Texto completoOscillatory neuronal activity is an omnipresent phenomenon in the cerebral cortex. However, the actual function of these oscillations remains unclear. Are they just an epiphenomenon of elevated firing rates or do they represent a fundamental process on their own? Based on experimental work, we apply computational modeling to address this question. We first study the role of oscillations in attentional processes and then in a more general, information theoretical context. Our results support the idea that oscillations represent an independent mechanism. In particular, we show that attention modulates gamma oscillations independently of rates and that the flow of information between brain areas depends both on the phase and on the spectral power of oscillations. Moreover, we show that the speed of information exchange increases as a function of spectral power in specific frequency bands. Taken together, these results suggest that oscillations are a mechanism employed by the brain to control actual interactions between brain areas and thus likely have a link to behavior.

Texto completoThe topic of this work deals with theoretical and experimental study of the control of ultrashort pulse coherent propagation in optically dense medium. First, we describe the basics of propagation phenomena. Secondly, we study the idea of using a strong driving pulse, to control the transient properties of a weak resonant pulse simultaneously propagating in the medium. The strong field induces transient modifications in the medium, which modify the electric field of the weak resonant propagating pulse. Finally, we study a configuration where two orthogonally polarized pulses, excite resonantly a four level system degenerated two by two. With the strong field mixing the states, the emission and absorption path of the weak field have similar contribution. The two paths interfere thus modulating the transmitted pulse energy. The interplay of the light shift and the interference enables us to control the gain and the pulse temporal shape as well

Texto completoFemtosecond pump and probe techniques are standard experimental methodologies used for studying ultrafast dynamics in solids, in particular phonon oscillations in target materials. So far, only semiclassical methods have been employed in order to theoretically interpret the experimental data. In contrast, a fully quantum treatment will be presented here taking into account the quantum features of the generation mechanism of excited phonons by pump laser pulses, and of the process of accessing their behaviour by probe laser pulses. A single effective Hamiltonian will be used to model the interaction between photons and phonons both for the pumping and probing processes. In addition, as they interact with their environment, mainly electrons in the target, the excited phonons cannot be considered an isolated system. Their dynamics is then that typical of open quantum systems and generated by a master equation of Lindblad form, that takes into account the dissipative and noisy effects due to the environment.In this formalism, phonon oscillations can be analysed through suitable probe photon observables. Specifically, unlike in the existing literature, we will not focus only upon the scattered probe pulse intensity, namely on the probe photon number, but also on the number variance. Through the latter some quantum features of the phonon state can be accessed; in particular, specific signals of the presence of squeezed phonons can thus be identified.
Le tecniche di "pump and probe" impulsato sono metodologie sperimentali standard usate nello studio delle dinamiche ultraveloci nei solidi, in particolare delle oscillazioni di fononi. Usualmente l'interpretazione teorica dei dati sperimentali si basa su approssimazioni semiclassiche. Una descrizione completamente quantistica e` invece sviluppata nella presente trattazione: e` basata sull'introduzione di un'unica hamiltoniana di interazione tra fotoni e fononi, capace di descrivere in modo effettivo sia il processo di eccitazione che di rivelazione dei fononi. In generale, tali fononi non possono essere considerati come isolati, ma costituiscono un sistema quantistico aperto, cioe` in interazione debole con l'ambiente esterno, formato principalmente da elettroni e dagli altri costituenti del materiale in studio. La loro dinamica deve percio` venir descritta tramite una equazione master, che tenga conto di effetti di rumore e dissipazione. In questo formalismo, le proprieta` dei fononi eccitati dagli impulsi laser di "pump" possono essere analizzate attraverso lo studio di opportune osservabili caratterizzanti i fotoni di "probe". Piu` specificatamente, si e` analizzato il comportamento non solo dell'intensita` media della luce di "probe" riflessa, cioe` del numero medio di fotoni, ma anche della relativa varianza. In questo modo, si possono evidenziare alcune caratteristiche quantistiche dei fononi: in particolare, sono stati individuati segnali specifici della presenza di fononi "squeezed"
