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 ...
Liquid crystals differ from isotropic fluids (fluids with similar properties in different directions) to exhibit highly anisotropic (varying properties in different directions) interactions with surfaces. In a new report ...
One idea for how the universe began is that the universe may have appeared out of nothing due to some quantum effect, such as quantum tunneling. In the 1980s, Stephen Hawking and James Hartle further elaborated on this idea ...
(PhysOrg.com) -- We like to think that we’ve got hydrogen, one of the most basic of elements, figured out. However, hydrogen can still surprise, especially once scientists start probing its properties on the most fundamental ...
Tachyons are hypothetical particles that travel at speeds greater than the speed of light. These superluminal particles, are the "enfant terrible" of modern physics. Until recently, they were generally regarded as entities ...

Materials scientists aim to use bioinspired soft robots to carry out advanced interactions between humans and robots, but the associated technology remains to be developed. For example, soft actuators must perform quickly ...
Scientists have recreated the extreme conditions at the boundary between Earth's core and its mantle, 2,900 km beneath the surface. Using the world's most brilliant beam of X-rays, they probed speck-sized samples of rock ...

Man-made earthquakes, or induced seismicity, have become an increasing concern. These events can occur during fluid injection or extraction, such as in oil or gas reservoirs, wastewater disposal, or geothermal reservoirs.
