Nonlinear frequency conversion under general phase mismatched condition: the role of phase locking and random nonlinear domains
In the field of second harmonic (SH) generation most studies have been concerned with maximizing conversion efficiencies, generally achievable at the phase matching (PM) condition. Outside of the PM the conversion efficiency ...

Nonlinear optics with a Rydberg ensemble for quantum information processing purposes
(English) Photons have emerged as the main candidates for carrying quantum information due to their weak interaction with the environment. Unfortunately, their limited interaction with one another poses challenges for ...
Nonlinear pulse compression
In this thesis I investigate two methods for generating ultrashort laser pulses in spectral regions which are ordinarily difficult to achieve by the existing techniques. These pulses are specially attractive in the study ...
Nonlinear signal analysis of micro and macro electroencephalographic recordings from epilepsy patients
The use of nonlinear signal analysis measures to characterize electroencephalographic (EEG) recordings can be key for a better understanding of the underlying brain dynamics. In neurological disorders such as epilepsy, ...
Nonlinear simulation and design of microwave, multi-device distributed autonomous circuits
It is widely believed that many drawbacks in today's wireless communication paradigm might be relieved by enabling high carrier frequency transmission, and endowing both the network and the user equipment with some degree ...
Nonlinear subgrid finite element models for low Mach number flows coupled with radiative heat transfer
The general description of a fluid flow involves the solution of the compressible Navier-Stokes equations, a very complex problem whose mathematical structure is not well understood. It is widely accepted that these equations ...
Nonlocal Lagrangian Formalism
[eng] This thesis aims to study nonlocal Lagrangians with a finite and an infinite number of degrees of freedom. We obtain an extension of Noether's theorem and Noether's identities for such Lagrangians. We then set up a ...
Nonlocal resources for quantum information tasks
This thesis focusses on the essential features of Quantum Theory that are systems in an entangled state and Bell nonlocal correlations. Here, we take the angle of a resource theory and are interested in understanding better ...
Nonlocality in multipartite correlation networks
Despite the success of quantum mechanics in predicting the outcomes of experiments in many branches of physics, the foundations of the theory have remained subject of research and dispute. At the basis of this struggle ...
Nonmesonic weak decay of Hypemuclei, The
In single A hypernuclei, a A hyperon can occupy any orbital in the hypernucleus since it is free from the Pauli exclusion principle due to its additional quantum number strangeness. <br/><br/>Due to the Pauli blocking ...
Nontypeable Haemophilus influenzae: colonization, infection and biofilm formation
Haemophilus influenzae is an opportunistic pathogen that forms part of the human nasopharyngeal microbiota. This microorganism is classified into encapsulated and nonencapsulated or nontypeable (NTHi) isolates, depending ...
