Glass-like thermal conductivity and narrow insulating gap of EuTiO
Alexandre Jaoui, Shan Jiang, Xiaokang Li +8
Crystals and glasses differ by the amplitude and the temperature dependence of their thermal conductivity. However, there are crystals known to display glass-like thermal conductiv…
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…
Ferroelectric order versus metallicity in SrCaTiO ()
Johannes Engelmayer, Xiao Lin, Fulya Koç +4
We report on a thermal-expansion study of the ferroelectric phase transition in insulating SrCaTiO () and its evolution upon increasing charge-carrier conc…
Charge transport in oxygen-deficient EuTiO: 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 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 BaCoVO as a function of tem…
A ferroelectric quantum phase transition inside the superconducting dome of SrCaTiO
Carl Willem Rischau, Xiao Lin, Christoph P. Grams +8
SrTiO, a quantum paraelectric, becomes a metal with a superconducting instability after removal of an extremely small number of oxygen atoms. It turns into a ferroelectric up…
