Breaking Down a Relationship Break-up: Potential Landscape as a Physics-Inspired Dynamical Model of Interpersonal Communication

A physics-inspired dynamical model of interpersonal communication is proposed to describe how information interpretation can influence the evolution of a relationship between two interacting systems. The model distinguishes between intended information and observed information, with the former represented as an asymptotic limit in an abstract information space. An information potential landscape with local minima and increasing potential barriers is introduced to represent stable information states and limited information accessibility. Information transmission and processing are described through a general thought-processing function, while the separation between information states determines the coupling strength between the interacting systems. The relationship dynamics is then defined from the coupling strength and the independent sentiments of the two systems. Numerical simulations demonstrate the potential landscape, information dynamics, and several relationship regimes under deterministic and fluctuating information processing. An illustrative dynamical scenario further shows that an emerging information discrepancy can lead to either relationship recovery or deterioration depending on the subsequent evolution of information separation, coupling, and individual sentiment. The model provides a simple physics-inspired framework for describing interpersonal communication as a coupled dynamical process.

Effective Mass in Quantum Hadrodynamics-I and its Impact on the Equation of State of Neutron Matter

The effective nucleon mass (M^*) plays a central role in Quantum Hadrodynamics-I (QHD-I), linking scalar meson interactions at the microscopic level to the macroscopic properties of dense nuclear matter. In this work, we re-derive the scalar density integral in detail and validate it numerically using Gaussian quadrature. The numerical and analytic results are found to be in excellent agreement, confirming the robustness of both approaches. We then investigate the sensitivity of M^* to different parameter sets, highlighting its strong influence on nuclear saturation, compressibility, and the resulting equation of state (EoS). The analysis shows that variations in meson-nucleon couplings propagate directly into differences in pressure and energy density, affecting the stiffness of the EoS. While QHD-I produces characteristically stiff EoS, the effective mass evaluation provides a transparent framework for connecting microscopic meson dynamics to macroscopic neutron star properties. These findings underline the relevance of M^* as a microscopic-macroscopic bridge and demonstrate the utility of numerical methods for extending relativistic mean-field models in nuclear astrophysics.
