Extreme anharmonicity and thermal contraction of one-dimensional wires

Published in Nano Letters, 2025

Using the stochastic self-consistent harmonic approximation together with first-principles and machine-learning potentials, we show how extreme anharmonicity governs the vibrational properties and the negative thermal expansion of one-dimensional atomic wires.
