Cairo lattice with time-reversal non-invariant vertex couplings

Marzieh Baradaran, Pavel Exner

We analyze the spectrum of a periodic quantum graph of the Cairo lattice form. The used vertex coupling violates the time reversal invariance and its high-energy behavior depends o…

Magnetic square lattice with vertex coupling of a preferred orientation

Marzieh Baradaran, Pavel Exner, Jiří Lipovský

We analyze a square lattice graph in a magnetic field assuming that the vertex coupling is of a particular type violating the time reversal invariance. Calculating the spectrum num…
