#### Entangling two exciton modes using exciton optomechanics

Author(s): Xuan Zuo, Zhi-Yuan Fan, Huai-Bing Zhu, and Jie LiExciton optomechanics, bridging cavity exciton polaritons and optomechanics, opens new opportunities for the study of light-matter strong interactions and nonlinearities, due to the rich nonlinear couplings among excitons, phonons, and photon

#### Entangled three-particle states and phonon pairs in an optomechanical system with quadratic mechanical-displacement coupling

Author(s): Yan Liu, Zhentao Zhang, and Zhenshan YangWe study the generation of three-particle (one photon plus two phonons) states and phonon pairs in a cavity-waveguide system where the optomechanical coupling is quadratic in the mechanical displacement.

#### Thermal decay of planar Jones-Roberts solitons

Author(s): Nils A. Krause and Ashton S. BradleyHomogeneous planar superfluids exhibit a range of low-energy excitations that also appear in highly excited states like superfluid turbulence.

#### Excitations of a two-dimensional supersolid

Author(s): E. Poli, D. Baillie, F. Ferlaino, and P. B. BlakieWe present a theoretical study of the excitations of the two-dimensional supersolid state of a Bose-Einstein condensate with either dipole-dipole interactions or soft-core interactions.

Author(s): Shiyan Gong, Peng Wang, and Yuxiang MoWe present experimental observations of parity-mixed rotational states in the a3Π1,2 states of the CO molecule induced by an electric field of ∼600 V/cm.

#### Performance advantage of discriminating one-versus-two incoherent sources based on quantum hypothesis testing

Author(s): Jian-Dong Zhang, Mei-Ming Zhang, Chuang Li, and Shuai WangDetecting the presence of multiple incoherent sources is a fundamental and challenging task for quantum imaging, especially within sub-Rayleigh region.

#### Fast charging of an Ising-spin-pair quantum battery using optimal control

Author(s): Vasileios Evangelakos, Emmanuel Paspalakis, and Dionisis StefanatosWe consider the problem of maximizing the stored energy for a given charging duration in a quantum battery composed of a pair of spins-1/2 with Ising coupling starting from the spin-down state, using bounded transverse field

#### Information scrambling in quantum walks: Discrete-time formulation of Krylov complexity

Author(s): Himanshu SahuWe study information scrambling (a spread of initially localized quantum information into the system's many degree of freedom) in discrete-time quantum walks.

#### Synchronization and asynchronization in non-Hermitian systems

Author(s): Qi Hong, Wen-Xin Wu, Yuan-Peng Peng, Jie Qian, Can-Ming Hu, and Yi-Pu WangSynchronization and asynchronization are ubiquitous occurrences in a wide range of natural and artificial systems.
