Negative Differential Resistivity from Holography

Understand

Negative differential resistivity (NDR) in a (3+1)-dimensional quantum system of strongly correlated charge carriers is theoretically reproduced by using the AdS/CFT correspondence.

• Our system is microscopically defined, and the analysis does not rely on any phenomenological models of NDR mechanism.
• The interaction between the heat reservoir and the nonequilibrium charge carriers is also taken into account.
• The system realizes insulation due to the formation of the neutral bound states of the charge carriers at low temperatures.
