C2nD „n51 – 3... anions
Anion photoelectron spectra of the carbon monohydrides, C2nH 2 for n51 – 4 and C2nD 2 for n51 – 3, have been measured. The spectra were recorded at a wavelength of 266 nm ~4.657 eV! and yield electron affinities for each species. The spectra are vibrationally resolved, and some of the vibrational modes in the neutral C2nH~D! radicals are assigned. In addition, photoelectron angular distribution...
متن کاملConsequences of a possible adiabatic transition between n51/3 and n51 quantum Hall states in a narrow wire
We consider the possibility of creating an adiabatic transition through a narrow neck, or point contact, between two different quantized Hall states that have the same number of edge modes, such as n51 and n 5 1 3. We apply both the composite-fermion and Luttinger-liquid formalism to analyze the transition. We suggest that using such adiabatic junctions one could build a dc step-up transformer,...
متن کاملLow temperature EPR spectra of the mesoscopic cluster V15: the role of antisymmetric exchange.
The low temperature EPR spectra of the unique nanometer-scale molecular magnet V(15) are analyzed within the three-spin model preserving trigonal symmetry. The Hamiltonian includes isotropic and antisymmetric (AS) exchange interactions introduced by Dzyaloshinsky (Zh. Eksp. Teor. Fiz. 32, 1547 (1957) [Sov. Phys. JETP 5, 1259 (1957)]) and [Moria Phys. Rev. 120, 91 (1960)]. With the aid of pseudo...
متن کاملDecoherence window and electron-nuclear cross relaxation in the molecular magnet V15.
Rabi oscillations in the V(15) single molecule magnet embedded in the surfactant (CH(3))(2)[CH(3)(CH(2))(16)CH(2)](2)N(+) have been studied at different microwave powers. An intense damping peak is observed when the Rabi frequency Ω(R) falls in the vicinity of the Larmor frequency of protons ω(N). The experiments are interpreted by a model showing that the damping (or Rabi) time τ(R) is directl...
متن کاملVariational Monte Carlo calculation of the spin gap in the n51 quantum Hall liquid
A variational method of calculating the spin 1 excitation energies of the n51 quantum Hall liquid is presented in detail. We are able to include Landau-level mixing and finite-thickness effects. The many-body wave functions of the states near n51 filling are taken to be a product of a lowest-Landau-level Laughlin-type wave function and a Jastrow factor. A significant reduction in the calculated...
