Observation of spin-momentum locked surface states in amorphous BiSe
Paul Corbae, Samuel Ciocys, Daniel Varjas +12
Crystalline symmetries have played a central role in the identification of topological materials. The use of symmetry indicators and band representations have enabled a classificat…
Hybrid kernel polynomial method
Muhammad Irfan, Sathish R. Kuppuswamy, Daniel Varjas +4
The kernel polynomial method allows to sample overall spectral properties of a quantum system, while sparse diagonalization provides accurate information about a few important stat…
Interplay between boundary conditions and Wilson's mass in Dirac-like Hamiltonians
A. L. Araújo, R. P. Maciel, R. G. F. Dornelas +2
Dirac-like Hamiltonians, linear in momentum , describe the low-energy physics of a large set of novel materials, including graphene, topological insulators, and Weyl fermions. W…
Topological phases without crystalline counterparts
Daniel Varjas, Alexander Lau, Kim Pöyhönen +3
Recent years saw the complete classification of topological band structures, revealing an abundance of topological crystalline insulators. Here we theoretically demonstrate the exi…
Computation of topological phase diagram of disordered PbSnTe using the kernel polynomial method
Daniel Varjas, Michel Fruchart, Anton R. Akhmerov +1
We present an algorithm to determine topological invariants of inhomogeneous systems, such as alloys, disordered crystals, or amorphous systems. Based on the kernel polynomial meth…
