Energy-twisted boundary condition and response in one-dimensional quantum many-body systems
R Nakai, T Guo, S Ryu - Physical Review B, 2022 - APS
Thermal transport in condensed matter systems is traditionally formulated as a response to a
background gravitational field. In this work, we seek a twisted-boundary-condition formalism …
