Adiabatic theorem in the thermodynamic limit: Systems with a gap in the bulk
Joscha Henheik, Stefan Teufel
We prove a generalised super-adiabatic theorem for extended fermionic systems assuming a spectral gap only in the bulk. More precisely, we assume that the infinite system has a uni…
Adiabatic theorem in the thermodynamic limit: Systems with a uniform gap
Joscha Henheik, Stefan Teufel
We show that recent results on adiabatic theory for interacting gapped many-body systems on finite lattices remain valid in the thermodynamic limit. More precisely, we prove a gene…
A new approach to transport coefficients in the quantum spin Hall effect
Giovanna Marcelli, Gianluca Panati, Stefan Teufel
We investigate some foundational issues in the quantum theory of spin transport, in the general case when the unperturbed Hamiltonian operator does not commute with the spin…
Justifying Kubo's formula for gapped systems at zero temperature: a brief review and some new results
Joscha Henheik, Stefan Teufel
We first review the problem of a rigorous justification of Kubo's formula for transport coefficients in gapped extended Hamiltonian quantum systems at zero temperature. In particul…
