Note on linear response for interacting Hall insulators
Sven Bachmann, Alex Bols, Wojciech De Roeck +1
We relate explicitly the adiabatic curvature -- in flux space -- of an interacting Hall insulator with nondegenerate ground state to various linear response coefficients, in partic…
A many-body index for quantum charge transport
Sven Bachmann, Alex Bols, Wojciech De Roeck +1
We propose an index for pairs of a unitary map and a clustering state on many-body quantum systems. We require the map to conserve an integer-valued charge and to leave the state,…
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 adiabatic theorem in a quantum many-body setting
Sven Bachmann, Wojciech De Roeck, Martin Fraas
In these lecture notes, we review the adiabatic theorem in quantum mechanics, focusing on a recent extension to many-body systems. The role of locality is emphasized and the relati…
