Multimode Objective Lens for Momentum Microscopy and XPEEM: Experiments
O. Tkach, S. Fragkos, D. Biswas +37
A new type of objective lens has recently been proposed for use in X-ray photoemission electron microscopes (XPEEMs) and momentum microscopes. Adding a ring electrode concentric wi…
Quench of the electronic order in a strongly-coupled charge-density-wave system by enhanced lattice fluctuations
Manuel Tuniz, Denny Puntel, Wibke Bronsch +5
Charge-density-wave (CDW) materials having a strong electron-phonon coupling provide a powerful platform for investigating the intricate interplay between lattice fluctuations and…
Measurements of the quantum geometric tensor in solids
Mingu Kang, Sunje Kim, Yuting Qian +15
Understanding the geometric properties of quantum states and their implications in fundamental physical phenomena is at the core of modern physics. The Quantum Geometric Tensor (QG…
Unveiling exciton formation: exploring the early stages in time, energy and momentum domain
Valentina Gosetti, Jorge Cervantes-Villanueva, Selene Mor +9
Resolving the early-stage dynamics of exciton formation following non-resonant photoexcitation in time, energy, and momentum is quite challenging due to their inherently fast times…
Van der Waals engineering of ultrafast carrier dynamics in magnetic heterostructures
Paulina Majchrzak, Yuntian Liu, Klara Volckaert +10
Heterostructures composed of the intrinsic magnetic topological insulator MnBiTe and its non-magnetic counterpart BiTe host distinct surface electronic band structu…
