“…Experimental Signatures.-To explore the experimental signatures of the newly discovered SABSs, we consider a normal metal/superconductor (NS) junction in a doped WSM and calculate the normalized tunneling conductance σ n (eV ) = σ S (eV )/σ N (eV ) using the tight binding model in Eq. (1) with an appropriate boundary condition [51,52]. Here σ S (eV ) is the conductance of the NS junction, and σ N (eV ) is that in the normal state.…”

It has been noted that certain surfaces of Weyl semimetals have bound states forming open Fermi arcs, which are never seen in typical metallic states. We show that the Fermi arcs enable them to support an even more exotic surface state with crossed flat bands in the superconducting state. We clarify the topological origin of the crossed flat bands and the relevant symmetry that stabilizes the cross point. We also discuss their possible experimental verification by tunneling spectroscopy.

“…However, our approach is different from the very beginning because we propose an ordering for kinetic term based on a specific argument for the matching conditions. This ordering is also used in [24] for studying connection rules for effective-mass wave functions across an abrupt heterojunction.…”

Neste trabalho investigamos as soluções da equação de Schrödinger de osciladores com massa dependente da posição utilizando o método algébrico de operadores escada e uma transformação canônica de ponto. Os resultados são ilustrados para um sistema onde m(x) ∝ x2. De posse das funções de onda, calculamos a informação de Fisher e a entropia de Shannon para a posição e momentum de uma partícula no estado fundamental deste sistema.
