The 2020 Atlantic hurricane season was a record-smasher – and it's raising more concerns about climate change

It was clear before the 2020 Atlantic hurricane season started that it was going to be busy. Six months later, we're looking back at a trail of broken records, and the storms may still not be over even with the season's official ...

Minimal waste production is a fundamental law for animal locomotion

Is there a unifying principle underpinning animal locomotion in its rich diversity? A thermodynamic analysis performed by a Skoltech professor and his French collaborators at Université Paris Diderot, Université Paris Saclay, ...

New physical picture leads to a precise finite-size scaling of (3+1)-dimensional O(n) critical system

Since the establishment of the renormalization group theory, it has been known that systems of critical phenomena typically possess an upper critical dimension dc (dc=4 for the O(n) model), such that in spatial dimensions ...

Minimal-interface structures constrained in polycrystalline copper with extremely fine grains

Metals with nanoscale crystal grains are super-strong although they do not retain their structure at higher temperatures. As a result, it is challenging to explore their high strength during materials applications. In a new ...

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 ...

0.5°C matters: Seasonal contrast of rainfall becomes intense in warming target of the Paris Agreement

The Paris Agreement in 2015 proposed a target to limit global warming to less than 2 degrees C and pursue efforts to limit warming to less than 1.5 degrees C. Since then, great efforts have been devoted to exploring the impacts ...

Research team discovers uniquely quantum effect in erasing information

Researchers from Trinity have discovered a uniquely quantum effect in erasing information that may have significant implications for the design of quantum computing chips. Their surprising discovery brings back to life the ...

Quantum heat engine behaviour observed in a qubit

Although many of today's accepted theories of classical thermodynamics predate even the industrial revolution they helped to propel, many open questions remain around how these ideas translate to the level of single quantum ...

A protocol to minimize the thermodynamic cost of erasing a single bit over a given amount of time

Stochastic thermodynamics theory is a framework that delineates the amount of heat, dynamics and entropy in small (i.e., mesoscopic) systems that are far from a state of thermodynamic equilibrium. In recent years, scientists ...
