As two-dimensional (2D) semiconductor devices demand ever higher performance and tunable photo-energy responses, the ability to probe and control exciton-trion interconversion has attracted much attention. However, conventional optical studies predominantly rely on far-field schemes, which suffer from inherent limitations, such as low spatial resolution and weak photoluminescence signals, restricting practical applications. To address these challenges, plasmonic structures have been em

Precision measurements and reliable predictions of nuclear masses are pivotal in advancing nuclear physics and astrophysics. In this paper, we review recent progress in constructing a microscopic nuclear mass table based on the deformed relativistic Hartree-Bogoliubov theory in continuum (DRHBc) that simultaneously incorporates deformation and continuum effects. We present the predictive power and accuracy of the DRHBc mass table, highlighting its diverse applications and extensions. W

The quest to unravel the intricacies of high-Tc superconductivity and strongly correlated electrons in cuprates has spurred a novel focus on direct probing of the CuO2 planes through scanning tunneling microscopy. Infinite-layer (IL) cuprates, featuring a CuO2-terminated surface, emerge as optimal systems for this investigation. Leveraging controllable growth via molecular beam epitaxy, both electron- and hole-doped IL cuprates are realized, with surface structure and c-axis length ser

By using the exact Bethe wavefunctions of the one-dimensional Hubbard model with N spin-up fermions and one spin-down impurity, we derive an analytic expression of the impurity form factor, in the form of a determinant of a \((N+1)\) by \((N+1)\) matrix. This analytic expression enables us to exactly calculate spectral properties of one-dimensional Fermi polarons in lattices, when the masses of the impurity particle and the Fermi bath are equal. We present the impurity spectral functio

Dark states, which are incapable of absorbing and emitting light, have been widely applied in multiple disciplines of physics. However, the existence of dark states relies on certain strict constraints on the system. For instance, in the fundamental \(\Lambda\) system, a perturbation breaking the degeneracy between two energy levels may destroy the destructive interference and demolish the dark state. Here, we show that non-Hermiticity can be exploited as a constructive means to restor

Particle accelerators, originally developed to address fundamental questions about the universe, have become essential to various scientific disciplines. The broad adoption of accelerators was enabled by substantial advancements in beam manipulation techniques, which encompass methods for generating and controlling particle beams to optimize them for specific applications. Most of these manipulations rely on controlling the beam’s correlation in its phase space. While linear control an
