      abstract     = {Ba3NbFe3Si2O14 (langasite) is structurally and magnetically
                      single-domain chiral with the magnetic helicity induced
                      through competing symmetric exchange interactions. Using
                      neutron scattering, we show that the spin waves in
                      antiferromagnetic langasite display directional anisotropy.
                      On applying a time-reversal symmetry breaking magnetic field
                      along the c axis, the spin-wave energies differ when the
                      sign is reversed for either the momentum transfer ±→Q or
                      applied magnetic field ±μ0H. When the field is applied
                      within the crystallographic ab plane, the spin-wave
                      dispersion is directionally isotropic and symmetric in
                      ±μ0H. However, a directional anisotropy is observed in the
                      spin-wave intensity. We discuss this directional anisotropy
                      in the dispersion in langasite in terms of a field-induced
                      precession of the dynamic unit cell staggered magnetization
                      resulting from a broken twofold symmetry. Directional
                      anisotropy, often referred to as nonreciprocal responses,
                      can occur in antiferromagnetic phases in the absence of the
                      Dzyaloshinskii-Moriya interaction or other effects resulting
                      from spin-orbit coupling.},
