Donaldson-Thomas invariants for Fano 4-folds with anti-canonical divisors; (4) refined surface counting invariants for Calabi-Yau 4-folds. This is joint work in progress with Adeel Khan, Tasuki Kinjo, and Pavel Safronov.

Thu 02 Oct 14:00: Dimension lifting in quantum computation of partial differential equations and related problems
Quantum computers are designed based on quantum mechanics principle, they are most suitable to solve the Schrodinger equation, and linear PDEs (and ODEs) evolved by unitary operators. It is important to to explore whether other problems in scientific computing, such as ODEs, PDEs, and linear algebra that arise in both classical and quantum systems which are not unitary evolution, can be handled by quantum computers.
We will present a systematic way to develop quantum simulation algorithms for general differential equations. Our basic framework is dimension lifting, that transfers non-autonomous ODEs/PDEs systems to autonomous ones, nonlinear PDEs to linear ones, and linear ones to Schrodinger type PDEs—coined “Schrödingerization”—with uniform evolutions. Our formulation allows both qubit and qumode (continuous-variable) formulations, and their hybridizations, and provides the foundation for analog quantum computing which are easier to realize in the near term. We will present dimension lifting techniques for quantum simulation of stochastic DEs and PDEs with fractional derivatives, and quantum machine learning. A quantum simulation software—“UnitaryLab”—will also be introduced.
