Nature of the many-body excitations in a quantum wire: theory and experiment
O. Tsyplyatyev, A. J. Schofield, Y. Jin +8
The natural excitations of an interacting one-dimensional system at low energy are hydrodynamic modes of Luttinger liquid, protected by the Lorentz invariance of the linear dispers…
Hierarchy of modes in an interacting system
O. Tsyplyatyev, A. J. Schofield, Y. Jin +7
Studying interacting fermions in 1D at high energy, we find a hierarchy in the spectral weights of the excitations theoretically and we observe evidence for second-level excitation…
Probing spin-charge separation in a Tomonaga-Luttinger liquid
Y. Jompol, C. J. B. Ford, J. P. Griffiths +6
In a one-dimensional (1D) system of interacting electrons, excitations of spin and charge travel at different speeds, according to the theory of a Tomonaga-Luttinger Liquid (TLL) a…
Possible evidence of a spontaneous spin-polarization in mesoscopic 2D electron systems
A. Ghosh, C. J. B. Ford, M. Pepper +2
We have experimentally studied the non-equilibrium transport in low-density clean 2D electron systems at mesoscopic length scales. At zero magnetic field (B), a double-peak structu…
