Experimental Observation of Quantum Many-Body Excitations of $E_{8}$ Symmetry in the Ising Chain Ferromagnet CoNb $_{2}$ O $_{6}$

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…

Ferroelectric order versus metallicity in Sr $_{1 - x}$ Ca $_{x}$ TiO $_{3 - δ}$ ( $x = 0.009$ )

Johannes Engelmayer, Xiao Lin, Fulya Koç +4

We report on a thermal-expansion study of the ferroelectric phase transition in insulating Sr $_{1 - x}$ Ca $_{x}$ TiO $_{3}$ ( $x = 0.009$ ) and its evolution upon increasing charge-carrier conc…

Charge transport in oxygen-deficient EuTiO $_{3}$ : the emerging picture of dilute metallicity in quantum-paraelectric perovskite oxides

Johannes Engelmayer, Xiao Lin, Christoph P. Grams +5

We report on a study of charge transport in EuTiO $_{3 - δ}$ single crystals with carrier density tuned across several orders of magnitude. Comparing this system with other quasi-cubi…

Quantum Criticality of an Ising-like Spin-1/2 Antiferromagnetic Chain in Transverse Magnetic Field

Zhe Wang, T. Lorenz, D. I. Gorbunov +11

We report on magnetization, sound velocity, and magnetocaloric-effect measurements of the Ising-like spin-1/2 antiferromagnetic chain system BaCo $_{2}$ V $_{2}$ O $_{8}$ as a function of tem…
