Coherent manipulation of the binary degrees of freedom is at the heart of modern quantum
technologies. Graphene offers two binary degrees: the electron spin and the valley. Efficient …

The Fermi surface of elemental bismuth consists of three small rotationally equivalent
electron pockets, offering a valley degree of freedom to charge carriers. A relatively small …

Fractional quantum Hall states (FQHSs) at even-denominator Landau level filling factors (ν)
are of prime interest as they are predicted to host exotic, topological states of matter. We …

We report low temperature magnetotransport measurements on a high mobility (μ= 325 000
cm 2/V s) two-dimensional electron system on a H-terminated Si (111) surface. We observe …

We theoretically investigate the orbital effects of an in-plane magnetic field on the spectrum
of a quantum dot embedded in a two-dimensional electron gas (2DEG). We derive an …

We measure the renormalized effective mass (m∗) of interacting two-dimensional electrons
confined to an AlAs quantum well while we control their distribution between two spin and …

The emerging field of valleytronics harnesses the valley degree of freedom of electrons, akin
to how electronic and spintronic devices utilize the charge and spin degrees of freedom of …

We measure the effective mass (m∗) of interacting two-dimensional electrons confined to a
4.5-nm-wide AlAs quantum well. The electrons in this well occupy a single out-of-plane …

In a number of widely studied materials, such as Si, AlAs, Bi, graphene, MoS 2, and many
transition metal dichalcogenide monolayers, electrons acquire an additional, spinlike …

We measure the effective mass (m*) of interacting two-dimensional electrons confined to an
AlAs quantum well while we change the conduction-band valley occupation and the spin …
