Numerical simulations characterize 'matrix tides' and other complex wave patterns seen in Qiantang River During 2024, onlookers observed a startling sight on China's Qiantang River: waves forming a grid-like pattern. Dubbed the "matrix tide," this complex wave pattern was caused by the river's famed tidal bores that surge upstream against the current. Specifically, two shockwave-like tidal bores, known as undular bores, spread along two different directions like ripples on a pond and collided with each other. /news/2025-08-numerical-simulations-characterize-matrix-tides.html Mathematics Wed, 13 Aug 2025 10:50:03 EDT news674301001 The first experimental realization of quantum optical skyrmions in a semiconductor QED system Skyrmions are localized, particle-like excitations in materials that retain their structure due to topological constraints (i.e., restrictions arising from properties that remain unchanged under smooth deformations).
