A variational approach for many-body systems at finite temperature
Tao Shi, Eugene Demler, J. Ignacio Cirac
We introduce a non-linear differential flow equation for density matrices that provides a monotonic decrease of the free energy and reaches a fixed point at the Gibbs thermal state…

Long-Distance Transfer and Routing of Static Magnetic Fields
Carles Navau, Jordi Prat-Camps, Oriol Romero-Isart +2
We show how the static magnetic field of a finite source can be transferred and routed to arbitrary long distances. This is achieved by using transformation optics, which results i…
