Is there a density-gradient expansion for the electronic exchange energy?
John P. Perdew, Timo Lebeda, Rohan Maniar +3
An old but recurring question in ground-state density functional theory, relevant to the construction of density functional approximations, is the existence of a second-order gradi…
Balanced and broadly-normed meta-generalized gradient approximation
Yanyong Wang, Chandra Shahi, John P. Perdew +1
Conventional semi-local density functional approximations for the exchange-correlation energy systematically underestimate fundamental band gaps. Advanced meta-generalized gradient…
Elusive Exciton Insulator States in 1T-HfTe2: Exciton softening, and Symmetry Breaking by Ab Initio Methods
Hong Tang, Niraj Pangeni, Daniel D. Rivera +1
Recent experiments have provided evidence for excitonic insulator (EI) states in 1T HfTe2. In this work, we investigate EI states in monolayer, bilayer, trilayer, and bulk 1T HfTe2…
Rotational Phonons Drive Low-Energy Kinks in Cuprate Superconductors
Yanyong Wang, Manuel Engel, Christopher Lane +9
Angle-resolved photoemission spectroscopy (ARPES) reveals ubiquitous quasiparticle ``kinks'' near 70 meV and 40 meV across cuprate superconductors, often accompanied by…
Exchange field induced symmetry breaking in quantum hexaborides
D. Rivera, Fernando P. Sabino, H. Raebiger +3
Symmetry breaking (SB) has proven to be a powerful approach for describing quantum materials: strong correlation, mass renormalization, and complex phase transitions are among the…
Unusual Electron-Phonon Interactions in Highly Anisotropic Two-Dimensional
Fei Wang, Qiaohui Zhou, Hong Tang +9
Electron-phonon interactions (EPIs) represent a fundamental cornerstone of condensed matter physics, commanding persistent attention due to their pivotal role in driving novel quan…
