Entropic evidence for a Pomeranchuk effect in magic angle graphene
Asaf Rozen, Jeong Min Park, Uri Zondiner +9
In the 1950's, Pomeranchuk predicted that, counterintuitively, liquid 3He may solidify upon heating, due to a high excess spin entropy in the solid phase. Here, using both local an…
Cascade of Phase Transitions and Dirac Revivals in Magic Angle Graphene
Uri Zondiner, Asaf Rozen, Daniel Rodan-Legrain +10
Twisted bilayer graphene near the magic angle exhibits remarkably rich electron correlation physics, displaying insulating, magnetic, and superconducting phases. Here, using measur…
Visualizing Poiseuille flow of hydrodynamic electrons
Joseph A. Sulpizio, Lior Ella, Asaf Rozen +12
Hydrodynamics is a general description for the flow of a fluid, and is expected to hold even for fundamental particles such as electrons when inter-particle interactions dominate.…
Ballistic and hydrodynamic magnetotransport in narrow channels
Tobias Holder, Raquel Queiroz, Thomas Scaffidi +6
An increasing number of low carrier density materials exhibit a surprisingly large transport mean free path due to inefficient momentum relaxation. Consequently, charge transport i…
Simultaneous imaging of voltage and current density of flowing electrons in two dimensions
Lior Ella, Assaf Rozen, John Birkbeck +8
Electron transport in nanoscale devices can often result in nontrivial spatial patterns of voltage and current that reflect a variety of physical phenomena, particularly in nonloca…
