Interdisciplinary Physics Statistical Mechanics

How the structural organization of a network evolves as it is observed on larger and larger scales remains an open question. Now, a general and systematic approach to answer this question may be in sight.

Biological Physics Statistical Mechanics

Molecular dynamics simulations show that thermal gradients – of order 10¹⁰ K over a meter - can polarize liquid water. The finding could have interesting implications for developing hyperthermal treatments that target cancer cells.
