Quasiparticle GW for Superconductors: Toward a Unified Treatment of Electron-Phonon and Electron-Plasmon Couplings
Catalin D. Spataru, Christopher Renskers, Elena R. Margine
Superconducting two-dimensional materials, and in particular few-layer graphene, offer an exciting platform for low-power electronics, yet the origin of their unconventional superc…
Semiconductor Meta-Graphene and Valleytronics
Praveen Pai, Aron W. Cummings, Alexander Cerjan +3
Nano-patterned semiconductor interfaces offer a versatile platform for creating quantum metamaterials and exploring novel electronic phenomena. In this study, we illustrate this co…
Enhancement of hydrogen absorption and hypervalent metal hydride formation in lanthanum using cryogenic ball milling
Sakun Duwal, Vitalie Stavila, Catalin Spataru +11
Rare earth superhydrides exhibit high temperature superconductivity but are difficult to characterize and use in applications due to their high formation and stability pressures, w…
Lithography defined semiconductor moires with anomalous in-gap quantum Hall states
Wei Pan, D. Bruce Burckel, Catalin D. Spataru +16
Quantum materials and phenomena have attracted great interest for their potential applications in next-generation microelectronics and quantum-information technologies. In one espe…
Topological phenomena in artificial quantum materials revealed by local Chern markers
Catalin D. Spataru, Wei Pan, Alexander Cerjan
A striking example of frustration in physics is Hofstadter's butterfly, a fractal structure that emerges from the competition between a crystal's lattice periodicity and the magnet…
