    • Breaking the glass ceiling: Configurational entropy measurements in extremely supercooled liquids 

      Berthier, Ludovic; Charbonneau, Patrick; Coslovich, Daniele; Ninarello, Andrea; Ozawa, M; Yaida, Sho (2017-06-01)
      Liquids relax extremely slowly on approaching the glass state. One explanation is that an entropy crisis, due to the rarefaction of available states, makes it increasingly arduous to reach equilibrium in that regime. Validating ...
    • Bypassing sluggishness: SWAP algorithm and glassiness in high dimensions 

      Charbonneau, Patrick; Berthier, Ludovic; Kundu, Joyjit
      The recent implementation of a swap Monte Carlo algorithm (SWAP) for polydisperse mixtures fully bypasses computational sluggishness and closes the gap between experimental and simulation timescales in physical dimensions ...
    • Configurational entropy measurements in extremely supercooled liquids that break the glass ceiling. 

      Berthier, Ludovic; Charbonneau, Patrick; Coslovich, Daniele; Ninarello, Andrea; Ozawa, Misaki; Yaida, Sho (Proceedings of the National Academy of Sciences of the United States of America, 2017-10-10)
      Liquids relax extremely slowly on approaching the glass state. One explanation is that an entropy crisis, because of the rarefaction of available states, makes it increasingly arduous to reach equilibrium in that regime. ...
    • Efficient measurement of point-to-set correlations and overlap fluctuations in glass-forming liquids. 

      Berthier, Ludovic; Charbonneau, Patrick; Yaida, Sho (J Chem Phys, 2016-01-14)
      Cavity point-to-set correlations are real-space tools to detect the roughening of the free-energy landscape that accompanies the dynamical slowdown of glass-forming liquids. Measuring these correlations in model glass formers ...
    • Growing timescales and lengthscales characterizing vibrations of amorphous solids. 

      Berthier, Ludovic; Charbonneau, Patrick; Jin, Y; Parisi, G; Seoane, B; Zamponi, Francesco (Proc Natl Acad Sci U S A, 2016-07-26)
      Low-temperature properties of crystalline solids can be understood using harmonic perturbations around a perfect lattice, as in Debye's theory. Low-temperature properties of amorphous solids, however, strongly depart from ...
    • How to create equilibrium vapor-deposited glasses 

      Berthier, Ludovic; Charbonneau, Patrick; Flenner, E; Zamponi, Francesco (2017-08-23)
      Glass films created by vapor-depositing molecules onto a substrate can exhibit properties similar to those of ordinary glasses aged for thousands of years. It is believed that enhanced surface mobility is the mechanism that ...
    • Origin of Ultrastability in Vapor-Deposited Glasses. 

      Berthier, Ludovic; Charbonneau, Patrick; Flenner, Elijah; Zamponi, Francesco (Physical review letters, 2017-11)
      Glass films created by vapor-depositing molecules onto a substrate can exhibit properties similar to those of ordinary glasses aged for thousands of years. It is believed that enhanced surface mobility is the mechanism that ...
    • Point-to-set lengths, local structure, and glassiness. 

      Berthier, Ludovic; Charbonneau, Patrick; Tarjus, Gilles; Yaida, Sho (Phys Rev E, 2016-09)
      The growing sluggishness of glass-forming liquids is thought to be accompanied by growing structural order. The nature of such order, however, remains hotly debated. A decade ago, point-to-set (PTS) correlation lengths were ...
    • Zero-temperature glass transition in two dimensions 

      Charbonneau, Patrick; Berthier, Ludovic; Ninarello, Andrea; Ozawa, Misaki; Yaida, Sho
      The nature of the glass transition is theoretically understood in the mean-field limit of infinite spatial dimensions, but the problem remains totally open in physical dimensions. Nontrivial finite-dimensional fluctuations are ...
