Chirality enhances diffusion in disordered environments
Joshua Uhlig, Jan Wójcik, Ralf Metzler +1
Chirality, a systematic rotational bias in the motion of a particle, arises in a wide range of physical and biological systems, from charged colloids in magnetic fields to swimming…
The chiral random walk: A quantum-inspired framework for odd diffusion
Jan Wójcik, Erik Kalz
Chirality in active and passive fluids gives rise to odd transport properties, most notably the emergence of robust edge currents that defy standard dissipative dynamics. While the…
Revisiting quantum walk advantages: A mean hitting time perspective
Jan Wójcik
The mean squared displacement has been widely used as the primary metric for comparing quantum and classical random walks, with quantum walks showing quadratic scaling versus linea…
Quantum Walks in Weak Stochastic Gauge Fields
Jan Wójcik
The behaviour of random quantum walks is known to be diffusive. Here we study discrete time quantum walks in weak stochastic gauge fields. In the case of position and spin dependen…
