Low-temperature electron-phonon heat transfer in metal films
S. Cojocaru, D. V. Anghel
We consider the deformation potential mechanism of the electron-phonon coupling in metal films and investigate the intensity of the associated heat transfer between the electron an…
Electron-phonon heat exchange in layered nano-systems
Dragos-Victor Anghel, Sergiu Cojocaru
We analyze the heat power between electrons and phonons in thin metallic films deposited on free-standing dielectric membranes in a temperature range in which the phonon gas ha…
Modification of the Bloch law in ferromagnetic nanostructures
S. Cojocaru, A. Naddeo, R. Citro
The temperature dependence of magnetization in ferromagnetic nanostructures (e.g., nanoparticles or nanoclusters) is usually analyzed by means of an empirical extension of the Bloc…
Isotope effect and bond-stretching phonon anomaly in high-Tc cuprates
S. Cojocaru, R. Citro, M. Marinaro
We analyse a model where the anomalies of the bond-stretching LO phonon mode are caused by the coupling to electron dynamic response in the form of a damped oscillator and explore…
Green's functions on finite lattices and their connection to the infinite lattice limit
S. Cojocaru
It is shown that the Green's function on a finite lattice in arbitrary space dimension can be obtained from that of an infinite lattice by means of translation operator. Explicit e…
Incoherent mid-infrared charge excitation and the high energy anomaly in the photoemission spectra of cuprates
S. Cojocaru, R. Citro, M. Marinaro
On the basis of a semi-phenomenological model, it is argued that the high energy anomaly observed in recent photoemission experiments on cuprates is caused by interaction with an o…
