Photos show what the Arecibo telescope looked like before and after its disastrous collapse

Images show the Arecibo Observatory telescope's collapse. NAIC Arecibo Observatory/NSF, Ricardo Arduengo/AFP/Getty Images The Arecibo Observatory's radio telescope collapsed Tuesday morning, when its 900-ton suspended platform crashed into the enormous dish below. Arecibo was one of Earth's best radio astronomy tools for 57 years. Its death is a blow to asteroid-tracking efforts and the hunt for alien life. Photos of the iconic telescope show what it looked like before and after the cr...

Natural three-dimensional nonlinear photonic crystal

Nonlinear photonic crystals are playing a prominent role in laser and nonlinear optics. Here, Scientists in China presented a natural potassium-tantalate-niobate (KTN) nonlinear photonic crystal with 3D Rubik's domain structures. The composite rotated domains could be useful for different phase-matching conditions with rich reciprocal vectors along arbitrary direction. KTN crystal breaks strict requirements for incident light and crystal direction in nonlinear optics and trigger newfangled optoe...

Attosecond interferometry in time-energy domain

Analogous to the conventional spatial double-slit experiment, the time domain Young's experiment can be realized by using temporal slits for diffraction instead, and fringes in the energy domain are expected. As a time-energy domain interferometric device, the temporal Young's interferometer is anticipated to possess advantageous time resolving capability and holds the promise of tracking ultrafast processes. Scientists from China developed an all-optical attosecond few-slit interferometer and d...

New physical picture leads to a precise finite-size scaling of (3+1)-dimensional O(n) critical system

Logarithmic finite-size scaling of O(n) critical systems at upper critical dimensionality has been a long-standing issue. Recently, scientists based in China and US provided a new physical picture. On this basis, they established an explicit scaling form for the free energy density, which simultaneously consists of a scaling term for the Gaussian fixed point and another term with multiplicative logarithmic corrections. They found that the finite-size critical two-point correlation exhibits a two...

Ideal type-II Weyl points are observed in classical circuits

As one kind of elementary particles, Weyl fermions manifest themselves as Weyl points from dispersion relations. Although the type-II Weyl points with strongly tilted band structures have been observed in different systems, their ideal form where the Weyl points are symmetry-related and well-separated, and reside at the same energy and far from nontopological bands are never observed. Now scientist based in China and Singapore observe the ideal type-II Weyl points in classical circuits.
