In this paper, we study the effects of magnetic field and initial stress on p-, T-, and SV-waves propagation. We investigated the problem of reflection and refraction of thermoelastic waves at a magnetized solid-liquid interface in the presence of initial stress. In the context of classical theory and Green-Lindsay theory of thermoelasticity, the problem has been solved. The boundary conditions applied at the interface are: (i) displacement continuity; (ii) vanishing tangential displacement; (iii) continuity of normal force per unit initial area; (iv) tangential force per unit initial area must vanish; and (v) continuity of temperature. The amplitudes ratios for the incident p-, T-, and SV-waves have been obtained. The reflection and transmittion coefficients from the incident waves are computed numerically, considering the initial stress and magnetic field effect and the results obtained have been presented graphically. PACS Nos.: 46.25.-y, 46.35.+Z. Nous etudions ici les effets d'un champ magnetique et d'une contrainte initiale sur la propagation d'ondes p, T et SV. Nous nous interessons au probleme de reflexion et de refraction d'ondes thermo-elastiques a des interfaces solide- liquide magnetisees, avec des contraintes initiales. Nous solutionnons le probleme dans le cadre de la theorie classique (CT) et de la theorie de Green-Lindsay (GL) de la thermo-elasticite. Les differentes conditions limites imposees a l'interface sont (i) continuite des deplacements, (ii) annulation du deplacement tangentiel, (iii) continuite de la force normale par unite de surface, (iv) annulation de la force tangentielle par unite de surface et (v) continuite de la temperature. Nous obtenons les rapports d'amplitude pour des ondes p, T, et SV incidentes. Nous calculons numeriquement les coefficients de reflexion et de refraction, en tenant compte de la contrainte initiale et de l'effet du champ magnetique et nos resultats sont presentes graphiquement. [Traduit par le Redaction], Introduction Recently, attention has been focused on the theory of thermoelasticity because of its utilitarian aspects in diverse fields, especially, structures mechanics, biology, geology, geophysics, acoustics, physics, plasma, etc. Generalized [...]

Quantum Fisher information (QFI) and geometric phase have recently performed different tasks in quantum information technology. We investigate the statistical quantities as the QFI and entanglement of a three‐level atom in Λ configuration interacting with a quantized field mode by using linear entropy. We study the dynamical behavior of the geometric phase based on the engineering of a three‐level atomic configuration. We analyze the effect of energy dissipation of the dynamical properties of the geometric phase and the QFI as an entanglement quantifier between the three‐level atom and field. We explore the correlation between the engineering geometric phase and QFI in the absence and presence of energy dissipation effect. We have found that the QFI is very sensitive to the effect of the time‐dependent coupling and energy dissipation. [ABSTRACT FROM AUTHOR]
