Description
Quantum simulators are experimentally available materials, which satisfy well-defined quantum Hamiltonians and allow the quantitative prediction of spectacular many-body effects. An example of such materials are ideal spin ladders. So far, only one strong-leg spin ladder was studied. We recently managed, thanks to a breakthrough, to grow a second strong-leg spin ladder in large crystals, and deuterate them – making a study with neutron spectroscopy achievable. Here, we present our neutron spectroscopy measurements where both time of flight and multiplexing instruments were used. We determined the excitation spectrum from which the dispersion and Hamiltonian parameters were extracted. Finally, we will discuss future work to tune this material using uniaxial pressure.
