Affective Sustainability. The Creation and Transmission of Affect through an Educative Process: An Instrument for the Construction of more Sustainable Citizens

Although for many years the debate on sustainability has focused on the generation of critical thinking based on the dynamic balance between the economic, social and environmental spheres, in the following text we propose to elaborate on the use of a eminently human condition, such as the capacity to love and create an emotional attachment, whether with our environment or our fellow men, as an initiator and main force for change to the building a more sustainable model of development. To do so we shall begin from the concept coined by Adriana Bisquert in the 90s, that is A ective sustainability, by analyzing it, delving into its possible definitions by means of the development of the project for Environmental Education and Development called “Educating for a more sustainable citizenship” undertaken by the Spanish NGO (non-governmental organization) or ITACA Ambiente Elegido, and developed in the locality of Paterna de Rivera, Cádiz (Spain). This is a practical and real example, which is used to establish a work educational methodology that enables us to consider this concept as the real basis for an exportable and replicable work in a painstaking search for the creation of a more sustainable city

Una manera posible de naturalizar el alma humana

One of the most basic linguistic principles (or parameters, according to some) is used to point to a likely necessary (though, probably, not sufficient) condition of human uniqueness (i.e. being able to speak, communicate complex messages, have religious feelings, indulge in art and humour, and so on) which has been conceptualised either as the fact that we have human souls, in religious contexts, or human minds, in other contexts

Nonlinear fiber gyroscope for quantum metrology

We examine the performance of a nonlinear fiber gyroscope for improved signal detection beating the quantum limits of its linear counterparts. The performance is examined when the nonlinear gyroscope is illuminated by practical field states, such as coherent and quadrature squeezed states. This is compared with the case of more ideal probes such as photon-number states.Comment: 8 pages, 1 figur

A simple method to construct Flat Band lattices

We develop a simple and general method to construct arbitrary Flat Band lattices. We identify the basic ingredients behind zero-dispersion bands and develop a method to construct extended lattices based on a consecutive repetition of a given mini-array. The number of degenerated localized states is defined by the number of connected mini-arrays times the number of modes preserving the symmetry at a given connector site. In this way, we create one or more (depending on the lattice geometry) complete degenerated Flat Bands for quasi-one and two-dimensional systems. We probe our method by studying several examples, and discuss the effect of additional interactions like anisotropy or nonlinearity. At the end, we test our method by studying numerically a ribbon lattice using a continuous description.Comment: 11 pages, 11 figure

Many-Body Coherent Destruction of Tunneling

A new route to coherent destruction of tunneling is established by considering a monochromatic fast modulation of the self-interaction strength of a many-boson system. The modulation can be tuned such that only an arbitrarily, a priori prescribed number of particles are allowed to tunnel. The associated tunneling dynamics is sensitive to the odd or even nature of the number of bosons.Comment: 4 pages, 3 figures, accepted for publication in Phys. Rev. Let

Three-dimensional localized-delocalized Anderson transition in the time domain

Systems which can spontaneously reveal periodic evolution are dubbed time crystals. This is in analogy with space crystals that display periodic behavior in configuration space. While space crystals are modelled with the help of space periodic potentials, crystalline phenomena in time can be modelled by periodically driven systems. Disorder in the periodic driving can lead to Anderson localization in time: the probability for detecting a system at a fixed point of configuration space becomes exponentially localized around a certain moment in time. We here show that a three-dimensional system exposed to a properly disordered pseudo-periodic driving may display a localized-delocalized Anderson transition in the time domain, in strong analogy with the usual three-dimensional Anderson transition in disordered systems. Such a transition could be experimentally observed with ultra-cold atomic gases.Comment: version accepted for publication in Phys. Rev. Lett., supplemental material include
