The transformation of digital computers from bulky machines to portable systems has been
enabled by new materials and advanced processing technologies that allow ultrahigh …

Quasiparticles with fractional charge and fractional statistics are key features of the fractional
quantum Hall effect. We discuss in detail the definitions of fractional charge and statistics …

The presence of “upstream” modes, moving against the direction of charge current flow in
the fractional quantum Hall (FQH) phases, is critical for the emergence of renormalized …

Fractional quantum anomalous hall effect (FQAHE), a transport effect with fractionally
quantized Hall plateau emerging under zero magnetic field, provides a radically new …

The first isolation of graphene opens the avenue for new platforms for physics, electronic
engineering, and materials sciences. Among several kinds of synthesis approaches …

The Halperin-Lee-Read Fermi sea of composite fermions at half-filled lowest Landau level is
the realization of a fascinating metallic phase that is a strongly correlated “non-Fermi liquid” …

The rise of moir\'{e} materials has led to experimental realizations of integer and fractional
Chern insulators in small or vanishing magnetic fields. At the same time, a set of minimal …

Interferometers probe the wave-nature and exchange statistics of indistinguishable particles—
for example, electrons in the chiral one-dimensional edge channels of the quantum Hall …

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 …

Electron interferometry with quantum Hall (QH) edge channels in semiconductor
heterostructures can probe and harness the exchange statistics of anyonic excitations …
