Interaction induced staggered spin-orbit order in two-dimensional electron gas
Tanmoy Das
We propose and formulate an interaction induced staggered spin-orbit order as a new emergent phase of two-dimensional Fermi gases. We show that when some form of inherent spin-spli…
Self-consistent spin-fluctuation spectrum and correlated electronic structure of actinides
Tanmoy Das, Jian-Xin Zhu, Matthias J. Graf
We present an overview of various theoretical methods with detailed emphasis on an intermediate Coulomb-U coupling model. This model is based on material-specific ab-initio band st…
Stability of Weyl metals under impurity scattering
Zhoushen Huang, Tanmoy Das, Alexander V. Balatsky +1
We investigate the effects of bulk impurities on the electronic spectrum of Weyl semimetals, a recently identified class of Dirac-type materials. Using a -matrix approach, we st…
Lindhard and RPA susceptibility computations in extended momentum space in electron doped cuprates
Yung Jui Wang, B. Barbiellini, Hsin Lin +6
We present an approximation for efficient calculation of the Lindhard susceptibility in a periodic system through the use of simple products of real space functions an…
Electron-like Fermi surface and in-plane anisotropy due to chain states in YBaCuO superconductors
Tanmoy Das
We present magneto-transport calculations for YBaCuO (YBCO) materials to show that the electron-like metallic chain state gives both the negative Hall effect and in…
Origin of pressure induced second superconducting dome in AyFe2-xSe2 [A=K, (Tl,Rb)]
Tanmoy Das, A. V. Balatsky
Recent observation of pressure induced second superconducting phase in AyFe2-xSe2 [A=K, (Tl,Rb)] calls for the models of superconductivity that are rich enough to allow for multipl…
