New research explores the thermodynamics of off-equilibrium systems

Almost all truly intriguing systems are ones that are far away from equilibrium—such as stars, planetary atmospheres, and even digital circuits. But, until now, systems far from thermal equilibrium couldn't be analyzed with ...

A machine-learning algorithm that can infer the direction of the thermodynamic arrow of time

The second law of thermodynamics delineates an asymmetry in how physical systems evolve over time, known as the arrow of time. In macroscopic systems, this asymmetry has a clear direction (e.g., one can easily notice if ...

The magnetization dynamics of rare-earth metals and the role of ultrafast magnon generation

Rare-earth magnetism is dominated by localized 4f electrons, relative to inner transition metals (that are mostly comprised of lanthanides) and cannot be directly excited through an optical laser pulse. As a result, ultrafast ...

Phasing quantum annealers into experiments from nonequilibrium physics

It is established that matter can transition between different phases when certain parameters, such as temperature, are changed. Although phase transitions are common (like water turning into ice in a freezer), the dynamics ...

Physicists pin down the pay off between speed and entropy

"You have to work harder to get the job done faster," explains Gianmaria Falasco, a researcher at the University of Luxembourg as he sums up the results of his latest work with Massimiliano Esposito. This will come as no ...

Toward super-fast motion of vortices in superconductors

An international team of scientists from Austria, Germany, and Ukraine has found a new superconducting system in which magnetic flux quanta can move at velocities of 10 to 15 km/s. This opens access to investigations of the ...

Seeking 'soundwaves' in the superfluid order parameter

A Swinburne University of Technology study published this week examines the propagation of energy as sound waves in a quantum gas, revealing for the first time strong variations in the nature of the sound wave as a function ...

Massive generation of metastable bulk nanobubbles in water by external electric fields

Nanobubbles can exist on solid surfaces or in bulk liquids as nanoscopic gaseous domains. The phenomenon has attracted substantial attention due to the long-time (meta)stability and potential for practical applications. ...
