Summary: This study proposes the emergence of robust magnetic topological insulators in two-dimensional ferromagnets, regardless of magnetization directions. The 2H-RuCl2 and Janus VSSe monolayers are identified as experimentally feasible candidates of such insulators. It is also found that the valley polarization of SOTIs can be significantly greater than that of known ferrovalley materials under out-of-plane magnetization.

Summary: The structural and electronic properties of two-dimensional honeycomb boron on the Al(111) substrate have been elucidated through a combination of experimental techniques and theoretical calculations. It is found that honeycomb boron induces reconstruction of the top metal layer, forming a stoichiometric AlB2 sheet on top of Al, in contrast to graphene behavior on lattice-mismatched metal surfaces. The electronic states of honeycomb boron exhibit a clear separation into pi- and sigma-subsystems, indicating the 2D nature of the electronic system in both mono-layer AlB2 and bulk AlB2.

Summary: Hepatocellular carcinoma (HCC) is a highly deadly tumor with a significant rate of recurrence and metastasis. Cancer stem cells (CSCs) play a crucial role in these processes, providing a new perspective on liver cancer development. A study utilized composite magnetic nanocubes modified with polyethyleneimine (PEI) and hyaluronic acid (HA) to target HCC stem cells. The nanocubes successfully recognized the stem cells through receptor-ligand binding. The study also showed that the nanocubes inhibited HCC cell proliferation and migration by regulating the expression of epithelial-mesenchymal transition (EMT) markers.

Summary: A search is conducted for interactions from solar 8B neutrinos elastically scattering off xenon nuclei using PandaX-4T commissioning data. The energy threshold for this search is lowered compared to previous dark matter searches, and various techniques are employed to suppress background. Analyzing the data with an effective exposure of 0.48 tonne year, no significant excess of events is observed. The study provides the most stringent constraint on the solar 8B neutrino flux and a more stringent limit on the cross section between dark matter and nucleon in the mass range from 3 to 9 GeV/c2.

Summary: A long-standing pursuit in materials science is to identify suitable magnetic semiconductors for integrated information storage, processing, and transfer. Van der Waals magnets have brought forth new material candidates for this purpose. Recently, sharp exciton resonances in antiferromagnet NiPS3 have been reported to correlate with magnetic order, that is, the exciton photoluminescence intensity diminishes above the Neel temperature. Here, it is found that the polarization of maximal exciton emission rotates locally, revealing three possible spin chain directions. This study shows that anisotropic exciton photoluminescence can be used to read out local spin chain directions in antiferromagnets and realize multi-functional devices via spin-photon transduction.

Summary: Transition-metal dichalcogenides (TMDs) have exhibited various novel phenomena in photonics, optoelectronics, and correlated electron effects. However, the coherent dynamics of excitons in TMDs are not well understood, particularly their sensitivity to spatial heterogeneities. In this study, adiabatic plasmonic nanofocused four-wave mixing was used to visualize the coherent electron dynamics in monolayer WSe2, revealing nanoscale heterogeneities at room temperature with dephasing times ranging from a few femtoseconds to tens of femtoseconds. Surprisingly, the intensity of four-wave mixing emission was found to be weakest at locations with the longest coherence, indicating a nonlocal nano-optical interplay between spatial coherence and disorder-induced scattering.

Summary: When mobile impurities are introduced and coupled to a Fermi sea, new quasiparticles called Fermi polarons are formed. There are two regimes of the Fermi polaron problem: attractive polarons (AP) connected to pairing phenomena, and repulsive polarons (RP) responsible for ferromagnetism. In this study, we investigate Fermi polarons in a doped MoSe2 monolayer and find agreement with polaron theory for attractive polarons. The dynamics of Fermi polarons are important for understanding pairing and magnetic instabilities in various physical systems.

Summary: We used sum-frequency phonon spectroscopy to directly observe lattice phonons confined at LaAlO3/SrTiO3 (LAO/STO) interfaces and STO surfaces. This interface-specific nonlinear optical technique revealed phonon modes localized within a few monolayers at the interface, with inherent sensitivity to the coupling between lattice and charge degrees of freedom. We also discovered a characteristic lattice mode from interfacial oxygen vacancies, enabling us to probe such important structural defects in situ. Our study provides a unique perspective on many-body interactions at the correlated oxide interfaces.

Summary: For electron optics in graphene, the only available physical mechanism has been the propagation effect. However, this results in large-sized electronic components that need to operate at low temperatures. This paper introduces the concept of electron metasurfaces in graphene, which are the electronic counterparts of optical metasurfaces. The metasurfaces allow for the bending and splitting of electron beams, with the functionalities controlled by applied gate biases. These electron metasurfaces can shape the wavefront of electron beams within a short distance at room temperature, enabling the realization of optics-inspired electronic devices that can operate under ambient conditions. The concept of metasurface electron optics also holds promise for applications such as electron metalenses, metasurface holography, and metasurface-based digital coding technology in graphene.
