Topological phase transitions without symmetry indication in naznsbbi

HIGHLIGHTS

• who: Jaemo Jeong from the DepartmentSungkyunkwan University have published the Article: Topological phase transitions without symmetry indication in NaZnSbBi, in the Journal: Scientific Reports Scientific Reports
• what: For completeness, the authors evaluate the other possible topological crystalline phases allowed in NaZnSb1-xBix. The authors focused on analyzing the first two topological phase transitions, which changed the mirror Chern_numbers without symmetry indications.

SUMMARY

The authors build a simplified effective model to demonstrate a mirror Chern_number change between the bands with the same symmetry representation, forbidding symmetry indication. There exist x-mirror Mx . . .
