Probing spin-charge separation in a Tomonaga-Luttinger liquid.
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) at low energies. However, the clear observation of this spin-charge separation is an ongoing challenge experimentally. We have fabricated an electrostatically gated 1D system in which we observe spin-charge separation ...
متن کاملSpin resonance in a Luttinger liquid with spin-orbit interaction
Spin-orbit interaction in quantum wires leads to a spin resonance at low temperatures, even in the absence of an external dc magnetic field. We study the effect of electron-electron interaction on the resonance. This interaction is strong in quantum wires. We show that the electron-electron interaction changes the shape of the resonance curve and produces an additional cusp at the plasmon frequ...
متن کاملSpin-Charge Separated Luttinger Liquid in Arbitrary Spatial Dimensions
A model with a singular forward scattering amplitude for particles with opposite spins in d spatial dimensions is proposed and solved by using the bosonization transformation. This interacting potential leads to the spincharge separation. Thermal properties at low temperature for this Luttinger liquid are discussed. Also, the explicit form of the single-electron Green function is found; it has ...
متن کاملSpin - dependent charge of quasiparticle clusters in
A state with 2 electons has a charge of 1/2. The states of 3 electrons have quasiparticle charge of 4/11 and 5/13; the one with 5 electrons have quasiparticle charges 4/13 and 6/17. The state with 7 electrons exhibits quasiparticle charges of 5/17 and 12/17. When spin is reversed, the charge of three particle state changes from 4/11 to 7/11. These predicted results agree with the recent experim...
متن کاملColloquium: The spin-incoherent Luttinger liquid
In contrast to the well-known Fermi-liquid theory of three dimensions, interacting one-dimensional and quasi-one-dimensional systems of fermions are described at low energy by an effective theory known as Luttinger liquid theory. This theory is expressed in terms of collective many-body excitations that show exotic behavior such as spin-charge separation. Luttinger liquid theory is commonly app...
