Investigating the Ising model with magnetization

Researchers have explored the evolution of systems of interacting spins, as they transition from random to orderly alignments. Through new simulations, they show that this evolution can be investigated by measuring the changing ...

AI-enabled portable e-nose sniffs out harmful molecules

Consider this—there is no cheap, at-home device that can tell you milk has gone bad faster than your nose. One whiff and you know that the milk has gone rancid. Humans have created technologies that allow us to see distant ...

Team develops a solution for temporal asymmetry

Life, from the perspective of thermodynamics, is a system out of equilibrium, resisting tendencies towards increasing their levels of disorder. In such a state, the dynamics are irreversible over time. This link between the ...

Âé¶¹ÒùÔºicists develop powerful alternative to dynamic density functional theory

Living organisms, ecosystems and the planet Earth are, from a physics point of view, examples of extraordinarily large and complex systems that are not in thermal equilibrium. To physically describe non-equilibrium systems, ...

Advanced X-ray technique unveils fast solid-gas chemical reaction pathways

For the rational design of new material compounds, it is important to understand the mechanisms underlying their synthesis. Analytical techniques such as nuclear magnetic resonance and spectroscopy are usually employed to ...

Hot electron electrochemistry with ultrafast laser pulses

Laser-induced electrochemical deposition of metals on metals relies possibly on thermal and defect generation effects. When semiconductor substrates are chosen, locally photogenerated electrons can reduce metal ions resulting ...

New model of quark-gluon plasma solves a long-standing discrepancy between theory and data

Research in fundamental science has revealed the existence of quark-gluon plasma (QGP)—a newly identified state of matter—as the constituent of the early universe. Known to have existed a microsecond after the Big Bang, ...

Single-electron devices could manage heat flow in electronic components

RIKEN physicists have fabricated a nanoscale "heat engine" that uses a property of electrons known as spin as the effective working medium. It is promising for exploring the development of spintronic heat engines capable ...

The Kibble-Zurek mechanism for nonequilibrium phase transitions

The Kibble-Zurek (KZ) mechanism, confirmed experimentally only for equilibrium phase transitions, is also applicable for non-equilibrium phase transitions, as is now shown by Tokyo Tech researchers in a new study. The KZ ...

A better way to tell which species are vulnerable

Wildfires, floods, pollution, and overfishing are among the many disruptions that can change the balance of ecosystems, sometimes endangering the future of entire species. But evaluating these ecosystems to determine which ...
