Quantum Correlations Reverse Thermodynamic Arrow of Time

April 2, 2018

A recent experiment shows how quantum mechanics can make heat flow from a cold body to a hot one, an apparent (though not real) violation of the second law of thermodynamics.

The Quantum Thermodynamics Revolution

May 2, 2017

As physicists extend the 19th-century laws of thermodynamics to the quantum realm, they’re rewriting the relationships among energy, entropy and information.


A Debate Over the Physics of Time

July 19, 2016

According to our best theories of physics, the universe is a fixed block where time only appears to pass.


The Thermodynamic Theory of Ecology

September 3, 2014

Nature’s large-scale patterns emerge from incomplete surveys that borrow ideas from information theory.

The arrow of time.

Time’s Arrow Traced to Quantum Source

April 16, 2014

A new theory explains the seemingly irreversible arrow of time while yielding insights into entropy, quantum computers, black holes, and the past-future divide.
