Atom Optics with Giant Quantum Reflection From a Solid Surface
Quantum reflection of an atomic wave from a solid surface is caused by the attractive van der Waals force acting on the atom near the surface. The researchers had previously verified the quantum reflection of a cold neon atomic beam from a silicon surface. In this research they demonstrate the first known reflective atom-optical elements that use natural interaction of a solid surface, or attra...
متن کاملSolid tissue simulating phantoms having absorption at 970 nm for diffuse optics.
Tissue simulating phantoms can provide a valuable platform for quantitative evaluation of the performance of diffuse optical devices. While solid phantoms have been developed for applications related to characterizing exogenous fluorescence and intrinsic chromophores such as hemoglobin and melanin, we report the development of a poly(dimethylsiloxane) (PDMS) tissue phantom that mimics the spect...
متن کاملMesoscopic entanglement induced by spontaneous emission in solid-state quantum optics.
Implementations of solid-state quantum optics provide us with devices where qubits are placed at fixed positions in photonic or plasmonic one-dimensional waveguides. We show that solely by controlling the position of the qubits and with the help of a coherent driving, collective spontaneous decay may be engineered to yield an entangled mesoscopic steady state. Our scheme relies on the realizati...
متن کاملAn optics-based variable-temperature assay system for characterizing thermodynamics of biomolecular reactions on solid support.
A biological state is equilibrium of multiple concurrent biomolecular reactions. The relative importance of these reactions depends on physiological temperature typically between 10 °C and 50 °C. Experimentally the temperature dependence of binding reaction constants reveals thermodynamics and thus details of these biomolecular processes. We developed a variable-temperature opto-fluidic system ...
متن کاملHiding an elephant into a matchbox with transformation optics
Based on transformation optics, we propose an illusion device that can make objects look much smaller and different than they actually are. In particular, the device has a capability to hide a large object (like an elephant) into a small one (like a matchbox). Compared to previous proposals for illusion devices, there is no requirement for negative refractive index or for spee...
