Complete kinematic null for local kinetic dissipation in a sixfold-driven electron fluid
P. Shubham Parashar
We identify a complete kinematic null in a two-dimensional electron fluid driven by a sixfold boundary pattern. In the channel of , device symmetry excludes both…
Thermal and viscous contrast in quantum Hall scanning-probe images
P. Shubham Parashar
Quantum Hall scanning images are often read as maps of a local potential, temperature, or viscosity, whereas a probe records a finite-resolution functional of a transport operator.…
Diffusive and hydrodynamic magnetotransport around a density perturbation in a two-dimensional electron gas
P. S. Parashar, M. M. Fogler
We study current flow around a density inhomogeneity in a two-dimensional electron gas in the presence of a strong magnetic field. The inhomogeneity is parametrized by a power-law…
Imaging the diffusive-to-ballistic crossover of magnetotransport in graphene
Zachary J. Krebs, Wyatt A. Behn, Keenan J. Smith +6
Scanning tunneling potentiometry (STP) is used to probe the local, current-induced electrochemical potential of carriers in graphene near circular electrostatic barriers in an out-…
