Exact two-holon wave functions in the Kuramoto-Yokoyama model

open access: yes, 2006
We construct the explicit two-holon eigenstates of the SU(2) Kuramoto-Yokoyama model at the level of explicit wave functions. We derive the exact energies and obtain the individual holon momenta, which are quantized according to the half-Fermi statistics

Spin exchange in quantum rings and wires in the Wigner-crystal limit

open access: yes, 2005
We present a controlled method for computing the exchange coupling in strongly correlated one-dimensional electron systems. It is based on the asymptotically exact relation between the exchange constant and the pair-correlation function of spinless ...

Specificity of aequorin luminescence to calcium [PDF]

open access: yes
The presence of Pb(++), Co(++), Cu(++), and Cd(++), each of which possesses a certain luminescence-triggering activity of aequorin, potentially interferes with the specificity of the aequorin luminescence response to Ca(++).
