The electron addition spectrum A+(k,omega) is obtained analytically for the one-dimensional (1D) supersymmetric t-J model with 1/r2 interaction. The result is obtained first for a small-sized systemâ€¦ (More)

The exact one-to-one mapping between (spinless) Jordan-Wigner lattice fermions and (spin-1/2) spinons is established for all eigenstates of the one-dimensional s = 1/2 XX model on a lattice with anâ€¦ (More)

Using a newly developed hybrid Monte Carlo algorithm for the nearest-neighbor (nn) t-J model, we show that antiholons identified in the supersymmetric inverse squared (IS) t-J model are clearlyâ€¦ (More)

The thermodynamic limit of the dynamical density and spin-density two-point correlation functions for the spin Calogero-Sutherland model are derived from Uglovâ€™s finite-size results. The resultantâ€¦ (More)

The dynamical structure factor S(q, Ï‰) of the SU(K) (K = 2, 3, 4) Haldane-Shastry model is derived exactly at zero temperature for arbitrary size of the system. The result is interpreted in terms ofâ€¦ (More)

Abstract. The dynamical spin structure factor S(Q, Ï‰) in the small momentum region is derived analytically for the one-dimensional supersymmetric t-J model with 1/r interaction. Strong spin-chargeâ€¦ (More)

Storage and retrieval of parametric down-conversion (PDC) photons are demonstrated with electromagnetically induced transparency (EIT). Extreme frequency filtering is performed for THz order ofâ€¦ (More)

A probe light in a squeezed vacuum state was injected into cold 87Rb atoms with an intense control light in a coherent state. A sub-MHz window was created due to electromagnetically inducedâ€¦ (More)
