Thermodynamics of free and bound magnons in graphene
Andrew T. Pierce, Yonglong Xie, Seung Hwan Lee +6
Symmetry-broken electronic phases support neutral collective excitations. For example, monolayer graphene in the quantum Hall regime hosts a nearly ideal ferromagnetic phase at fil…
Electrical generation and detection of spin waves in a quantum Hall ferromagnet
Di. S. Wei, Toeno van der Sar, Seung Hwan Lee +4
Spin waves are collective excitations of magnetic systems. An attractive setting for studying long-lived spin-wave physics is the quantum Hall (QH) ferromagnet, which forms spontan…
Mach-Zehnder interferometry using spin- and valley-polarized quantum Hall edge states in graphene
Di S. Wei, Toeno van der Sar, Javier D. Sanchez-Yamagishi +5
Confined to a two-dimensional plane, electrons in a strong magnetic field travel along the edge in one-dimensional quantum Hall channels that are protected against backscattering.…
Inducing Superconducting Correlation in Quantum Hall Edge States
Gil-Ho Lee, Ko-Fan Huang, Dmitri K. Efetov +6
The quantum Hall (QH) effect supports a set of chiral edge states at the boundary of a 2-dimensional electron gas (2DEG) system. A superconductor (SC) contacting these states induc…
