Electrically reconfigurable dipolar polaritons with highly tunable nonlinearity in a homobilayer microcavity

Baixu Xiang, Yubin Wang, Guihan Wen +9

Active control over optical nonlinearity in solid-state systems is central to unlocking exotic many-body phenomena and photonic devices. While exciton-polaritons in transition meta…

Optical Detection and Manipulation of Pseudospin Orders in Wigner Crystals

Yichen Dong, Eugene Demler, Zhiyuan Sun

In Wigner-crystal states of two-dimensional electrons, the spin ordering remains poorly understood. The small energy differences between candidate spin orders make theoretical stud…

Ab initio Approach to Collective Excitations in Excitonic Insulators

Fengyuan Xuan, Jiexi Song, Zhiyuan Sun

An ab initio approach is presented for studying the collective excitations in excitonic insulators, charge/spin density waves and superconductors. We derive the Bethe-Salpeter-Equa…

Supercurrent Growth in Nonequilibrium Superconductors

Qinghong Yang, Yuqi Cao, Dante M. Kennes +1

In ultrafast experiments on superconductors, a pump laser pulse often heats up the electronic system and suppresses the density of superfluid electrons. Subsequently, the electrons…

Observation of Local Pairs through Nonequilibrium Terahertz Spectroscopy in YBa2Cu3O7-δ Below Tc

Jinzhong Zhang, Qingming Huang, Zhangqiang Yang +2

Pairing states are essential to understanding the underlying mechanisms of high-temperature superconductivity. Here the non-superconducting state in an optimally doped YBa_2 Cu_3 O…

Fate of transient order parameter domain walls in ultrafast experiments

Lingxian Kong, Ryuichi Shindou, Zhiyuan Sun

In ultrafast experiments, an optical pump pulse often generates transient domain walls of the order parameter in materials with spontaneous symmetry breaking, due to either a finit…
