Magnetization processes and spin dynamics across field-induced phase transitions in the quasi-two-dimensional quantum magnet Cu(OH)Br
Anneke Reinold, Dirk Wulferding, Laur Peedu +13
We present magnetic-field-dependent evolution of magnetization and spin dynamics in the quasi-two-dimensional spin- magnet , consisting of alternately c…
Observation of an emergent energy scale close to dimensional reduction in a quasi-two-dimensional quantum magnet
Anneke Reinold, Laur Peedu, Kirill Amelin +19
By appropriately perturbing a critical transverse-field Ising chain away from its critical point, the system can develop a finite correlation length with a characteristic purely ma…
Low-energy spin excitations in field-induced phases of the spin-ladder antiferromagnet BiCuPO
Patrick Pilch, Kirill Amelin, Gary Schmiedinghoff +13
We report on terahertz spectroscopic measurements of quantum spin dynamics on single crystals of a spin-1/2 frustrated spin-ladder antiferromagnet BiCuPO as a function of t…
THz spin-wave excitations in the transverse conical phase of BiFeO
B. Tóth, D. G. Farkas, K. Amelin +7
Although BiFeO is one of the most studied multiferroic materials, recent magnetization and neutron scattering studies have revealed a new magnetic phase in this compound - the…
Spin excitations in the magnetically ordered phases of MnScS
B. Tóth, K. Amelin, T. Rõõm +5
Recent neutron scattering experiments suggested that frustrated magnetic interactions give rise to antiferromagnetic spiral and fractional skyrmion lattice phases in MnScS.…
Terahertz Magneto-optical investigation of quadrupolar spin-lattice effects in magnetically frustrated Tb2Ti2O7
K. Amelin, Y. Alexanian, U. Nagel +9
The significance of spin-lattice coupling in the phase diagram of the quantum spin-icepyrochlore Tb2Ti2O7 has been a topic of debate for some time. Here, we focus on the aspect of…
Experimental Observation of Quantum Many-Body Excitations of Symmetry in the Ising Chain Ferromagnet CoNbO
Kirill Amelin, Johannes Engelmayer, Johan Viirok +4
Close to the quantum critical point of the transverse-field Ising spin-chain model, an exotic dynamic spectrum was predicted to emerge upon a perturbative longitudinal field. The d…
Observation of E8 Particles in an Ising Chain Antiferromagnet
Zhao Zhang, Kirill Amelin, Xiao Wang +9
Near the transverse-field induced quantum critical point of the Ising chain, an exotic dynamic spectrum consisting of exactly eight particles was predicted, which is uniquely descr…
