Summary: This study presents a simple design of Fabry-Perot cavities with longitudinal chiral modes. By sandwiching a layer of polystyrene made planar chiral by torsional shear stress between two smooth metallic silver mirrors, the helicity-preserving features of the cavities are achieved through a spin-orbit coupling mechanism rooted in the specific chiroptical features of planar chirality. The extrinsic source of three-dimensional chirality under oblique illumination gives rise to enantiomorphic signatures of the cavities, which are experimentally measured and simulated with excellent agreement.

Summary: The photonic spin Hall effect allows for quantifying the interaction between light and spin-orbit, enabling applications in precise metrology. In this effect, the light beam experiences a spin-dependent transverse shift. It is found that, unlike the reflection/transmission process, the transverse shift for transmitted light is always zero and independent of polarization, regardless of the incident angle. This is due to the complete suppression of conversion between the spin and orbital angular momenta of light during the transmission process. Similar polarization-independent photonic spin Hall effect is observed for reflected light.

Summary: The study found that the charge voltages generated by two counterpropagating spin currents in the Ag/Bi interface show opposite signs, consistent with the inverse spin Hall effect rather than the inverse Rashba-Eldestein effect. Using femtosecond laser to generate spin-current-induced terahertz signal in the Ag/Bi bilayer also showed no evidence for the inverse Rashba-Eldestein effect. This work provides a clear-cut method to identify the spin-to-charge mechanism in a Rashba electronic state and delivers new understanding for the relevant spin-transport phenomena.

Summary: Intrinsic spin-momentum locking is a fundamental property of surface electromagnetic fields, with important implications in various fields. Previous studies have ignored dispersion, leading to contradictions with physical reality. In this study, we present four dispersive spin-momentum equations that reveal the relationship between spin and momentum. Additionally, the locking behavior is influenced by structural features. By engineering rotational symmetry, the properties of spin-momentum locking can be identified in different photonic topological lattices.

Summary: This study presents a mechanism of optical isolation by integrating the unique dispersion of hyperbolic metamaterial with the transverse spin-orbit interaction of evanescent waves. By rotating subwavelength hyperbolic nanoparticles, more than 95% isolation of infrared light can be achieved at an experimentally feasible rotation speed. This new type of optical isolation device can be applied in optical communications, chiral quantum optics, and topological photonics.

Summary: This study reports enantiomeric organic chiral ferrimagnets, where chirality is formed by the molecular torsion caused by the propeller-like arrangement of the donor and acceptor molecules. These materials could bridge the gap between ferromagnetism and antiferromagnetism, making them significant in the field of organic spintronics.

Summary: In this study, we investigate the effective equation of motion for Sn1-xEuxTe material using the effective mass representation based on the fundamental six-level double group basis. The analysis takes into account the spin-orbit interaction, external magnetic field, and impurity effects. Our results show that the material exhibits a very high effective g factor with significant anisotropy in a specific concentration range, making it a potential candidate for spintronics applications.

Summary: The binary and ternary telluride systems containing europium as one of the magnetic components exhibit a higher effective g factor and much lower effective mass due to spin-orbit interaction and s/p-f hybridized interaction. In this study, we investigated the ternary mixed crystal Sn1-xSrxTe, with strontium as the non-magnetic counterpart of europium, and derived functional equations and expressions for the effective g factor and effective mass. The results show that Sn1-xSrxTe has extremely elevated effective g factors and low effective mass, suggesting strong spin-orbit interaction and band edge coupling induced by substitutional impurity.

Summary: A hyperon-nucleon potential for the S = -1 sector up to third order in the chiral expansion is introduced, considering both the SU(3) flavor symmetry and explicit SU(3) symmetry breaking. An innovative regularization scheme is used, leading to an excellent description of scattering data and the analysis of new data from J-PARC. Results for hypertriton and A = 4 hyper-nuclear separation energies are presented, along with an uncertainty estimate for selected observables in the hyperon-nucleon system.

Summary: In this review, the current understanding of the excited strongly interacting particle spectrum is presented. The systematic and model-independent calculation methods, namely lattice QCD and effective field theories, are discussed. The synergies between these approaches can provide a deeper understanding of the hadron spectrum. The use of the Breit-Wigner parametrization is shown to be inconsistent with chiral symmetry and should be avoided in strongly coupled channels.

Summary: The internal structure of charm-strange mesons D-s0*(2317) and D-s1(2460) is being extensively studied. Their narrow widths are due to their dominant decay through isospin-breaking hadronic channels. The decay of D-s1(2460) can also occur through hadronic final states with isospin conservation, but is strongly suppressed due to phase space limitations. By considering the Ds1(2460) as a D*K hadronic molecule, we find that the predicted partial widths and the pi(+)pi(-) invariant mass distribution are consistent with experimental measurements, and suggest possible ways to distinguish between the hadronic molecular and compact state pictures for the D-s1(2460)(+). Predictions for B-s1(0) -> B-s(0) pi(+) pi(-) are also made.

Summary: The carbon atom is the backbone of organic chemistry and has a complex nucleus in its predominant isotope, C-12. In this study, a model-independent density map of the nuclear states of C-12 is provided using nuclear lattice effective field theory. The well-known Hoyle state is found to have a bent-arm or obtuse triangular arrangement of alpha clusters. All low-lying nuclear states of C-12 are identified as having an intrinsic shape composed of three alpha clusters forming either an equilateral triangle or an obtuse triangle.

Summary: We propose a new finite-volume approach based on an Effective Field Theory Lagrangian to implement two- and three-body dynamics in a transparent way. The formalism utilizes a particle-dimer picture and formulates the quantization conditions based on the self-energy of the decaying particle. The study focuses on the Roper resonance, utilizing input from lattice QCD and phenomenology, and predicts finite-volume energy eigenvalues, which are then compared to existing lattice QCD calculations as initial guidance for precision requirements.

Summary: Using dispersion theory, the Sigma-to-Lambda transition form factors in electromagnetic interactions are calculated considering the pion electromagnetic form factor, SU(3) chiral perturbation theory, the baryon decuplet, and the pi pi- K coupled-channel effect. The electric form factor is significantly affected by the inclusion of the K channel, while the magnetic form factor is minimally affected. The uncertainties in the three-flavor chiral perturbation theory are estimated using a bootstrap sampling method.

Summary: Using an effective Lagrangian with heavy quark spin symmetry, this study investigates the coupled-channel dynamics of the doubly charmed systems D-(*) Sigma((*))(c). The potential considered includes exchanges of pseudoscalar and vector mesons in the t-channel. By applying the first iterated solution of the N/ D method, several S-wave bound states with isospin I = 1/2 are discovered. These states correspond to open-charm partners of the hidden charm pentaquarks P-psi(N) observed by the LHCb Collaboration.

Summary: This study presents a microscopic investigation of the electromagnetic properties of the low-lying states of single-A hypernucleus 9ABe using the HyperGCM method based on covariant density functional theory. The results are compared to those of a particle-rotor model (PRM) and show close agreement. It is found that the electric quadrupole transition strengths are more sensitive to the coupling strengths of the AN interaction than the magnetic moments and M 1 transition strengths.
