Lifshitz Transition in Correlated Topological Semimetals

Advanced Science, EarlyView.
Theoretical calculations reveal that in YPtBi and GdPtBi, strong electronic correlations shift topological Dirac nodes away from the Fermi level by forming large hole pockets. This effect is sensitive to temperature and arises from interactions among 4d or 4f electrons, offering insights into Fermi surface engineering in quantum materials.

Synergistic Interplay of Acceptor and Isovalent Co‐Doping on BaZrO3‐Based Proton Conducting Oxides: A First‐Principles Study

Advanced Science, EarlyView.
Acceptor and isovalent co‐doping effects on hydration in BaZrO3 proton conductors are systematically investigated using first‐principles calculations. Acceptors enhance hydration by modulating oxygen vacancy formation, whereas isovalent dopants enhance hydration by stabilizing protons via increased A‐site cation–proton distances.

The $\gamma$-$\alpha$ iso-structural Transition in Cerium, a Critical Element

, 2013
Below the critical temperature $T_c\simeq 600 K$, an iso-structural transition, named $\gamma$-$\alpha$ transition,can be induced in Cerium by applying pressure. This transition is first-order, and is accompanied by a sizable volume collapse.
