Rapidly rotating boson molecules with long- or short-range repulsion: An exact diagonalization study
The Hamiltonian for a small number N 11 of bosons in a rapidly rotating harmonic trap, interacting via a short range contact potential or a long range Coulomb interaction, is studied via an exact diagonalization in the lowest Landau level. Our analysis shows that, for both low and high fractional fillings, the bosons localize and form rotating boson molecules RBMs consisting of concentric polyg...
متن کاملColloidal Systems with both a Short-Range Attraction and a Long-Range Repulsion
Even though the Derjaguin-Landau-Verwey-Overbeek theory has been used to describe the interactions between charged colloidal particles for over half a century, research on systems with a weak short-range attraction and long-range repulsion (SALR) has begun receiving the intensive attention from the colloidal community only very recently. Systems with a SALR interaction include micrometer sized ...
متن کاملQuantum Critical Behavior of the Infinite-range Transverse Ising Spin Glass : An Exact Numerical Diagonalization Study
We report exact numerical diagonalization results of the infinite-range Ising spin glass in a transverse field Γ at zero temperature. Eigenvalues and eigenvectors are determined for various strengths of Γ and for system sizes N ≤ 16. We obtain the moments of the distribution of the spin-glass order parameter, the spin-glass susceptibility and the mass gap at different values of Γ. The disorder ...
متن کاملAn exact-diagonalization study of rare events in disordered conductors
We determine the statistical properties of wave functions in disordered quantum systems by exact diagonalization of one-, twoand quasi-one dimensional tight-binding Hamiltonians. In the quasi-one dimensional case we find that the tails of the distribution of wave-function amplitudes are described by the non-linear σ-model. In two dimensions, the tails of the distribution function are consistent...
متن کاملRandom walks with long-range self-repulsion on proper time
We introduce a model of self-repelling random walks where the short-range interaction between two elements of the chain decreases as a power of the difference in proper time. Analytic results on the exponent ν are obtained. They are in good agreement with Monte Carlo simulations in two dimensions. A numerical study of the scaling functions and of the efficiency of the algorithm is also presented.
