Boundary conditions and violations of bulk-edge correspondence in a hydrodynamic model
Gian Michele Graf, Alessandro Tarantola
Bulk-edge correspondence is a wide-ranging principle that applies to topological matter, as well as a precise result established in a large and growing number of cases. According t…
Galilei covariance of the theory of Thouless pumps
Tilman Esslinger, Gian Michele Graf, Filippo Santi
The Thouless theory of quantum pumps establishes the conditions for quantized particle transport per cycle, and determines its value. When describing the pump from a moving referen…
Infraparticle states in the massless Nelson model -- revisited
Vincent Beaud, Wojciech Dybalski, Gian Michele Graf
We provide a new construction of infraparticle states in the massless Nelson model. The approximating sequence of our infraparticle state does not involve any infrared cut-offs. It…
Topology in shallow-water waves: a violation of bulk-edge correspondence
Gian Michele Graf, Hansueli Jud, Clément Tauber
We study the two-dimensional rotating shallow-water model describing Earth's oceanic layers. It is formally analogue to a Schrödinger equation where the tools from topological insu…
Indirect Measurements of a Harmonic Oscillator
Martin Fraas, Gian Michele Graf, Lisa Hänggli
The measurement of a quantum system becomes itself a quantum-mechanical process once the apparatus is internalized. That shift of perspective may result in different physical predi…
The Bulk-Edge Correspondence for Disordered Chiral Chains
Gian Michele Graf, Jacob Shapiro
We study one-dimensional insulators obeying a chiral symmetry in the single-particle picture. The Fermi level is assumed to lie in a mobility gap. Topological indices are defined f…
