Nonresonant optomechanical control of structural phases

Jiaojian Shi, Yijing Huang, Christian Heide +24

Optical tweezers demonstrate how light can exert forces to trap, repel, and manipulate microscopic particles without absorption. Recent theory has suggested that such forces can ex…

Understanding and Designing Phase Change Materials: Insights from Atom Probe Tomography

Jan Köttgen, Jan Köttgen, Nils von den Driesch +2

Phase Change Materials (PCMs) can be rapidly and reversibly switched between their amorphous and crystalline state; a transition which is accompanied by a pronounced change of opto…

Divergent Coherent Phonon Responses Across the Metal-Insulator Crossover

Felix Hoff, Timo Veslin, Tim Bartsch +3

Ultrafast laser control of material properties hinges on understanding light-matter interactions. We use two experimentally accessible response functions, laser fluence induced pho…

Isothermal Annealing Effects on -Relaxations and Crystallization Behaviors in Amorphous GeTe

Arune Makareviciute, Qun Yang, Tomoki Fujita +12

A secondary -relaxation process is often the dominant source of atomic dynamics below in many glass forming systems. Recent studies reported the presence of

Tailoring hBN's Phonon Polaritons with the Plasmonic Phase-Change Material In3SbTe2

Lina Jäckering, Aaron Moos, Lukas Conrads +8

Polaritons in van-der-Waals materials (vdWM) promise high confinement and multiple tailoring options by optical structures, e.g., resonators, launching structures and lenses. These…
