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…
