Nanoscale Materials

Most states or phases of condensed matter can be described by local order parameters and the associated broken symmetries. However, since the quantum Hall Effect state gives the first useful example of topological states of matter which have topological quantum numbers different from ordinary states of matter and are described in the low energy limit by topological field theories. Mathematically, the integral of the curvature of Berry’s phase gauge field defined over the magnetic first Brillouin zone was shown to be a topological invariant defined by the first Chern number, which is physically measured as the quanta of the Hall conductance. This is the starting of a new form of working with materials as have shown the Nobel prize given in 2014 to this subject.

Insulators in 1+1 or 1+2 dimensions can also have unique topological effects. Solitons in charge-density wave insulators can have fractional charge or spin-charge separation open surprising new possibilities to these new materials. The electric polarization P of these insulators can be expressed in terms of the integral of Berry’s phase gauge field in momentum space and it is connected with thermal properties through thermoelectricity or topological superconductors which is still not well known, although experimentally starts to be quite well determined. Therefore, it is an open opportunity to theoreticians as us.


Development of new techniques to operationally receive, process and distribute satellite data and products. Within this scheme, our group manages the L-Band satellite receiving station which provides the Caribbean and Gulf of Mexico Coast Watch node with satellite telemetry. The products are distributed in near real time globally and free of charge to scientists and the general public.

There is a growing interest in the role of climate change in driving the spread of waterborne infectious diseases, such as those caused by bacterial pathogens. One particular group of pathogenic bacteria – vibrios – are a globally important cause of diseases in humans and aquatic animals. These Gram-negative bacteria, including the species Vibrio vulnificus, Vibrio parahaemolyticus and Vibrio cholerae, grow in warm low-salinity waters, and their abundance in the natural environment mirrors ambient environmental temperatures. In a rapidly warming marine environment, there are greater numbers of human infections, and most notablyoutbreaks linked to extreme weather events such as heatwaves. Because the growth of pathogenic vibrios in the natural environment is largely dictated by temperature, we work on the premise that this group of pathogens represents an important and tangible barometer of climate change in marine systems. Our work assesses the impacts of ocean warming on this group of bacteria and their associated diseases, and proposes advanced strategies to improve our understanding of these emerging waterborne diseases through the integration of microbiological, genomic, epidemiological, climatic, and ocean sciences. The outputs are models which are aimed to predict the link genomic epidemiology of waterborne  pathogens and marine environmental information within an scalable computation framework.

Our group has participated in the development of new products oriented to better understand the dynamics and biochemical processes in the ocean. Some of the products are related to ocean acidification, and estimate the parameters of the seawater carbonate system, such as pH, alkalinity and partial pressure CO2 in seawater. They also have been updated to improve robustness and reduce latency.
 We provide monthly  and daily global chlor_a climatologies, which have
 been created from MODIS/Aqua, MODIS/Terra and S-NPP/VIIRS data. They
 are being used  to develop and implement new indicators in conjunction with other parameters.

Energy and Sustainability

In the near future, around 75% of the world population will live in urban areas. We are consuming more resources than are available on Earth and we need to apply strategies and processes of sustainability and efficiency, especially in urban areas so that they have a greater impact. Our interest focuses on sustainability and energy efficiency, integrated planning and the design of data structures for decision-making at various scales applied to energy infrastructure, mobility, urban waste and building, preferably.

As a transition towards a more sustainable society in the near future, we need to innovate in order to obtain more efficient products, infrastructures and services based on the consumption of fuels or less polluting energies than those currently used on a massive scale.
Mobility to Gas Natural is a reality that is being developed worldwide in an accelerated way, innovating in all the elements of the logistics chain. Electric mobility promises an exciting future. Our interest is focused on the realization of studies and models for the implementation and monitoring of infrastructures and services of the Gas Natural logistics chain.

Strategic Programme

Research activities to collaborate with our strategic patners in current projects, define future challenges, objectives, projects activities and funding strategies.

Research activities to make our research group more competitive by improving our organization, competences and intensifying collaboration and internationalization.

Technological developments

The outcomes of our work are distributed through an interoperable scheme involving ERDDAP, THREDDS and Ocean Viewer servers, currently running at NOAA facilities in the United States. Ocean Viewer represents an effort to improve the visualization and access to in situ, satellite and model data hosted in-house or even in external servers.

We have implemented an architecture that allows, in a efficient and operational environment, generate daily vibrio risk fields using data from satellites and models. Monthly vibrio risk fields are being created from the daily estimates. The NetCDF files contain the average vibrio risk as well as the maximum risk values.
The University of Bath, CEFAS  and the ECDC are collaborators in this effort.

Software tools at corporative scale to monitoring and supervising electric and heat consumption in buildings. software tools allow monitoring and supervision of several buildings and technical facilities simultaneously. Define the data and signals to be monitored, their frequency and how they will be stored. The tools allow to control certain elements of technical installations, define and manage alarms and visualize in real time the facilities to manage them in a more efficient way. We collaborate with researchers of the CITIUS, an information technology Research Centre, in developing these tools.
