Summary: The study provides an overview of Casimir interactions in electronic topological materials over the past decade, focusing on solids with nontrivial topological band structures. Examples include magnetic topological insulators, Chern insulators, graphene monolayers, and Weyl semimetals, each exhibiting unique Casimir properties due to their topological features. The Casimir force generated in these systems may exhibit repulsive behavior due to the orientation of axial vectors, which is topologically protected against weak disorder and could provide signatures of topological quantization in far-field low-temperature behavior.

Summary: This article investigates the Casimir effect in systems consisting of parallel but misaligned finite-size plates. The author explores and elaborates the properties and consequences of the tangential Casimir force from the perspectives of zero-point energy in perfect conductor and dielectric systems.

Summary: Mellin-Barnes (MB) integrals are widely studied objects in mathematics and physics with various applications in different areas. A systematic computational technique for N-fold MB integrals had been lacking until a solution was proposed based on a simple geometrical analysis. This method can handle resonant and nonresonant cases, providing both convergent and diverging series representations depending on the integrand.

Summary: In this study, explicit formulas for the Casimir energy of parallel sheets composed of conducting planes with tensorial conductivities were derived using the scattering matrix approach. Formulas for the Casimir energy and force acting on the planes within a stack of graphene were obtained by solving the recurrence relations. The binding energy in the graphene stack with graphite interplane separation was also calculated and found to be E-ib = 9.9 meV/atom. Notably, the Casimir force on graphene sheets decreases rapidly for planes beyond the first one, with the force on the second graphene layer being 35 times smaller than that experienced by the first layer.

Summary: Inspired by recent progress on classical limits of scattering amplitudes, this study demonstrates that hard thermal loops can be obtained from classical limits of off-shell currents by associating classical wavenumbers to soft particles. The classicality of hard thermal loops is made manifest without the introduction of ghosts, and the classical limit of these currents is computed in QED, QCD, and gravity.

Summary: In this study, the impact-resistant fracture behaviors and energy dissipation mechanisms of MXene were systematically investigated using molecular dynamics simulation. It was found that MXene exhibits a specific penetration energy surpassing conventional impact-resistant materials, and two novel energy dissipation mechanisms were revealed. Furthermore, the atomic-layer structure of MXene can restrain crack propagation, enabling it to retain remarkable resistance.

Summary: This paper addresses the problem of evaluating multiloop Feynman integrals using their Mellin-Barnes representation. After an overview of available capabilities through open source toolkits and their application in different circumstances, a new code MBcreate is introduced, which can automatically derive a concise Mellin-Barnes representation for a given parametric integral. The implementation and use of the code are discussed in detail.

Summary: Advanced energy storage electrode materials should focus on nanoarchitecture, multiple redox states, large surface area, and surface-active sites. This study reports the synthesis of Ni/NiCo2O4 nanosheets decorated onto reduced graphene oxide (rGO) followed by thermal treatment. The resulting nanoarchitecture electrode exhibits a high specific capacitance of 1110 F g-1 at 1 A g-1, demonstrating excellent rate capability. Furthermore, a hybrid supercapacitor constructed using the nanoarchitecture electrode delivers a high specific capacitance of 127 F g-1 and demonstrates excellent long-term cyclability.

Summary: This study investigates nanoporous membranes made from multilayer graphdiyne and finds that they exhibit fast permeation of light gases while suppressing the flow of heavy gases. This phenomenon can be explained by the presence of straight-through holes, where heavy atoms adsorb on the walls, partially blocking the nanoscale permeation.

Summary: The high selectivity of protons over deuterons in one-atom-thick graphene membranes has been experimentally demonstrated, but the underlying mechanism remains controversial. In this study, it is found that proton penetration through perfect graphene is nearly impermeable, while the lowest barrier is observed for lateral ring chemically bonded protons adjacent to hydrogenated hexacyclohydrides. The penetration process involves slip of chemically bonded protons into C-C to form C-H-C bridge bonds, followed by flipping over the graphene membrane.

Summary: By using fluctuating paths of least time compatible with quantum mechanics, a new interpretation in geometrical optics is provided for the interference pattern of Young's double slit experiment, suggesting that the wave behavior of matter and radiation is determined by space-time geodesics. Furthermore, associating a wave function with each path of least time as a probability amplitude and introducing uncertainty for momentum and position can derive the Schrodinger's equation from geodesic characteristics. A new understanding is gained on the van der Waals torque and Casimir attraction/repulsion mechanism.

Summary: Bose-Bose droplets are self-bound objects formed from a mixture of interacting Bose-Einstein condensates, breaking three continuous symmetries in the system. This study provides analytic expressions for zero-energy excitations and introduces Hamiltonians for the dynamics of droplet motion and wavefunction phase evolution. By focusing on a few key degrees of freedom, such as droplet center of mass and wavefunction phases, the complex quantum system can be described effectively, which may have applications in studying low energy collisions of quantum droplets.

Summary: This paper presents a method for predicting forced resonances in nonlinear systems by considering energy balancing and harmonic phase shifts. By combining the energy balancing mechanism with restrictions on external forcing and harmonic phase shifts, a semi-analytical framework is derived to achieve accurate, robust, and efficient computations. Several examples are provided to demonstrate the applicability of this method and the significance of accurately predicting the role of multiple harmonics in the response.
