Circular dichroism in resonant inelastic x-ray scattering from birefringence in CuO
Abhishek Nag, Gérard Sylvester Perren, Hiroki Ueda +6
Resonant inelastic x-ray scattering (RIXS) has become a prominent technique to study quasiparticle excitations. With advances in polarization analysis capabilities at different fac…
Non-equilibrium dynamics of spin-lattice coupling
Hiroki Ueda, Roman Mankowsky, Eugenio Paris +18
Interactions between the different degrees of freedom form the basis of many manifestations of intriguing physics in condensed matter. In this respect, quantifying the dynamics of…
Conical spin order with chiral quadrupole helix in CsCuCl3
Hiroki Ueda, Elizabeth Skoropata, Max Burian +5
Here we report a resonant x-ray diffraction (RXD) study at the Cu L3 edge on the multi-chiral system CsCuCl3, exhibiting helical magnetic order in a chiral crystal structure. RXD i…
Field-induced ordering in a random-bond quantum spin ladder compound with weak anisotropy
G. S. Perren, W. E. A. Lorenz, E. Ressouche +1
The field induced quantum phase transitions in the disorder-free and disordered samples of the spin ladder material (CH_3)_2CHNH_3Cu(Cl_{1-x}Br_x)_3 are studied using magnetic calo…
Quantum criticality in a three dimensional spin system at zero field and pressure
K. Yu. Povarov, A. Mannig, G. Perren +4
We report spontaneous appearance of antiferromagnetic order in a model gapped quantum paramagnet Ni(ClBr)4SC(NH) induced by a change in bromine conce…
High pressure Raman study of the quantum magnet (CHN)CuCl
Simon Bettler, Gediminas Simutis, Gérard Perren +3
Magnetic and lattice excitations in the quantum antiferromagnet (CHN)CuCl (PHCC) are studied across two pressure-induced phase transition at $P_c=4.3~\mathrm…
