Direct observation of coherent energy transfer in nonlinear micro-mechanical oscillators
Changyao Chen, Damián H. Zanette, David Czaplewski +2
Energy dissipation is an unavoidable phenomenon of physical systems that are directly coupled to an external environmental bath. The ability to engineer the processes responsible f…
Evolutionary optimization of a charge transfer ionic potential model for Ta/Ta-oxide hetero-interfaces
Kiran Sasikumar, Badri Narayanan, Mathew Cherukara +5
Tantalum, tantalum oxide and their hetero-interfaces are of tremendous technological interest in several applications spanning electronics, thermal management, catalysis and bioche…
Origins and optimization of entanglement in plasmonically coupled quantum dots
Matthew Otten, Jeffrey Larson, Misun Min +3
A system of two or more quantum dots interacting with a dissipative plasmonic nanostructure is investigated in detail by using a cavity quantum electrodynamics approach with a mode…
In-situ 3D Imaging of Catalysis Induced Strain in Gold Nanoparticles
Andrew Ulvestad, Kiran Sasikumar, Jong Woo Kim +9
Multi-electron transfer processes, such as hydrogen and oxygen evolution reactions, are crucially important in energy and biological science but require favorable catalysts to achi…
Unraveling the Planar-Globular Transition in Gold Nanoclusters through Evolutionary Search
Alper Kinaci, Badri Narayanan, Fatih G. Sen +4
Au nanoclusters are of technological relevance for catalysis, photonics, sensors, and of fundamental scientific interest owing to planar to globular structural transformation at an…
Rewritable Artificial Magnetic Charge Ice
Yong-Lei Wang, Zhi-Li Xiao, Alexey Snezhko +6
Artificial ices enable the study of geometrical frustration by design and through direct observation. However, it has proven difficult to achieve tailored long-range ordering of th…
