A guiding principle of my current research is the identification and description of mechanisms that increase substantially the critical temperature of a superconductor. The solution of this problem is intimately related to several problems of current interest in the condensed matter community.  My research group is  supported by three grants: EPSRC Career Acceleration Fellowship (2011-2016) and Fundação para a Ciência de Portugal (2011-2014) and a Marie Curie International Reintegration Grant (2010-2014).

SUPERCONDUCTIVITY IN NANO/HETERO STRUCTURES
 HOLOGRAPHY IN CONDENSED MATTER
Recent technological advances in both growth and measurement of nano/hetero structures have put the basis to study quantitatively nanoscale superconductivity. One particular area of interest is the identification of materialsphysical mechanisms and geometrical arrangements which lead to an enhancement of superconductivity in the nanoscale. Examples of current interest include copper oxides heterostructures, LAO/STO interfaces and granular conventional superconductors.  
The AdS/CFT correspondence, also referred to as the holographic principle, is arguably he most important theoretical development in high energy physics of the last decade. It conjectures that certain strongly coupled field theories are dual of weakly coupled gravity theories in a different dimension. The application of the holographic duality in condensed matter systems is rapidly emerging as a forefront research field. Problems of special interests are those in which some sort of universality is expected such far from equilibrium dynamics and phase transitions induced by disorder temperature or interactions.

It is now possible to control and measure the size and shape of a superconducting nanograin.  This paves the way for a quantitative understanding of nanoscale superconductivity. Figure from Nature Materials, 9, 550 (2010). Holographic techniqes are suitable to describe many aspects of strongly coupled systems such as he conductivity. Morever it can also be employed to study  finite size effects,  arxiv 1204.4189, or different types of phase transitions (see figure) Phys. Rev. D 81, 041901 (2010). 


NOVEL FORMS OF  SUPERCONDUCTIVITY
 INTERACTIONS, DISORDER AND  THERMALIZATION
Ultra cold gases are providing unparalled information about strongly interacting quantum matter. Motivated by these experimental advances this project aims to explore the role of Efimov physics in novel forms of superconductivity and its potential role to enhance superconductivity.
Disorder in condensed matter system is ubicuous. Recently it has also been possible to introduce disorder in cold atom settings. The main goal of this reasearch line is to achieve an quantitative understanding of the role of disorder and Anderson localization in interacting systems specially  in superconductors out of equilibrium or in materials in which the spin-orbit interaction is important.

Pauli principle has an important impact in an ensemble of trimers. However not much is known on its superconducting properties. Figure from  Phys. Rev. Lett. 106 (2011) 145301
It is not always possible to define a typical thermalization time! . Figure from Phys. Rev. E 85, 050102(R) (2012)
