Experimental evidence of crystal symmetry protection for the topological nodal line semimetal state in ZrSiS
C. C. Gu, J. Hu, X. L. Chen +19
Tunable symmetry breaking plays a crucial role for the manipulation of topological phases of quantum matter. Here, through combined high-pressure magneto-transport measurements, Ra…
Giant electrocaloric effect at the antiferroelectric-to-ferroelectric phase boundary in PbZrTiO
A. V. Kimmel, O. T. Gindele, D. M. Duffy +1
Molecular dynamics simulations predict a giant electrocaloric effect at the ferroelectric-antiferroelectric phase boundary in PZT (PbTiO-PbZrO). These large-scale simulatio…
Exploiting symmetry-mismatch to control magnetism in a ferroelastic heterostructure
Er-Jia Guo, Ryan Desautels, Dongkyu Lee +11
In the bulk, LaCoO3 (LCO) is a paramagnet, yet in tensile strained thin films at low temperature ferromagnetism (FM) is observed, and its origin remains unresolved. Polarized neutr…
Comment on High-Pressure Behavior of Hydrogen and Deuterium at Low Temperatures
Alexander F. Goncharov, Yu. A. Freiman
X.-D. Liu et al. [Phys. Rev. Lett. 119, 065301 (2017)] report on the existence of a new unique solid phase of D2, which makes the high-pressure low-temperature behavior distinct fr…
