Dual topology and edge-reconstruction in -Sn
Jan Skolimowski, Nguyen Minh Nguyen, Giuseppe Cuono +2
We formulate the tight-binding model for cubic -Sn based on the DFT calculations. In the model, we incorporate a variable bond angle, which allows us to simulate the effect of t…
Dirac edge states as signature of two-dimensional altermagnetic topological crystalline phase
Raghottam M. Sattigeri, Xujia Gong, Amar Fakhredine +2
Two-dimensional (2D) metallic altermagnets present exciting opportunities for both fundamental research and practical innovations. Their ability to enhance tunneling magnetoresista…
Coexistence of Rashba and Dirac dispersions on the surface of centrosymmetric topological insulator decorated with transition metals
Giuseppe Cuono, Rajibul Islam, Amar Fakhredine +1
The Dirac cone originates from the bulk topology, yet its primary contribution comes from the surface since spatially, the Dirac state emerges at the boundary between the trivial a…
Spin-orbit insulating phase in SnTe cubic nanowires: consequences on the topological surface states
Ghulam Hussain, Kinga Warda, Giuseppe Cuono +1
We investigate the electronic, structural and topological properties of the SnTe and PbTe cubic nanowires using ab-initio calculations. Using standard and linear-scale density func…
Unprotected edge modes in quantum spin Hall insulator candidate materials
Nguyen Minh Nguyen, Giuseppe Cuono, Rajibul Islam +3
The experiments in quantum spin Hall insulator candidate materials, such as HgTe/CdTe and InAs/GaSb heterostructures, indicate that in addition to the topologically protected helic…
