Past achievements
 Gaugecovariant quasiclassic transport formalism for the superconducting state in the presence of spin interaction (including spinorbit and exchange interactions). See this arXiv paper. The generic theory has been developed during the winter 20132014, and several applications of the gaugecovarianttransport formalism can be found in the remaining of my works.
 Electric manipulation of the magnetization of a Josephson 2D bridge, when Zeeman and spinorbit effects conspire to create a coherent magnetoelectric coupling. See the demonstration of the existence of the magnetoelectric effect and the quasiclassic theory of the magnetoelectric manipulation. In collaboration with A.I. Buzdin (2009), I.V. Tokalty and F.S. Bergeret (2015).
 Generalisation of the Josephson relations when the superconducting condensate is mechanically displaced. See the theoretical prediction or the experimental verification of the predicted selfsustained oscillations. Theory in collaboration with Ya.M. Blanter (2011). Experiments performed by S. Etaki, H. Yamaguchi and H. van der Zant (20102013).
 Decoherence mechanism of the topological wires hosting some Majorana modes, with peculiar emphasis on the propagation of a quantum error along the topological circuit. For a clean pwave superconductor, the qubitflip error propagates at the Fermi velocity, somehow a problem for the topological protection. See this arXiv paper. In collaboration with F. Hassler (2013).
 Fluctuations description of the inhomogeneous superconducting state, giving smoking gun experiments possibilities (radically different exponents of the Gaussian fluctuations than for the homogeneous case). See the letter and the long arXiv versions of the work. In collaboration with J. Cayssol and A.I. Buzdin (20062009).
