A pressure-induced topological phase with large Berry curvature in Pb1−xSnxTe
The picture of how a gap closes in a semiconductor has been radically transformed by topological concepts. Instead of the gap closing and immediately reopening, topological arguments predict that, in the absence of inversion symmetry, a metallic phase protected by Weyl nodes persists over a finite interval of the tuning parameter (for example, pressure P). The gap reappears when the Weyl nodes ...
متن کاملPressure-induced topological phase transitions in membranes.
Some highly unusual features of a lipid-water liquid crystal are revealed by high pressure x-ray diffraction, light scattering and dilatometric studies of the lamellar (bilayer Lα) to nonlamellar inverse hexagonal (HII) phase transition. (i) The size of the unit cell of the HII phase increases with increasing pressure. (ii) The transition volume, ∆Vbh, decreases and appears to vanish as the pre...

By using the second quantization approach, the transformation matrix is calculated and the Hamiltonian of system is diagonalized. With this Hamiltonian, the band structure and wave function can be calculated. By using calculated wave f...
متن کاملMechanical topological semimetals with massless quasiparticles and a finite Berry curvature
A topological quantum phase requires a finite momentum-space Berry curvature which, conventionally, can arise through breaking the inversion or the time-reversal symmetry so as to generate nontrivial, topologically invariant quantities associated with the underlying energy band structure (e.g., a finite Chern number). For conventional graphene or graphenelike two-dimensional (2D) systems with g...
