Investigation into the inadequacy of cRPA in reproducing screening in strongly correlated systems
Qiang Han, B. Chakrabarti, K. Haule
The accuracy of the constrained random phase approximation(cRPA) method is examined in multi-orbital Hubbard models containing all possible on-site density-density interactions. Us…
Role of Entropy and Structural Parameters in the Spin State Transition of LaCoO
Bismayan Chakrabarti, Turan Birol, Kristjan Haule
The spin state transition in LaCoO has eluded description for decades despite concerted theoretical and experimental effort. In this study, we approach this problem using fully…
The Valence-Fluctuating Ground State of Plutonium
M. Janoschek, Pinaki Das, B. Chakrabarti +13
A central issue in material science is to obtain understanding of the electronic correlations that control complex materials. Such electronic correlations frequently arise due to t…
transition in cerium: magnetic form factor and dynamic magnetic susceptibility in dynamical mean-field theory
B. Chakrabarti, M. E. Pezzoli, G. Sordi +2
The nature of the elemental cerium phases, undergoing an isostructural volume collapse transition, cannot be understood using conventional solid state concepts. Using the combinati…
Analysis of the long-range random field quantum antiferromagnetic Ising model
Bikas K. Chakrabarti, Arnab Das, Jun-ichi Inoue
We introduce a solvable quantum antiferromagnetic model. The model, with Ising spins in a transverse field, has infinite range antiferromagnetic interactions with random fields on…
