Distributed optical fiber sensing using forward propagation of multiple modes

Kavli Affiliate: Alireza Marandi | First 5 Authors: Luis Costa, Zhongwen Zhan, Alireza Marandi, , | Summary: Fiber optic distributed sensors typically demand bidirectional propagation in optical fibers to localize each point of measurement. This imposes barriers to their deployment in long-haul, amplified telecommunication links and prevents massive range enhancement through in-line amplification, due to […]

Large-gap insulating dimer ground state in monolayer IrTe2

Kavli Affiliate: Michael F. Crommie | First 5 Authors: Jinwoong Hwang, Kyoo Kim, Canxun Zhang, Tiancong Zhu, Charlotte Herbig | Summary: Monolayers of two-dimensional van der Waals materials exhibit novel electronic phases distinct from their bulk due to the symmetry breaking and reduced screening in the absence of the interlayer coupling. In this work, we […]
