Transferable Interatomic Potentials for Aluminum from Ambient Conditions to Warm Dense Matter
Sandeep Kumar, Hossein Tahmasbi, Kushal Ramakrishna +5
We present a study on the transport and materials properties of aluminum spanning from ambient to warm dense matter conditions using a machine-learned interatomic potential (ML-IAP…
Impact of Electronic Correlations on High-Pressure Iron: Insights from Time-Dependent Density Functional Theory
Kushal Ramakrishna, Mani Lokamani, Andrew Baczewski +2
We present a comprehensive investigation of the electrical and thermal conductivity of iron under high pressures at ambient temperature, employing the real-time formulation of time…
Electrical Conductivity of Iron in Earth's Core from Microscopic Ohm's Law
Kushal Ramakrishna, Mani Lokamani, Andrew Baczewski +2
Understanding the electronic transport properties of iron under high temperatures and pressures is essential for constraining geophysical processes. The difficulty of reliably meas…
First-principles modeling of plasmons in aluminum under ambient and extreme conditions
Kushal Ramakrishna, Attila Cangi, Tobias Dornheim +2
The theoretical understanding of plasmon behavior is crucial for an accurate interpretation of inelastic scattering diagnostics in many experiments. We highlight the utility of lin…
Influence of finite temperature Exchange-Correlation effects in Hydrogen
Kushal Ramakrishna, Tobias Dornheim, Jan Vorberger
We use density functional molecular dynamics (DFT-MD) to study the effect of finite temperature exchange-correlation (xc) in Hydrogen. Using the Kohn-Sham approach, the xc energy o…
Ab-initio dielectric response function of diamond and other relevant high pressure phases of carbon
Kushal Ramakrishna, Jan Vorberger
The electronic structure and dielectric properties of the diamond, body centered cubic diamond (bc8), and hexagonal diamond (lonsdaleite) phases of carbon are computed using densit…
