Chiral voltage propagation in a self-calibrated topolectrical Chern circuit
Tobias Hofmann, Tobias Helbig, Ching Hua Lee +2
We propose an electric circuit array with topologically protected uni-directional voltage modes at its boundary. Instead of external bias fields or floquet engineering, we employ n…
Landau level quantization of Dirac electrons on the sphere
Martin Greiter, Ronny Thomale
Interactions in Landau levels can stabilize new phases of matter, such as fractionally quantized Hall states. Numerical studies of these systems mostly require compact manifolds li…
Method to identify parent Hamiltonians for trial states
Martin Greiter, Vera Schnells, Ronny Thomale
We describe a general method to identify exact, local parent Hamiltonians for trial states like quantum Hall or spin liquid states, which we have used extensively during the past d…
