1. Intrinsic tunneling spectroscopy of low-Tc cuprate superconductors : Pseudogap, fluctuations and electrical doping
Abstract : In this thesis, intrinsic tunneling and magnetic transport measurements of the cuprate superconductor Bi2+xSr2-yCuO6+δ (Bi-2201) are presented. The compound is characterized by a single-CuO2 plane, has a very low critical temperature Tc ~ 4K and a relatively low upper critical field Hc2 ~ 10T. READ MORE

2. Unraveling the cuprate superconductor phase diagram : Intrinsic tunneling spectroscopy and electrical doping
Abstract : High-temperature superconductors belong to the group of strongly correlated materials. In these compounds, complex repulsive electron interactions and a large number of degrees of freedom lead to a rich variety of states of matter. READ MORE

3. From exotic superconductivity to QCD and back again searching things in common
Abstract : This thesis is devoted largely to two new features which Particle Physics and Condensed Matter theory have in common. The first part of the thesis is a discussion of formation of phases precursory to the chiral phase transition in relativistic models with four-fermion interactions, considered as toy models for QCD.

4. Raman Scattering and Neutron Diffraction Studies of Manganites and Cuprates
Abstract : This thesis is devoted to experimental studies of two classes of strongly correlated transition metal oxides, namely cuprates and manganite perovskites. Manganites generally display complex phase diagrams, including the so-called colossal magnetoresistance effect. READ MORE

5. Fluctuating superconductivity and pair-density wave order in the cuprate superconductors
Abstract : High-temperature superconductors are some of nature’s most enigmatic materials. Besides carrying a supercurrent, these materials manifest a range of electronic and structural orders. READ MORE
