Wigner molecules in quantum dots: A quantum Monte Carlo study
Semiconductor quantum dots ~QD’s! are small devices containing a tunable number of electrons in an external confinement potential. The significant progress in the fabrication of these devices during the last few years has stimulated an increasing interest in investigating the properties of such systems. From the theoretical point of view, QD’s are ideal many-electron objects for the study of fu...
متن کاملWigner molecules in polygonal quantum dots: A density-functional study
We investigate the properties of many-electron systems in two-dimensional polygonal ~triangle, square, pentagon, hexagon! potential wells by using the density-functional theory. The development of the ground-state electronic structure as a function of the dot size is of particular interest. First, we show that in the case of two electrons, the Wigner molecule formation agrees with previous exac...
متن کاملDiffusion quantum Monte Carlo study of three-dimensional Wigner crystals
We report diffusion quantum Monte Carlo calculations of three-dimensional Wigner crystals in the density range rs5100–150. We have tested different types of orbital for use in the approximate wave functions but none improve upon the simple Gaussian form. The Gaussian exponents are optimized by directly minimizing the diffusion quantum Monte Carlo energy. We have carefully investigated and sough...
متن کاملExact diagonalization and Quantum Monte Carlo studies of quantum dots
We report exact diagonalization and diffusion quantum Monte Carlo calculations of quantum dots (QDs) in which energetics due to electron-electron interactions, magnetic field, and geometrical factors compete and induce interesting ground state configurations. The geometrical effects are generated by different confining potentials such as parabolic shaped, ring shaped, and disordered potentials....
متن کاملSymmetry 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...
