The recent Nobel Prize in Physics awarded to John M. Kosterlitz, David J. Thouless and Duncan Haldane confirms the relevance of the research being done at the LBTS Research Group. Also reinforced is the interest of their doctorate and master programs. The prize recognizes the significance of the studies on reduced-dimensionality materials (such as for instance the studies on the vortex-antivortex coupling in twodimensional systems specially addressed by Kosterlitz and Thouless).

Among the research works authored by some of the members of LBTS on the physics of vortices and antivortices, notable mentions are, e.g., the reference C. Carballeira et al., Phys. Rev. Lett. 95, 237003 (2005), that was chosen for the cover page of the prestigious journal Physical Review Letters, published by the American Physcial Society. Also the recent A. Ramos-Álvarez et al. Phys. Rev. Lett. 95, 139701 (2015) that comments on the related twodimensional behaviour of the new Fe-based superconducting materials.

Also noticiable in this respect is the doctoral thesis of N. Cotón in 2013, that presents one of the few experimental observations of the famous "Kosterlitz-Thouless transition". To achieve that feat, Cotón was able to grow thin films of specially high quality, and also performed measurements with the high-precision quantum-interference magnetometer available at the LBTS. The thesis is available in this link.

The research of the LBTS group in these interesting physical phenomena in reduced-dimensionalty systems remains fully active, and in fact it promises relevant results in the near future. This is confirmed, for instance, by the masther thesis done at LBTS by D. Faílde, with maximum qualification for the master in physics of the USC in the academic course 2015/2016; this work presents a novel analysis of twodimensional systems coupled among them, and the ensuing collective Kosterlitz-Thouless transition.

The LBTS laboratory is a partner of the ENERMAT transnational network
