Combining the quark model, the quark-pair-creation mechanism and $B^{(*)}bar K$ interaction, we have investigated the near-threshold -wave states in the framework of the Hamiltonian effective field theory. With the heavy quark flavor symmetry, all the parameters are determined in the sector by fitting the lattice data. The masses of the bottom-strange partners of the $D^{*}_{s0}(2317)$ and $D^{*}_{s1}(2460)$ are predicted, which are well consistent with the lattice QCD simulation. The two -wave states are the mixtures of the bare core and $B^{(*)}bar K$ component. Moreover, we find a crossing point between the energy levels with and without the interaction Hamiltonian in the finite volume spectrum in the case, which corresponds to a CDD (Castillejo-Dalitz-Dyson) zero in the -matrix of the scattering. This CDD zero will help deepen the insights of the near-threshold states and can be examined by future lattice calculation.

A novel framework is proposed to extract near-threshold resonant states from finite-volume energy levels of lattice QCD and is applied to elucidate structures of the positive parity . The quark model, the quark-pair-creation mechanism and $D^{(*)}K$ interaction are incorporated into the Hamiltonian effective field theory. The bare states are almost purely given by the states with heavy-quark spin bases. The physical $D^*_{s0}(2317)$ and $D^*_{s1}(2460)$ are the mixtures of bare core and $D^{(*)}K$ component, while the $D^*_{s1}(2536)$ and $D^*_{s2}(2573)$ are almost dominated by bare . Furthermore, our model well reproduce the clear level crossing of the $D^*_{s1}(2536)$ with the scattering state at a finite volume.

The isospin violating decays of are revisited in a coupled-channel effective field theory. In a cutoff-independent formalism, we relate the coupling constants of with the two channels to the molecular wave function. The isospin violating decays of are obtained by two equivalent approaches, which amend some deficiencies about this issue in literature. In the quantum field theory approach, the isospin violating decays arise from the coupling constants of to two di-meson channels. In the quantum mechanics approach, the isospin violating is attributed to wave functions at the origin. We bridge the isospin violating decays of to its inner structure. Our results show that the proportion of the neutral channel in is over 80%. As a by-product, we find that the strong decay width and radiative decay width are about 30 keV and 10 keV, respectively, for the binding energy from -300 keV to -50 keV.

Two recently found tetraquark resonances $Z_{cs}$ (3985) and $Z_{cs}$ (4000) are studied in a solvable nonrelativistic effective field theory. We include the possible violations of heavy quark spin symmetry and SU(3) flavor symmetry in a comprehensive approach. Our results show that the decay rates can be used to judge whether these resonances can be different states or not.

We investigate the kinetically allowed strong and electromagnetic decays of the recently observed $T^+_{cc}$ . Our results show that the decay width of $T_{cc}to D^0D^0pi^+$ is the largest one, which is just the experimental observation channel. Our theoretical total strong and radiative widths are in favor of the $T_{cc}$ as a $D^{*+}D^0$ dominated bound state. Our calculation is cutoff-independent and without prior isospin assignment. The absolute partial widths and ratios of the different decay channels can be used to test the structure of $T_{cc}$ state when the updated experimental results are available.

The soft nature of organic-inorganic halide perovskites renders their lattice particularly tunable to external stimuli such as pressure, undoubtedly offering an effective way to modify their structure for extraordinary optoelectronic properties. However, these soft materials meanwhile feature a general characteristic that even a very mild pressure will lead to detrimental lattice distortion and weaken the critical light-matter interaction, thereby triggering the performance degradation. Here, using the methylammonium lead iodide as a representative exploratory platform, we observed the pressure-driven lattice disorder can be significantly suppressed via hydrogen isotope effect, which is crucial for better optical and mechanical properties previously unattainable.

The mass spectrum and strong decays of the S-wave states are studied in the compact tetraquark scenario with the quark model. The model consists of the Coulomb, the linear confinement, and the hyperfine interactions. We calculate their decay amplitudes into the $D^{-(*)}K^{(*)}$ channels using the quark interchange method. The mass and decay width of the state are MeV and MeV, respectively, which indicates that it might be a good candidate for the recently observed state. We also obtain an isospin partner state with MeV and $Gamma_{Xto D^- K}= 48.1$ MeV, respectively. Future experimental search for will be very helpful.

Fission barrier height and its angular-momentum dependence have been measured for the first time in the nucleus with the atomic number greater than 100. The entry distribution method, which can determine the excitation energy at which fission starts to dominate the decay process, was applied to $^{254}$ No. The fission barrier of $^{254}$ No was found to be 6.6 MeV at zero spin, indicating that the $^{254}$ No is strongly stabilized by the nuclear shell effects.

The temperature and energy dependence of spin excitations in an optimally P-doped BaFe(As $_{0.7}$ P $_{0.3}$ ) superconductor (T = 30 K) were studied by using inelastic neutron scattering. Experimental results are consistent with calculations from a combined density functional theory and dynamical mean field theory, and suggest that the decreased average pnictogen height in BaFe(As $_{0.7}$ P $_{0.3}$ ) reduces the strength of electron correlations and increases the effective bandwidth of magnetic excitation.

The decay of a $K^{pi}$ = 8 $^{-}$ isomer in $^{244}$ Pu and the collective band structure populating the isomer are studied using deep inelastic excitations with $^{47}$ Ti and $^{208}$ Pb beams, respectively. Precise measurements of branching ratios in the band confirm a clean 9/2[734] $_{nu}$ 7/2[624] $_{nu}$ for the isomer, validating the systematics of K $^{pi}$ = 8 $^{-}$ two-quasineutron isomers observed in even-, = 150 isotones. These isomers around the deformed shell gap at = 152 provide critical benchmarks for theoretical predictions of single-particle energies in this gateway region to superheavy nuclei.
