Probing the quantum metric of 3D topological insulators
Giacomo Sala, Emanuele Longo, Maria Teresa Mercaldo +5
The surface states of 3D topological insulators possess geometric structures that imprint distinctive signatures on electronic transport. A prime example is the Berry curvature, wh…
The quantum metric of electrons with spin-momentum locking
Giacomo Sala, Maria Teresa Mercaldo, Klevis Domi +4
Quantum materials are characterized by electromagnetic responses intrinsically linked to the geometry and topology of electronic wavefunctions, encoded in the quantum metric and Be…
Photoengineering the Magnon Spectrum in an Insulating Antiferromagnet
V. Radovskaia, R. Andrei, J. R. Hortensius +9
Femtosecond optical pulses have opened a new frontier in ultrafast dynamics, enabling direct access to fundamental interactions in quantum materials. In antiferromagnets (AFMs), wh…
Curvature-Controlled Polarization in Adaptive Ferroelectric Membranes
Greta Segantini, Ludovica Tovaglieri, Chang Jae Roh +12
In this study, we explore the ferroelectric domain structure and mechanical properties of PbTiO-based membranes, which develops a well-ordered and crystallographic-oriented rip…
Imaging orbital Rashba induced charge transport anisotropy
Eylon Persky, Xi Wang, Giacomo Sala +8
Identifying orbital textures and their effects on the electronic properties of quantum materials is a critical element in developing orbitronic devices. However, orbital effects ar…
