Pinned wigner crystal
Webb7 mars 2024 · The experimental results suggest a new method to map out a T vs ν phase diagram of the magnetic-field-induced WC precisely, and the screening efficiency of the pinned WC is very poor at very low T and improves at higher T once the WC melts.

Webb1 juli 2015 · These phases are ascribed to formation of a disorder-pinned Wigner crystal (WC) [17]. Our aim is to extend studies of this region by simultaneous analysis of the real and imaginary parts of the complex AC conductance. Comparing the results with the theory [19] we show that the behaviors of Re σ (ω) and Im σ (ω) are indeed characteristic for ... WebbWe study a model of pinned bilayer Wigner crystals WC and focus on the effects of interlayer coherence IC on pinning. We consider both a pseudospin ferromagnetic WC FMWC with IC and a pseudospin antiferromagnetic WC AFMWC without IC. Our central finding is that a FMWC can be pinned more strongly due to the presence of IC.
Webb19 dec. 2024 · Abstract We consider the driven dynamics of Wigner crystals interacting with random disorder. Using numerical simulations, we find a rich variety of transport phenomena as a function of charge density, drive, and pinning strength. For weak pinning, the system forms a defect-free crystal that depins elastically. Webb18 sep. 1997 · A microscopic model for analyzing the microwave absorption properties of a pinned, two-dimensional Wigner crystal in a strong perpendicular magnetic field is developed. The method focuses on excitations within the lowest Landau level, and corresponds to a quantum version of the harmonic approximation.
