Unfolding the complexity of quasi-particle physics in disordered materials
Sai Mu, Raina Olsen, B. Dutta +9
The concept of quasi-particles forms the theoretical basis of our microscopic understanding of emergent phenomena associated with quantum mechanical many-body interactions. However…
Temperature-dependent phonon spectra of magnetic random solid solutions
Yuji Ikeda, Fritz Körmann, Biswanath Dutta +4
A first-principles-based method for computing phonons of magnetic random solid solutions including thermal magnetic fluctuations is developed. The method takes fluctuations of forc…
Low temperature features in the heat capacity of unary metals and intermetallics for the example of bulk aluminum and AlSc
Ankit Gupta, Bengü Tas Kavakbasi, Biswanath Dutta +6
We explore the competition and coupling of vibrational and electronic contributions to the heat capacity of Al and AlSc at temperatures below 50 K combining experimental calori…
Ab initio explanation of disorder and off-stoichiometry in Fe-Mn-Al-C kappa carbides
P. Dey, R. Nazarov, B. Dutta +6
Carbides play a central role for the strength and ductility in many materials. Simulating the impact of these precipitates on the mechanical performance requires the knowledge abou…
Robust Bain distortion in the premartensite phase of platinum substituted Ni2MnGa magnetic shape memory alloy
Sanjay Singh, B. Dutta, S. W. DSouza +7
The premartensite phase of shape memory and magnetic shape memory alloys (MSMAs) is believed to be a precursor state of the martensite phase with preserved austenite phase symmetry…
A new first principles approach to calculate phonon spectra of disordered alloys
Oscar Grånäs, Biswanath Dutta, Subhradip Ghosh +1
The lattice dynamics in substitutional disordered alloys with constituents having large size differences is driven by strong disorder in masses, inter-atomic force constants and lo…
