Wire width and density dependence of the crossover in the peak of the static structure factor from in one-dimensional paramagnetic electron gases
Ankush Girdhar, Vinod Ashokan, Rajesh O. Sharma +2
We use the variational quantum Monte Carlo (VMC) method to study the wire width () and electron density () dependences of the ground-state properties of quasi-one-di…
Ground-state properties of electron-electron biwire systems
Rajesh O. Sharma, N. D. Drummond, Vinod Ashokan +2
The correlation between electrons in different quantum wires is expected to affect the electronic properties of quantum electron-electron biwire systems. Here, we use the variation…
Quantum Monte Carlo method for metal catalysis: case study of hydrogen production on Pt(111)
Rajesh O. Sharma, Tapio T Rantala, Philip E Hoggan
Over 90 % of all chemical manufacture uses a solid catalyst. Related work thus responds to major societal demand. This study is of water-gas shift on platinum for hydrogen producti…
Selective hydrogen production at platinum surfaces investigated by the Quantum Monte Carlo approach to chemical reactions
Rajesh O. Sharma, Tapio Rantala, Philip E Hoggan
The present letter describes an atomic scale investigation of a chemical reaction for selective hydrogen production. This clean fuel is a sustainable energy source. Because electro…
