Spontaneous Spin Polarization in Quantum Wires
A. D. Klironomos, J. S. Meyer, K. A. Matveev
A number of recent experiments report spin polarization in quantum wires in the absence of magnetic fields. These observations are in apparent contradiction with the Lieb-Mattis th…

Exchange Coupling in a One-Dimensional Wigner Crystal
A. D. Klironomos, R. R. Ramazashvili, K. A. Matveev
We consider a long quantum wire at low electron densities. In this strong interaction regime a Wigner crystal may form, in which electrons comprise an antiferromagnetic Heisenberg…
