Spatially dispersive photogalvanic effects as a probe of quantum geometric tensor
Yicong Chen, Bumseop Kim, Senin Ahammed Akkara Paramban +8
Berry curvature and quantum metric of Bloch states govern a wide range of phenomena, yet unified experimental access to both remains limited. Here we show that light spatial-disper…
Opto-twistronic Hall effect in a three-dimensional spiral lattice
Zhurun Ji, Yuzhou Zhao, Yicong Chen +7
Studies of moire systems have elucidated the exquisite effect of quantum geometry on the electronic bands and their properties, leading to the discovery of new correlated phases. H…
Harnessing excitons at the nanoscale -- photoelectrical platform for quantitative sensing and imaging
Zhurun Ji, Mark E. Barber, Ziyan Zhu +8
Excitons -- quasiparticles formed by the binding of an electron and a hole through electrostatic attraction -- hold promise in the fields of quantum light confinement and optoelect…
Capturing dynamical correlations using implicit neural representations
Sathya Chitturi, Zhurun Ji, Alexander Petsch +16
The observation and description of collective excitations in solids is a fundamental issue when seeking to understand the physics of a many-body system. Analysis of these excitatio…
Z_2 Photonic topological insulators in the visible wavelength range for robust nanoscale photonics
Wenjing Liu, Minsoo Hwang, Zhurun Ji +3
Topological photonics provides an ideal platform for demonstrating novel band topology concepts, which are also promising for robust waveguiding, communication and computation appl…
Circular photogalvanic effect in 2D van der Waals heterostructure
Abdullah Rasmita, Chongyun Jiang, Hui Ma +3
Utilizing spin or valley degree of freedom is one of the promising approaches to realize more energy-efficient information processing. In the 2D transition metal dichalcogenide, th…
Observation and active control of a collective polariton mode and polaritonic band gap in few-layer WS2 strongly coupled with plasmonic lattices
Wenjing Liu, Yuhui Wang, Biyuan Zheng +7
Two-dimensional semiconductors host excitons with very large oscillator strengths and binding energies due to significantly reduced carrier screening. Two-dimensional semiconductor…
Spatially dispersive circular photogalvanic effect in a Weyl semimetal
Zhurun Ji, Gerui Liu, Zachariah Addison +8
Weyl semimetals are gapless topological states of matter with broken inversion and/or time reversal symmetry, which can support unconventional responses to externally applied elect…
