Lattice and orbital fluctuations in TiPO4
Dirk Wulferding, Angela Möller, Kwang-Yong Choi +7
In the s = 1/2 antiferromagnetic spin chain material TiPO4 the formation of a spin gap takes place in a two step process with two characteristic temperatures, T*=111 K and TSP=74 K…
Enhanced quasiparticle dynamics of quantum well states: the giant Rashba system BiTeI and topological insulators
V. Gnezdilov, P. Lemmens, D. Wulferding +5
In the giant Rashba semiconductor BiTeI electronic surface scattering with Lorentzian linewidth is observed that shows a strong dependence on surface termination and surface potent…
Evidence for Dimer Crystal Melting in the Frustrated Spin-Ladder BiCu2PO6
K. -Y. Choi, J. W. Hwang, P. Lemmens +3
In the spin ladder compound BiCuPO there exists a decisive dynamics of spin excitations that we classify and characterize using inelastic light scattering. We observe low-e…
Interplay between lattice and spin states degree of freedom in the FeSe superconductor: dynamic spin state instabilities
Vladimir Gnezdilov, Yurii G. Pashkevich, Peter Lemmens +5
Polarized Raman-scattering spectra of superconducting, single-crystalline FeSe evidence pronounced phonon anomalies with temperature reduction. A large 6.5% hardening of the B_1g(F…
