Summary: We examine the combined effects of finite volume and an external magnetic field on the charged two-pion correlation function. The results show that for slow pions, there is a large distortion in the correlation function compared to the case of large average pair momentum. In a finite density system, the intercept of the correlation function decreases, indicating the increasing importance of the pion ground state contribution. Increasing the strength of the magnetic field reduces the importance of the ground state and brings the intercept closer to 2.

Summary: This paper investigates the standard measures of bipartite entanglement in one-dimensional quantum field theories, finding that they can be expressed in terms of correlators of branch point twist fields. It also reveals the role of other twist fields, known as composite twist fields, in the study of symmetry resolved entanglement entropy. The paper provides an exact expression for the two-point function of a composite twist field in the Ising field theory.

Summary: The study found that the heat capacity peak position and amplitude of two-dimensional semiconducting nanoporous superlattices are tunable, and researchers can adjust these quantities to desired values based on specific parameters. Compared to four different semiconducting systems, the AlxGa1-xAs system showed better heat capacity adjustability.

Summary: This study explores the description of molecular symmetry in static external magnetic fields using group theory, presenting a general scheme for identifying the molecular point group under such conditions and providing character tables for point groups that are non-existent in the absence of a field. It is mathematically proven that all possible point groups are Abelian.

Summary: A stable volume integral equation (VIE) solver based on polarization/magnetization currents is presented for accurate and efficient computation of electromagnetic scattering. The formulation is discretized using the Galerkin method with discontinuous piecewise linear basis functions on uniform voxelized grids, allowing for accelerated matrix-vector products in an iterative solver with the help of FFT.

Summary: A new 2D formulation is developed to analyze the effects of magnetic and electric fields on the bending behavior of magneto-electro-elastic nanobeams. The accuracy of the model is improved by considering a general displacement field and using the nonlocal elasticity theory. The results show that the present method can predict the deflection of nanobeams more accurately compared to existing shear deformation theories.

Summary: This study demonstrates that molecules containing vibrational Stark shift reporters can be used to measure DC electric fields in situ. However, it is found that the uniform field DFT calculations cannot accurately model the behavior of the three strongest vibrational modes in molecules forming a monolayer on an electrode. It is shown that the measured Stark shifts are explained by partial electrical double-layer penetration into the molecular layer, which is sensitive to the local environment.

Summary: This paper analyzes the static fields of a grounding grid and proposes a method to evaluate its robustness by calculating the resistance of the grid. Unlike existing methods, the proposed method does not require tedious calculations and is immune to noise induction. The feasibility and accuracy of the proposed approach are demonstrated through a comparison with one of the latest research studies.

Summary: This study investigated the impact of age on the electric fields induced by transcranial magnetic stimulation (TMS) in different anatomical regions of the brain. The results showed a negative correlation between age and electric field peaks in different brain tissues, with children exhibiting the widest distribution of electric fields. These findings underscore the importance of safety considerations for TMS applications and protocols in children.

Summary: This study investigates the combined effects of hydrogenic impurity, core radius and layer thickness, and external electric and magnetic fields on the third harmonic generation (THG) of core/shell/well/shell spherical quantum dots. The study used the 2D finite difference method within the effective mass approximation to obtain wavefunctions and energy values. The results show that the THG coefficient is mainly influenced by the external fields and the sizes of the core, barrier, and well regions. Additionally, the presence of on-center hydrogenic donor impurity significantly reduces the magnitude of THG at certain potential parameter values.

Summary: This study investigates the influence of rotation on the transition temperature of strongly interacting matter produced in non-central heavy ion collisions. By using a holographic description of an AdS black hole, the authors extend the analysis to the more realistic case where the matter spreads over a region around the rotational axis. The results show the coexistence of confined and deconfined phases and are consistent with the concept of local temperature in rotating frames developed by Tolman and Ehrenfest.

Summary: This paper investigates the effect of gravitational constant variation on the propagation of gravitational waves. By employing two analytical methods, the study finds that variations in the gravitational constant result in amplitude and phase corrections for gravitational waves, and the time variation of the gravitational constant can be constrained through the propagation of gravitational waves.

Summary: This letter presents the first study of Hawking radiation as a tunneling process within the framework of non-commutative gauge theory of gravity. The non-commutative Schwarzschild black hole is reconstructed using the Seiberg-Witten map and the star product. The emission spectrum of outgoing massless particles is computed using the quantum tunneling mechanism. The results reveal pure thermal radiation in the low-frequency scenario, but a deviation from pure thermal radiation in the high-frequency scenario due to energy conservation. It is also found that noncommutativity enhances the correlations between successively emitted particles.

Summary: The travel times of light signals between two antipodal points on a compact star's surface are calculated for two different trajectories. It is shown that, for highly dense stars, the longer trajectory along the surface may have a shorter travel time as measured by asymptotic observers. A critical value of the dimensionless density-area parameter is determined for constant density stars to distinguish cases where crossing through the star's center or following a semi-circular trajectory on the surface has a shorter travel time as measured by asymptotic observers.
