Graphene is a member of the family of two-dimensional materials. Apart from the familiar spin degree of freedom, low-energy electrons in graphene have an additional degree of freedom: the valley, which plays the role of a pseudospin, implying that el

Quantum devices characterized by non-Hermitian topology are predicted to show highly robust and potentially useful properties, but realizing them has remained a daunting experimental task. This is because non-Hermiticity is often associated with gain

This work presents the study of phase transitions and electronic properties of two transition metal dichalcogenides: WTe2 and MoTe2. The relevance of those materials lies in its two metastable phases at ambient pressure and temperature, 1T’ and Td,

This thesis presents experimental studies performed with ultracold samples of atomic dysprosium. The electronic properties of dysprosium lead to a large magnetic moment, a large total angular momentum J=8 in the electronic ground state and a rich spe

The quantum Hall effect, is an effect which appears in the 2D gas when a field is applied, such as the material will become insulating, except on the edge. The transport will be on ballistic and chiral edge channels. This is these channels will be th

This thesis focuses on the intrinsic scattering of phonons by a general quantum degree of freedom, i.e. a fluctuating field Q with a priori completely general correlations, constrained only by unitarity and translational invariance. The scattering ra

In this thesis, we theoretically explore the propagation of light beams in two types of complex media where a non trivial refractive-index inhomogeneity shows up. The first one in a medium displaying spatial disorder in a plane transverse to the opti

Graphene exhibits a bidimensional electron gas directly exposed to vacuum, thus accessible by scanning tunneling microscopy (STM) and spectroscopy. In this PhD thesis we present a systematic STM spectroscopy study performed on high-quality graphene s
