MathQuantum

MathQuantum is a Research Training Group (RTG) focused on enabling Mathematicians to enter the world of Quantum Information Science (QIS). We are housed at IPST and funded by NSF. With MathQuantum, we are building an educational program that will blend with collaborative research, such that education and research enhance each other in a vertically integrated training group. The research draws from a set of Mathematical areas where our faculty have expertise, and advance these by tackling QIS challenges under three themes. The training includes an innovative set of activities and prioritizes interaction between undergraduate students, graduate students, postdocs, and faculty.

I had a great time at the APS Global Physics Summit, giving my talk on Fourier analysis and Hamiltonian learning for extracting Fermi-Hubbard model parameters from atomistic electronic structure calculations of Si:P devices.

I participated in the 2023 Silicon Quantum Electronics Workshop in Kyoto, Japan, with a talk on the atomistic tight-binding Hartree-Fock electronic structure formalism for dopant arrays in silicon. The full program is available here.

I am pleased to announce that I have been honored with the 2022 PML Distinguished Associate Award.

I spent ten days at the Institute of Physics at the Nicolaus Copernicus University, invited by Prof. Michał Zieliński, working and discussing joint efforts in the many-body theory of Si:P devices. I also was invited to participate in the “Nanoday meeting” (http://nanoday.fizyka.umk.pl/) with a talk.

Our paper describing GaSb band-structure models for electron density determinations from Raman measurements was accepted at J. Appl. Phys.

Viva las Vegas! I gave a talk on my recent results on SSH quantum simulations in P-doped silicon devices at the 2023 APS March meeting

My talk on the electronic structure of silicon nanostructures with a few phosphorus atoms, presented at the 2021 Silicon quantum electronics workshop, is available on Youtube at the following link: https://youtu.be/jv9b_gdJU3M

Participated virtually in the workshop in Nonequilibrium Phenomena, Nonadiabatic Dynamics and Spectroscopy in Telluride! with a talk on the electronic structure and transport in silicon nanostructures for quantum simulations and quantum computing

Excited to participate in the Second Colombian Meeting on Many-Body Quantum Simulations with a talk on quantum simulations with P-doped silicon nanostructures.

I will participate in the 2021 virtual APS march meeting and present our work on the electronic structure and transport properties of P-doped silicon nanotransistors. https://bit.ly/2N2e7aC

My presentation on the theory and simulation of silicon-based few atom transistors will be available on-demand at the upcoming virtual MRS spring/fall 2020 conference.
