Observation and Spectroscopy of a Two-Electron Wigner Molecule in an Ultra-Clean Carbon Nanotube
S. Pecker, F. Kuemmeth, A. Secchi +4
Coulomb interactions can have a decisive effect on the ground state of electronic systems. The simplest system in which interactions can play an interesting role is that of two ele…
Realization of Pristine and Locally-Tunable One-Dimensional Electron Systems in Carbon Nanotubes
Jonah Waissman, Maayan Honig, Sharon Pecker +3
Recent years have seen the development of several experimental systems capable of tuning local parameters of quantum Hamiltonians. Examples include ultracold atoms, trapped ions, s…
A Gate-tunable Polarized Phase of Two-Dimensional Electrons at the LaAlO3/SrTiO3 Interface
Arjun Joshua, J. Ruhman, S. Pecker +2
Controlling the coupling between localized spins and itinerant electrons can lead to exotic magnetic states. A novel system featuring local magnetic moments and extended 2D electro…
A Universal Critical Density Underlying the Physics of Electrons at the LaAlO3/SrTiO3 Interface
Arjun Joshua, S. Pecker, J. Ruhman +2
The two-dimensional electron system formed at the interface between the insulating oxides LaAlO3 and SrTiO3 exhibits ferromagnetism, superconductivity, and a wide range of unique m…
