Topological quantum phases cannot be characterized by Ginzburg–Landau type order parameters, and are instead described by non-local topological invariants. Experimental platforms capable of realizing such exotic states now include synthetic many-body systems such as ultracold atoms or photons. Unique tools available in these systems enable a new characterization of strongly correlated many-body states.
Quantum defects in diamond provide a non-invasive, high-resolution image (right) of the magnetic field produced by a single tumor cell immersed in a sample of human blood. Conventional optical imaging (left) cannot detect the tumor cell because the blood scatters and absorbs light. Magnetic fields pass unaffected through the blood, allowing the magnetically sensitive quantum defects to detect the tumor cell. (Image credit: Walsworth Group/Harvard)

For years, camera-makers have sought ways to avoid chromatic aberration - the color fringes that occur when various wavelengths of light focus at different distances behind a lens.
The upcoming Evolved Laser Interferometer Space Antenna could help verify string theory's predictions of gravity waves. Three spacecraft will orbit around the sun and measure tiny ripples in space-time via sensitive lasers [credit: AEI/MM/EXOZET]. Inset: A 2D slice of the 6D Calabi-Yau quintic manifold. Andrew J.
