Plateau transitions of quantum spin chain
Quantum mechanics tells us particles are waves at the same time. One may then naively expect that the quantum […]

Symmetries and square-root operation
Motivated by the relation between the Dirac/Schrodinger hamiltonians, the square root topological phase (SRTI) […]

Square root semimetals
We propose topological semimetals generated by the square-root operation for tight-binding models in two and t […]

Bulk-edge correspondence with generalized chiral symmetry
Dirac cones are generically tilted when realized in a realistic material. This gapless structure is effectivel […]
