Effects of high-pressure on the structural, vibrational, and electronic properties of monazite-type PbCrO4

Bandiello, E.; Errandonea, D.; Martinez-Garcia, D.; Santamaria-Perez, D.; Manjón Herrera, Francisco Javier (American Physical Society, 2012-01-12)

We have performed an experimental study of the crystal structure, lattice dynamics, and optical properties of PbCrO 4 (the mineral crocoite) at ambient and high pressures. In particular, the crystal structure, Raman-active ...
High-pressure study of ScVO4 by Raman scattering and ab initio calculations

Panchal, V.; Manjón Herrera, Francisco Javier; Errandonea, D.; Rodriguez-Hernandez, P.; López-Solano, J.; Muñoz, A.; Achary, S.N.; Tyagi, A.K. (American Physical Society, 2011-02-25)

We report results of experimental and theoretical lattice-dynamics studies on scandium orthovanadate up to 35 GPa. Raman-active modes of the low-pressure zircon phase are measured up to 8.2 GPa, where the onset of an ...
Homomorphisms between algebras of holomorphic functions

Dimant, Verónica; García, Domingo; Maestre, Manuel; Sevilla Peris, Pablo (Hindawi Publishing Corporation, 2014)

For two complex Banach spaces X and Y, in this paper, we study the generalized spectrum M-b(X,Y) of all nonzero algebra homomorphisms from H-b(X), the algebra of all bounded type entire functions on X into H-b(Y). We endow ...
La enseñanza problematizada de la física cuántica en el bachillerato y en los cursos introductorios de física

Savall Alemany, Francisco; Domènech Blanco, Josep Lluís; Martínez Torregrosa, Joaquín; Rey Cubero, Alexandra; Rosa Cintas, Sergio (Universitat Politècnica de València, 2016-01-31)

[EN] The e ectiveness of the problem based teaching on the science learning has been highlighted by the didacticresearch. This teaching model is characterized by organizing the units around problems and by proposinga ...
Mean ergodic and related properties of generalized Cesàro operators in BK-sequence spaces

Albanese, Angela A.; Bonet Solves, José Antonio; Ricker, Werner J. (Springer-Verlag, 2024-11-05)
