TREND REU

We have research opportunities for undergraduates interested in nanoscale science and quantum simulations in Si:P devices. Quantum silicon devices integrating a few quantum dots with nearly atomically precision are promising platforms for universal quantum computing and analog quantum simulations. The student will be able to numerically investigate the electronic structure and the nonlinear transport properties of dot arrays in model devices under several gates and source/drain potentials. Undergraduates working on one of our projects will get hands-on experience in electronic structure calculations, nanoscale electron transport, and numerical simulations.

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.
