Extraordinary Lifetime Enhancement of Coherent Phonon-Amplitude Modes in the Excitonic Insulator Phase of Ta2Pd3Te5
Anjan Kumar N M, Shuhan Wang, Snehashish Chatterjee +9
The excitonic insulator (EI) is an electronic phase of condensed excitons. However, in many prototypical materials the presence of a concurrent structural transition complicates th…

Uniaxial-Stress-Induced Magnetic Transitions in the Triangular-Lattice Antiferromagnet PdCrO2
Nina Stilkerich, Tobias Ritschel, Hilary M. L. Noad +10
Uniaxial stress is a promising method to tune magnetic frustration, allowing its effects to be studied in a precise way. In this work, uniaxial stress is applied to the triangular-…

Uniaxial strain-driven ferroelastic domain control in LaAlO3
Matthias Roeper, Robin Buschbeck, Jakob Wetzel +15
Multiferroic domain walls in functional oxides exhibit properties distinct from the bulk and are increasingly exploited as active elements in nanoelectronic and photonic devices. D…
