Terahertz field–induced ferroelectricity in quantum paraelectric SrTiO3
TL;DR: In this paper, an ultrafast phase transition into a hidden ferroelectric phase can be dynamically induced in quantum paraelectric strontium titanate (SrTiO3) using terahertz electric field excitation.
Journal ArticleDOI
Terahertz-Field-Induced Ferroelectricity in Quantum Paraelectric SrTiO$_3$
TL;DR: In this paper, an ultrafast phase transition into a hidden ferroelectric phase can be dynamically induced in the quantum paraelectric SrTiO$_3$ using intense terahertz electric field excitation, and the induced lowering in crystal symmetry yields dramatic changes in the phonon excitation spectra.
Journal ArticleDOI

TL;DR: In this paper, the optical conductivity in high-quality crystals of the chiral topological semimetal CoSi, which hosts exotic quasiparticles known as multifold fermions, is reported.
Journal ArticleDOI
Automatic Prediction of Surface Phase Diagrams Using Ab Initio Grand Canonical Monte Carlo
TL;DR: In this article, the authors combine density functional theory and grand canonical Monte Carlo (GCMC) to automate the discovery of realistic surfaces and apply it to the problem of surface phase diagram analysis.
Journal ArticleDOI
Ab initio Simulation Explains the Enhancement of Catalytic Oxygen Evolution on CaMnO3
TL;DR: In this paper, the formation of Mn vacancies caused by the solubility of Mn enhances lattice oxygen activity, which then reduces the energy of the adsorbate *OOH and therefore loosens the lower overpotential limit predicted from the scaling relationship.
