Irreversibility and Dissipation by Juan Parrondo
By ZEEYA MERALI
Abstract:

We learn in undergraduate courses the intimate relationship between entropy and irreversibility: an irreversible process is characterized by an increase of entropy. In the last years and using concepts from information theory, we...

Electromechanics for thermodynamics at the...
By NATALIA ARES
FQXI's Natalia Ares describes how quantum physicists are seeking to better understand how thermodynamics operates at small scales. Here, fluctuations are significant and quantum behaviour arises. This may reveal possibilities for entirely novel...

2019: Year in Physics Review Part 2: Concluding our countdown of the biggest stories of the year in physics, as chosen by quantum physicist Ian Durham.
2019: Year in Physics Review Part 1 Beginning our countdown of the biggest stories of the year in physics, as chosen by quantum physicist Ian Durham.
An amped up version of the Schrodinger Cat Paradox spells trouble for all quantum interpretations -- according to its architect Renato Renner. He tells Zeeya and Brendan how the controversial thought experiment works, and why he thinks it is bad news for fans of Many Worlds and quantum parallel universes, QBism, Collapse models and (less so) for Bohmian interpretations of quantum mechanics. But not everyone agrees.
