Viscous heat backflow and temperature resonances in extreme thermal conductors
Jan DragaÅ¡eviÄ, Bogdan Rajkov, Michele Simoncelli
We demonstrate that non-diffusive, fluid-like heat transport, such as heat backflowing from cooler to warmer regions, can be induced, controlled, and amplified in extreme thermal c…

Weighing the curvature invariants
Jan DragaÅ¡eviÄ, Ina Moslavac, Ivica SmoliÄ
We prove several inequalities between the curvature invariants, which impose constraints on curvature singularities. Some of the inequalities hold for a family of spacetimes which…

Tunnelling of a composite particle in presence of a magnetic field
Bernard Faulend, Jan DragaÅ¡eviÄ
We present a simple model of composite particle tunnelling through a rectangular potential barrier in presence of magnetic field. The exact numerical solution of the problem is pro…
