Giant nonlocality in nearly compensated two-dimensional semimetals
Giant nonlocality in nearly compensated two-dimensional semimetals
In compensated two-component systems in confined, two-dimensional geometries, nonlocal response may appear due to an external magnetic field. Within a phenomenological two-fluid framework, we demonstrate the evolution of charge flow profiles and the emergence of a giant nonlocal pattern dominating charge transport in a magnetic field. Applying our approach to …
