Mechanically concealed holes
Kanka Ghosh, Andreas M. Menzel
When a hole is introduced into an elastic material, it will usually act to reduce the overall mechanical stiffness. A general ambition is to investigate whether a stiff shell aroun…
Slip-dominated structural transitions
Kanka Ghosh, Oguz Umut Salman, Sylvain Queyreau +1
We use molecular dynamics to show that plastic slip is a crucial component of the transformation mechanism of a square-to-triangular structural transition. The latter is a stylized…
Significant four-phonon scattering and its heat transfer implications in crystalline GeSbTe
Kanka Ghosh, Andrzej Kusiak, Jean-Luc Battaglia
We systematically demonstrate the temperature-dependent thermal transport properties in crystalline GeSbTevia first-principles density functional theory-informed linear…
Phonon hydrodynamics in crystalline materials
Kanka Ghosh, Andrzej Kusiak, Jean-Luc Battaglia
Phonon hydrodynamics is an exotic phonon transport phenomenon that challenges the conventional understanding of diffusive phonon scattering in crystalline solids. It features a pec…
Effect of characteristic size on the collective phonon transport in crystalline GeTe
Kanka Ghosh, Andrzej Kusiak, Jean-Luc Battaglia
We study the effect of characteristic size variation on the phonon thermal transport in crystalline GeTe for a wide range of temperatures using the first-principles density-functio…
Phonon hydrodynamics in crystalline GeTe at low temperature
Kanka Ghosh, Andrzej Kusiak, Jean-Luc Battaglia
A first-principles density functional method along with the direct solution of linearized Boltzmann transport equations are employed to systematically analyze the low-temperature t…
Thermal conductivity of amorphous and crystalline GeTe thin film at high temperature: Experimental and theoretical study
Kanka Ghosh, Andrzej Kusiak, Pierre Noé +2
Thermal transport properties bear a pivotal role in influencing the performance of phase change memory (PCM) devices, in which the PCM operation involves fast and reversible phase…
Soft-wall induced structure and dynamics of partially confined supercritical fluids
Kanka Ghosh, C. V. Krishnamurthy
The interplay between the structure and dynamics of partially confined Lennard Jones (LJ) fluids, deep into the supercritical phase, is studied over a wide range of densities in th…
Molecular dynamics of partially confined Lennard-Jones gases: Velocity autocorrelation function, mean squared displacement, and collective excitations
Kanka Ghosh, C. V. Krishnamurthy
Particle motion and correlations in fluids within confined domains promise to provide challenges and opportunities for experimental and theoretical studies. We report molecular dyn…
Structural behavior of supercritical fluids under confinement
Kanka Ghosh, C. V. Krishnamurthy
The location of the Frenkel line (FL) of a Lennard-Jones fluid which demarcates two distinct physical states, liquidlike and gaslike within the supercritical regime, has been estab…
