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…
Nonresonant Raman control of ferroelectric polarization
Jiaojian Shi, Christian Heide, Haowei Xu +15
Important advances have recently been made in the search for materials with complex multi-phase landscapes that host photoinduced metastable collective states with exotic functiona…
Prediction of Ambient-Pressure High-Temperature Superconductivity in Doped Transition-Metal Hydrides
Haowei Xu, Olivia Schneble, Rafael Jaramillo +2
The search for conventional superconductors with high transition temperatures () has largely focused on intrinsically metallic compounds. In this work, we explore the potentia…
Ultrafast switchable polar and magnetic orders by nonlinear light-matter interaction
Haoyu Wei, Daniel Kaplan, Haowei Xu +1
An outstanding challenge in materials science and physics is the harnessing of light for switching charge order in e.g., ferroelectrics. Here we propose a mechanism through which e…
Strong Long-Wave Infrared Optical Response in a Topological Semiconductor with a Mexican Hat Band Structure
Mark J. Polking, Haowei Xu, Raman Sankar +2
Light sources and photodetectors operating in the far- to mid-infrared (FIR/MIR) band (-, -) remain relatively poorly developed compared to their c…
Linear and Nonlinear Edelstein Effects in Chiral Topological Semimetals
Haowei Xu, Ju Li
Recently, there has been growing interest in achieving on-demand control of magnetism through electrical and optical means. In this work, we provide first-principles predictions fo…
