Computational quantum transport: a scattering approach perspective
Xavier Waintal, Michael Wimmer, Anton Akhmerov +5
This review is devoted to the different techniques that have been developed to compute the phase-coherent transport properties of quantum nanoelectronic systems connected to electr…
Pymablock: an algorithm and a package for quasi-degenerate perturbation theory
Isidora Araya Day, Sebastian Miles, Hugo K. Kerstens +2
A common technique in the study of complex quantum-mechanical systems is to reduce the number of degrees of freedom in the Hamiltonian by using quasi-degenerate perturbation theory…
Isotropic 3D topological phases with broken time reversal symmetry
Helene Spring, Anton R. Akhmerov, Daniel Varjas
Axial vectors, such as current or magnetization, are commonly used order parameters in time-reversal symmetry breaking systems. These vectors also break isotropy in three dimension…
Establishing Coherent Momentum-Space Electronic States in Locally Ordered Materials
Samuel T. Ciocys, Quentin Marsal, Paul Corbae +6
In our understanding of solids, the formation of highly spatially coherent electronic states, fundamental to command the quantum behavior of materials, relies on the existence of d…
Structural spillage: an efficient method to identify non-crystalline topological materials
Daniel Muñoz-Segovia, Paul Corbae, Dániel Varjas +3
While topological materials are not restricted to crystals, there is no efficient method to diagnose topology in non-crystalline solids such as amorphous materials. Here we introdu…
Generalizations of the Pfaffian to non-antisymmetric matrices
Daniel Varjas
We study two generalizations of the Pfaffian to non-antisymmetric matrices and derive their properties and relation to each other. The first approach is based on the Wigner normal-…
