Yb3+ speciation and energy-transfer dynamics in quantum-cutting Yb3+-doped CsPbCl3 perovskite nanocrystals and single crystals
Joo Yeon D. Roh, Matthew D. Smith, Matthew J. Crane +4
Yb3+-doped inorganic metal-halide perovskites (Yb3+:CsPbX3, X = Cl, Br) have recently been discovered to display highly efficient quantum cutting, in which the energy from individu…
Crystal-electric-field excitations in a quantum-spin-liquid candidate NaErS
Shang Gao, Fan Xiao, Kazuya Kamazawa +5
The delafossite family of compounds with a triangular lattice of rare earth ions has been recently proposed as a candidate host for quantum spin liquid (QSL) states. To realize QSL…
Observation of two types of anyons in the Kitaev honeycomb magnet
N. Janša, A. Zorko, M. Gomilšek +6
Quantum spin liquid is a disordered magnetic state with fractional spin excitations. Its clearest example is found in an exactly solved Kitaev honeycomb model where a spin flip fra…
Plasmon enhanced upconversion luminescence near gold nanoparticles - Simulation and analysis of the interactions
Stefan Fischer, Florian Hallermann, Toni Eichelkraut +6
We investigate plasmon resonances in gold nanoparticles to enhance the quantum yield of upconverting materials. For this purpose, we use a rate equation model that describes the up…
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…
