Symmetry breaking and Wigner molecules in few-electron quantum dots
We discuss symmetry breaking in two-dimensional quantum dots resulting from strong interelectron repulsion relative to the zero-point kinetic energy associated with the confining potential. Such symmetry breaking leads to the emergence of crystalline arrangements of electrons in the dot. The so-called Wigner molecules form already at field-free conditions. The appearance of rotating Wigner mole...
متن کاملEquilibration of a one-dimensional Wigner crystal.
Equilibration of a one-dimensional system of interacting electrons requires processes that change the numbers of left- and right-moving particles. At low temperatures such processes are strongly suppressed, resulting in slow relaxation towards equilibrium. We study this phenomenon in the case of spinless electrons with strong long-range repulsion, when the electrons form a one-dimensional Wigne...
متن کاملThe One-Dimensional Wigner Crystal in Carbon Nanotubes
Electron-electron interactions strongly affect the behavior of low-dimensional systems. In one dimension (1D), arbitrarily weak interactions qualitatively alter the ground state producing a Luttinger liquid (LL)1 which has now been observed in a number of experimental systems2–6. Interactions are even more important at low carrier density, and in the limit when the long-ranged Coulomb potential...
متن کاملWigner-crystal states for the two-dimensional electron gas in a double-quantum-well system.
Using the Hartree-Fock approximation, we calculate the energy of different Wigner crystal states for the two-dimensional electron gas of a double quantum well system in a strong magnetic field. Our calculation takes interlayer hopping as well as an in-plane magnetic field into consideration. The ground state at small layer separations is a one-component triangular lattice Wigner state. As the l...
متن کاملAharonov-Bohm oscillations in a one-dimensional Wigner crystal ring.
We calculate the magnetic moment (‘persistent current’) in a strongly correlated electron system — a Wigner crystal — in a one-dimensional ballistic ring. The flux and temperature dependence of the persistent current in a perfect ring is shown to be essentially the same as for a system of non-interacting electrons. In contrast, by incorporating into the ring geometry a tunnel barrier that pins ...
