The experimental demonstration of topological dissipation in photonic resonators
So far, physicists have primarily studied topological phases in conservatively coupled systems. These are systems with dynamics that do not dissipate and a phase space that does not shrink over time. They are in stark contrast with dissipative system.....»»

NASA will join a military program to develop nuclear thermal propulsion
None of this will happen quickly. The technology is difficult and unproven. Enlarge / Artist concept of Demonstration for Rocket to Agile Cislunar Operations (DRACO) spacecraft. (credit: DARPA) Nearly three years ago, th.....»»
Researchers derive a unified topological speed limit for the evolution of physical states
Physical systems evolve at a particular speed, which depends on various factors including the system's so-called topological structure (i.e., spatial properties that are preserved over time despite any physical changes that occur). Existing methods f.....»»
Photonic hopfions: Light shaped as a smoke ring that behaves like a particle
We can frequently find in our daily lives a localized wave structure that maintains its shape upon propagation—picture a smoke ring flying in the air. Similar stable structures have been studied in various research fields and can be found in magnet.....»»
First observation of the Cherenkov radiation phenomenon in 2D space
Researchers from the Andrew and Erna Viterbi Faculty of Electrical and Computer Engineering at the Technion—Israel Institute of Technology have presented the first experimental observation of Cherenkov radiation confined in two dimensions. The resu.....»»
New optical method to verify topological phases in magnetic materials
Topological phases are not restricted to electronic systems. They can also occur in magnetic materials whose properties are described in terms of magnetic waves—or so-called magnons. However, even though scientists have established techniques to ge.....»»
The first experimental bosonic stimulation of atom-light scattering in an ultracold gas
Bosons, one of the two fundamental classes of particles, have been the focus of countless physics studies. When bosonic particles are transitioning into an already occupied final quantum state, the rate of this transition is enhanced by its so-called.....»»

Review of photonics based on Weyl semimetals
Weyl semimetals are topological materials whose low-energy excitations obey the Weyl equation. In a Weyl semimetal, the conduction and valence bands touch at discrete points in momentum space called Weyl nodes. Weyl nodes are monopoles of the Berry c.....»»
Researchers realize the quantum simulations of topological phase transitions
Topology refers to the overall property that remains unchanged despite continuous local modifications. A coffee cup and a donut are no different to mathematicians because they have the same topological charge. Materials with various topological charg.....»»
