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
