Physics - Colloquium

I discuss three new methods for the quantum many-body problem.  The first is the pinhole trace algorithm for first principles calculations of nuclear thermodynamics.  I present lattice Monte Carlo results for the phase diagram of symmetric nuclear matter.  The second is the eigenvector continuation method for extrapolation and interpolation of quantum wave functions.  I will show how it can be used as a fast emulator for quantum many-body calculations and a resummation method for divergent perturbative expansions.  The third is the rodeo algorithm for quantum computing.  This method is able to construct general eigenvectors of quantum Hamiltonians as well as the energy spectrum, transition matrix elements, and linear response functions.


Dean Lee is a Professor of Physics at the Facility for Rare Isotope Beams and Department of Physics and Astronomy at Michigan State University. His research interests include superfluidity, nuclear clustering, nuclear structure from first principles calculations, ab initio scattering and inelastic reactions,
and properties of nuclei as seen through electroweak probes. He also works on new technologies and computational paradigms such as eigenvector continuation, machine learning tools to find hidden correlations, and quantum computing algorithms for the nuclear many-body problem.


The ZOOM link will be sent on Wednesday morning to the Physics Faculty, Graduate Student, PDRA, and AP mailing lists. If you are not on one of those lists and are interested in attending, please email Suzanne Hallihan at for the link.
