Engineering cubic quantum nondemolition Hamiltonian with mesoscopic optical parametric interactions

Kavli Affiliate: Alireza Marandi | First 5 Authors: Ryotatsu Yanagimoto, Rajveer Nehra, Edwin Ng, Alireza Marandi, Hideo Mabuchi | Summary: We propose a scheme to realize cubic quantum nondemolition (QND) Hamiltonian with optical parametric interactions. We show that strongly squeezed fundamental and second harmonic fields propagating in a $chi^{(2)}$ nonlinear medium effectively evolve under a […]

Correlated Terahertz phonon-ion interactions dominate ion conduction in solid electrolyte Li0.5La0.5TiO3

Kavli Affiliate: Scott K. Cushing | First 5 Authors: Kim H. Pham, Kiarash Gordiz, Jonathan M. Michelsen, Hanzhe Liu, Daniele Vivona | Summary: Ionic conduction in solids that exceeds 0.01 S/cm is predicted to involve collective phonon-ion interactions in the crystal lattice. Here, we use theory and experiment to measure the contribution of possible collective […]

AI-aided Geometric Design of Anti-infection Catheters

Kavli Affiliate: Paul W. Sternberg | First 5 Authors: Tingtao Zhou, Xuan Wan, Daniel Zhengyu Huang, Zongyi Li, Zhiwei Peng | Summary: Bacteria can swim upstream due to hydrodynamic interactions with the fluid flow in a narrow tube, and pose a clinical threat of urinary tract infection to patients implanted with catheters. Coatings and structured […]

Single-test evaluation of directional elastic properties of anisotropic structured materials

Kavli Affiliate: Chiara Daraio | First 5 Authors: Jagannadh Boddapati, Moritz Flaschel, Siddhant Kumar, Laura De Lorenzis, Chiara Daraio | Summary: When the elastic properties of structured materials become direction-dependent, the number of their descriptors increases. For example, in two-dimensions, the anisotropic behavior of materials is described by up to 6 independent elastic stiffness parameters, […]
