Field-induced soft-mode quantum phase transition in La $_{1.855}$ Sr $_{0.145}$ CuO $_{4}$

J. Chang, N. B. Christensen, Ch. Niedermayer +13

Inelastic neutron-scattering experiments on the high-temperature superconductor La $_{1.855}$ Sr $_{0.145}$ CuO $_{4}$ reveal a magnetic excitation gap $Δ$ that decreases continuously u…

Direct Observation of Magnon Fractionalization in the Quantum Spin Ladder

B. Thielemann, Ch. Rüegg, H. M. Rønnow +12

We measure by inelastic neutron scattering the spin excitation spectra as a function of applied magnetic field in the quantum spin-ladder material (C5H12N)2CuBr4. Discrete magnon m…

Field-Controlled Magnetic Order in the Quantum Spin-Ladder System (Hpip)2CuBr4

B. Thielemann, Ch. Rüegg, K. Kiefer +18

Neutron diffraction is used to investigate the field-induced, antiferromagnetically ordered state in the two-leg spin-ladder material (Hpip)2CuBr4. This "classical" phase, a conseq…
