Stiefel Flow Matching for Moment-Constrained Structure Elucidation
Austin Cheng, Alston Lo, Kin Long Kelvin Lee +2
Molecular structure elucidation is a fundamental step in understanding chemical phenomena, with applications in identifying molecules in natural products, lab syntheses, forensic s…
Reflection-Equivariant Diffusion for 3D Structure Determination from Isotopologue Rotational Spectra in Natural Abundance
Austin Cheng, Alston Lo, Santiago Miret +2
Structure determination is necessary to identify unknown organic molecules, such as those in natural products, forensic samples, the interstellar medium, and laboratory syntheses.…
Guiding Dirac fermions in graphene with a carbon nanotube
Austin Cheng, Takashi Taniguchi, Kenji Watanabe +2
Relativistic massless charged particles in a two-dimensional conductor can be guided by a one-dimensional electrostatic potential, in an analogous manner to light guided by an opti…
Spiers Memorial Lecture: How to do impactful research in artificial intelligence for chemistry and materials science
Austin Cheng, Cher Tian Ser, Marta Skreta +8
Machine learning has been pervasively touching many fields of science. Chemistry and materials science are no exception. While machine learning has been making a great impact, it i…
Coulomb Drag between a Carbon Nanotube and Monolayer Graphene
Laurel E. Anderson, Austin Cheng, Takashi Taniguchi +2
We have measured Coulomb drag between an individual single-walled carbon nanotube (SWNT) as a one-dimensional (1D) conductor and the two-dimensional (2D) conductor monolayer graphe…
Coulomb drag between carbon nanotube and graphene
Jean-Damien Pillet, Austin Cheng, Takashi Taniguchi +2
We report the observation of Coulomb drag between a two-dimensional (2D) electron gas in graphene and a one-dimensional (1D) wire composed of a carbon nanotube. We find that drag o…
