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…
Monolithic integration of optically anisotropic GeSe-based films on GaAs by templated solid-phase epitaxy
Kira J. Martin, Autumn Y. Lee, Pranav Mahaadev +6
Layered IV-VI semiconductors such as GeSe exhibit strong in-plane optical anisotropy, making them promising candidates for polarization-sensitive photonic devices. However, realizi…
Photoinduced orbital polarization and Jahn-Teller effect in RNiO
Sangeeta Rajpurohit, Sheikh Rubaiat Ul Haque, Aaron M. Lindenberg +2
The orbital degree of freedom in rare-earth nickelates is typically inactive across the temperature-driven metal-insulator transition, where the system develops two inequivalent Ni…
Alkaline-Earth Rare-Earth Fluoride Nanoparticle Superlattices for Ultrafast, Radiation Stable Scintillators
Parivash Moradifar, Tim Brandt van Driel, Masashi Fukuhara +9
Radioluminescent nanostructures provide a pathway to the fabrication of next-generation scintillators with tunability in composition, size, and morphology, and spectral and tempora…
Quantifying and minimizing dissipation in a non-equilibrium phase transition
Yuejun Shen, Zhiqiao Jiang, Yunfan Huang +4
In a finite-time continuous phase transition, topological defects emerge as the system undergoes spontaneous symmetry breaking. The Kibble-Zurek mechanism predicts how the defect d…
Terahertz field-induced giant symmetry modulations in a van der Waals antiferromagnet
Sheikh Rubaiat Ul Haque, Martin J. Cross, Sangeeta Rajpurohit +19
Strong-field terahertz (THz) excitations enable dynamic control over electronic, lattice and symmetry degrees of freedom in quantum materials. Here, we uncover pronounced terahertz…
