Hidden phonon-assisted charge density wave transition in BaFe2Al9 revealed by ultrafast optical spectroscopy
Lei Wang, Mingwei Ma, Jiangxu Li +10
The interplay between electronic and lattice degrees of freedom is fundamental to charge density wave (CDW) formation, yet the microscopic origin often remains elusive. Here, we in…
Nitrogen-tailored quasiparticle energy gaps of polyynes
Kan Zhang, Jiling Li, Peitao Liu +2
Polyyne, a sp1-hybridized linear allotrope of carbon, has a tunable quasiparticle energy gap, which depends on the terminated chemical ending groups as well as the chain length. Pr…
Two-dimensional Obstructed Atomic Insulators with Fractional Corner Charge in MAZ Family
Lei Wang, Yi Jiang, Jiaxi Liu +6
According to topological quantum chemistry, a class of electronic materials have been called obstructed atomic insulators (OAIs), in which a portion of valence electrons necessaril…
Thermal transport and phase transitions of zirconia by on-the-fly machine-learned interatomic potentials
Carla Verdi, Ferenc Karsai, Peitao Liu +2
Machine-learned interatomic potentials enable realistic finite temperature calculations of complex materials properties with first-principles accuracy. It is not yet clear, however…
Optical and excitonic properties of transition metal oxide perovskites by the Bethe-Salpeter equation
Lorenzo Varrassi, Peitao Liu, Zeynep Ergönenc Yavas +3
We present a systematic investigation of the role and importance of excitonic effects on the optical properties of transitions metal oxide perovskites. A representative set of four…
Interplay between multipolar spin interactions, Jahn-Teller effect and electronic correlation in a insulator
Dario Fiore Mosca, Leonid V. Pourovskii, Beom Hyun Kim +5
In this work we study the complex entanglement between spin interactions, electron correlation and Janh-Teller structural instabilities in the 5d spin-orb…
