Magnetic skyrmions are topologically stable nanoscale particlelike objects that were
discovered in 2009. Since that time, intense research interest in the field has led to the …

Flat-band systems have attracted considerable interest in different branches of physics in the
past decades, providing a flexible platform for studying fundamental phenomena associated …

The quantum anomalous Hall (QAH) effect—a macroscopic manifestation of chiral band
topology at zero magnetic field—has been experimentally realized only by the magnetic …

Bernal bilayer graphene (BLG) offers a highly flexible platform for tuning the band structure,
featuring two distinct regimes. One is a tunable band gap induced by large displacement …

We report fabrication of graphene devices in a Corbino geometry consisting of concentric
circular electrodes with no physical edge connecting the inner and outer electrodes. High …

Topological properties of lattices are typically revealed in momentum space using concepts
such as the Chern number. Here, we study unconventional loop states, namely, the …

Low-frequency 1/f γ noise is ubiquitous, even in high-end electronic devices. Recently, it
was found that adsorbed O2 molecules provide the dominant contribution to flux noise in …

In this paper, a fractional-order higher-dimensional multicavity chaotic map is investigated in
the Caputo discrete delta's sense. The numerical formula of discrete fractional-order chaotic …

We have measured magnetoresistance of suspended graphene in the Corbino geometry at
magnetic fields up to B= 0.15 T, ie, in a regime uninfluenced by Shubnikov–de Haas …

Transport measurement of electron optics in monolayer graphene pn junction devices has
been traditionally studied with negative refraction and chiral transmission experiments in …
