Entangled Photon Correlations Allow a Continuous-Wave Laser Diode to Measure Single Photon, Time-Resolved Fluorescence

Kavli Affiliate: Scott K. Cushing | First 5 Authors: Nathan Harper, Bryce P. Hickam, Manni He, Scott K. Cushing, | Summary: Fluorescence lifetime experiments are a standard approach for measuring excited state dynamics and local environment effects. Here, we show that entangled photon pairs produced from a continuous-wave (CW) laser diode can replicate pulsed laser […]

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 […]

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, […]
