Ferroelastic twin wall mediated ferro-flexoelectricity and bulk photovoltaic effect in SrTiO
Ri He, Haowei Xu, Peijun Yang +3
Ferroelastic twin walls in nonpolar materials can give rise to a spontaneous polarization due to symmetry breaking. Nevertheless, the bi-stable polarity of twin walls and its rever…
Precise Fermi-level engineering in a topological Weyl semimetal via fast ion implantation
Manasi Mandal, Abhijatmedhi Chotrattanapituk, Kevin Woller +10
The precise controllability of the Fermi level is a critical aspect of quantum materials. For topological Weyl semimetals, there is a pressing need to fine-tune the Fermi level to…
Solid-State Nuclear Laser with Two-Photon Pumping
Haowei Xu, Hao Tang, Guoqing Wang +4
The radiative excitation of the 8.3 eV isomeric state of thorium-229 is an outstanding challenge due to the lack of tunable far-ultraviolet (F-UV) sources. In this work, we propose…
Two-photon Interface of Nuclear Spins Based on the Opto-Nuclear Quadrupolar Effect
Haowei Xu, Changhao Li, Guoqing Wang +5
Photons and nuclear spins are two well-known building blocks in quantum information science and technology. Establishing an efficient interface between optical photons and nuclear…
Laser Cooling of Nuclear Magnons
Haowei Xu, Guoqing Wang, Changhao Li +5
The initialization of nuclear spin to its ground state is challenging due to its small energy scale compared with thermal energy, even at cryogenic temperature. In this Letter, we…
Nonlinear Nonreciprocal Photocurrents under Phonon Dressing
Haowei Xu, Hua Wang, Ju Li
Nonlinear optical (NLO) effects have attracted great interest recently. However, by far the computational studies on NLO use the independent particle approximation and ignore many-…
