Nonlinear electron transport induced by polarized terahertz radiation is studied in two-dimensional tellurene at room temperature. A direct current, quadratic in the radiation's electric field, is observed. Contributions sensitive to radiation helici

Recent theoretical studies of carrier-carrier scattering in degenerate two-dimensional systems have revealed radically different relaxation times for odd and even angular harmonics of distribution function. This theoretical concept, dubbed as 'tomogr

We provide a sufficient criterion for the recurrence of spatial random graphs on the real line based on the scarceness of long-edges. In particular, this complements earlier recurrence results obtained by Gracar et al. (Electron. J. Probab. 27 (2022)

We provide a very elementary proof of a classical extremality result due to Sidorenko (Discrete Math.\ 131.1-3, 1994), which states that among all graphs $G$ on $k$ vertices, the $k-1$-edge star maximises the number of graph homomorphisms of $G$ into

We report on the observation and study of the magneto-ratchet effect in a graphene-based two-dimensional metamaterial formed by a graphite gate that is placed below a graphene monolayer and patterned with an array of triangular antidots. We demonstra

In this paper, we develop high-order splitting methods for linear port-Hamiltonian systems, focusing on preserving their intrinsic structure, particularly the dissipation inequality. Port-Hamiltonian systems are characterized by their ability to desc

We analyse the effect of a fat-tailed waiting time distribution in the voter model on the complete graph with $N$ vertices. Our main result is the existence of a limiting infinite voter model on the slowest updating sites. We further derive explicitl

Our studies of the cyclotron resonance (CR) photoresistance in GaAs-based two-dimensional electron systems (2DES) reveal an anomalously low sensitivity to the helicity of the incoming circularly polarized terahertz radiation. We find that this anomal

We report on the observation of a nonlinear intensity dependence of the terahertz radiation induced ratchet effects in bilayer graphene with asymmetric dual grating gate lateral lattices. These nonlinear ratchet currents are studied in structures of

We study some systems of interacting fields whose evolution is given by singular stochastic partial differential equations of mean field type. We provide a robust setting for their study leading to a well-posedness result and a propagation of chaos r
