Bootstrapping Bloch bands
Serguei Tchoumakov, Serge Florens
Bootstrap methods, initially developed for solving statistical and quantum field theories, have recently been shown to capture the discrete spectrum of quantum mechanical problems,…
Three-dimensional chiral Veselago lensing
Serguei Tchoumakov, Jérôme Cayssol, Adolfo G. Grushin
The effect by which light focuses upon entering a medium with a negative refractive index, known as Veselago lensing, may enable optical imaging below the diffraction limit. Simila…
Conservation of chirality at a junction between two Weyl semimetals
Serguei Tchoumakov, Bogusz Bujnowski, Jonathan Noky +3
In Weyl semimetals the location of linear band crossings, the Weyl cones, is not bound to any high symmetry point of the Brillouin zone, unlike the Dirac nodes in graphene. This fl…
