School of Physical Sciences



I received my Physics education at the University of Salamanca in my native Spain (Licenciado, 1992-1997) and at the University of Bristol (PhD, 1997-2001) where I completed a thesis on unconventional superconductors under the supervision of the late Balazs L. Gyorffy. I then moved to Brazil, where I held a postdoctoral position in the University of Sao Paulo at Sao Carlos (2002) and worked with Luiz Oliveira and Klaus Capelle on proximity effects in superconductors and with Vivaldo L. Campo on electronic statates in small-world networks.

One year later I moved back to the U.K. to take up a research fellowship at the University of Birmingham (2003-2005). In Birmingham I started new collaborations with my supervisor Andy Schofield, with Chris Hooley and, later, with Sam Carr. During this time my research interests broadened further to include quantum liquid crystal states and the Pomeranchuk instability and ultra-cold atoms. After Birmingham, I took up the Atlas Research Fellowship in Condensed Matter Theory at the ISIS Facility in the STFC Rutherford Appleton Laboratory, in Harwell, and at St. Catherine's College, Oxford (2005-2010). At RAL I developed a keen interest in extending, through my theoretical research, the capabilities of large-scale facilities employed in condensed matter research, including the muon and neutron instruments at the ISIS spallation neutron source.

My current interests include broken time-reversal symmetry in centrosymmetric and non-centrosymmetric superconductors, topological defects and excitations in condensed matter and experimental signatures of quantum entanglement in magnetic materials.

During my career I have been an Individual Marie Curie Fellow; a Fellow of St. Catherine’s College, Oxford; and an honorary research associate of the London Centre for Nanotechnology. I also chaired SEPnet's Atomic and Condensed Matter research theme (07/2010-02/2012) and I am a founding member of the Hubbard Theory Consortium.

Research Interests

Dr. Quintanilla is a theorist working on quantum condensed matter and materials physics. His main interests are in the area of strongly-correlated quantum matter and include unconventional superconductors, frustrated and quantum magnets, and other materials with strongly-correlated electrons. Past interests also include ultra-cold gases and complex networks. More information about Dr. Quintanilla's research interestes can be obtained in his research group's blog:

Office hours for autumn term 2017/2018:

  • Monday 9:30-10:30
  • Friday 9:30-10:30

except Week 3 (no office hours) and Week 4 (office hours extended until 11:30 both Monday and Friday).

I am the convenor of a 4th-year module on "Superconductivity and Magnetism" (PH752) and a 2nd-year module on "Quantum Mechanics" (PH502). I also teach half of the the 1st year module "Electricity and Light" (PH322) and I am one of the lecturers in the biannual "SEPnet GRADnet workshop on strong correlations". Finally, I regularly supervise physics undergraduate, master and PhD research projects. More information on student research opportunities within my group can be found here:
