    Direct observation of ultrafast hydrogen bond strengthening in liquid water

    Water is one of the most important, yet least understood, liquids in nature. Many anomalous properties of liquid water originate from its well-connected hydrogen bond network1, including unusually efficient vibra...

    SixGe1-x alloy as efficient phonon barrier in Ge/Si superlattices for thermoelectric applications

    By means of atomistic simulations we study how thermal transport is affected by several chemical and morphological parameters in Ge/Si superlattices. We predict thermal conductivity as a function of the alloy...

    Calculating thermal conductivity in a transient conduction regime: theory and implementation

    We present a molecular dynamics method addressed to the calculation of the lattice thermal conductivity during the transient regime of approach to equilibrium from an initial condition of nonuniform temperatu...
