Photoinduced phase transitions have been intensively studied owing to their promising potential for next-generation devices. Here, the authors develop a novel analysis method: the so-called frequency-domain ARPES (FDARPES). They extend a well established measurement method of time-domain ARPES to detect how electrons are interacting with phonons during the photoinduced insulator-to-metal transition for TaNiSe. They successfully unravel the underlying nature of the photoinduced phase transition. This method has general applicability to other photoinduced phase transitions, including photoinduced magnetism or superconductivity.

The accurate description of phonons in a solid is one of the central research topics in the field of condensed matter physics and materials science. Here, the authors report a successful application of the quantum Monte Carlo (QMC) framework to a phonon dispersion calculation. The full phonon dispersion of diamond has been successfully calculated at the variational Monte Carlo level, based on the frozen-phonon technique. The QMC calculations were performed by the TurboRVB software package.

Realization of a tunable surface Dirac gap in Sb-doped

Intrinsic magnetic topological insulators, exemplified by MnBiTe, receive considerable research interest, due to the potential quantum anomalous Hall state and axion insulator phase at higher temperatures. Opening up an energy gap at the topological surface state is crucial for the realization of these effects. Here, the authors utilize systematic ARPES data to show that a gapped Dirac cone can be realized in Sb-doped MnBiTe. This gap remains immune regardless of the magnetic phase of the bulk system, while it increases monotonically with the density of Sb dopants.
