Giant Optomechanical Coupling in the Charge Density Wave State of Tantalum Disulfide
Anubhab Haldar, Cristian L. Cortes, Stephen K. Gray +2
We study the coupling of light and the structural order parameter in the charge density wave (CDW) state of the layered transition-metal dichalcogenide, Tantalum Disulfide ($1T-\ma…
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…
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…
Describing the diverse geometries of gold from nanoclusters to bulk-- a first-principles based hybrid bond order potential
Badri Narayanan, Alper Kinaci, Fatih G. Sen +4
Molecular dynamics simulations using empirical force fields (EFFs) are crucial for gaining fundamental insights into atomic structure and long timescale dynamics of Au nanoclusters…

Surface plasmons at single nanoholes in Au-films
L. Yin, V. K. Vlasko-Vlasov, A. Rydh +7
The generation of surface plasmon polaritons (SPP's) at isolated nanoholes in 100 nm thick Au films is studied using near-field scanning optical microscopy (NSOM). Finite-differenc…
