## Title

- title: Emergent spin-1 Haldane gap and ferroelectricity in a frustrated spin-1/2
    ladder
  title_type: original
  lang: en

## Description

- description: We report experimental and theoretical evidence that Rb2Cu2Mo3O12 has
    a nonmagnetic tetramer ground state of a two-leg ladder comprising　antiferromagnetically
    coupled frustrated spin- 1/2 chains and exhibits a Haldane spin gap of emergent
    spin-1 pairs. Three spin excitations split from the spin-1 triplet by a Dzyaloshinskii-Moriya
    interaction are identified in inelastic neutron-scattering and electron spin resonance
    spectra. A tiny magnetic field generates ferroelectricity without closing the
    spin gap, indicating a unique class of ferroelectricity induced by a vector spin
    chirality order.
