Branched flows in active random walks and the formation of ant trail patterns
King Hang Mok, Ragnar Fleischmann
Branched flow governs the transition from ballistic to diffusive motion of waves and conservative particle flows in spatially correlated random or complex environments. It occurs i…
Husimi function for electrons moving in magnetic fields
George Datseris, Ragnar Fleischmann
Husimi functions allow one to obtain sensible and useful phase space probability distributions from quantumechanical wavefunctions or classical wave fields, linking them to (semi-)…
Branched Flow
Eric J Heller, Ragnar Fleischmann, Tobias Kramer
In many physical situations involving diverse length scales, waves or rays representing them travel through media characterized by spatially smooth, random, modest refactive index…
Phase space analysis of quantum transport in electronic nanodevices
George Datseris, Ragnar Fleischmann
Electronic transport in nanodevices is commonly studied theoretically and numerically within the Landauer-Büttiker formalism: a device is characterized by its scattering properties…
Estimating Lyapunov exponents in billiards
George Datseris, Lukas Hupe, Ragnar Fleischmann
Dynamical billiards are paradigmatic examples of chaotic Hamiltonian dynamical systems with widespread applications in physics. We study how well their Lyapunov exponent, character…
Robustness of ballistic transport in antidot superlattices
George Datseris, Theo Geisel, Ragnar Fleischmann
The magneto-resistance of antidot lattices shows pronounced peaks, which became a hallmark of ballistic electron transport. While most studies agree that they reflect the interplay…
