Electronic nematic materials are characterized by a lowered symmetry of the electronic system compared to the underlying lattice, in analogy to the directional alignment without translational order in nematic liquid crystals. Such nematic phases appear in the copper- and iron-based high-temperature superconductors, and their role in establishing superconductivity remains an open question. Nematicity may take an active part, cooperating or competing with superconductivity, or may appear… 
Enhanced Hybridization Sets the Stage for Electronic Nematicity in CeRhIn_{5}.
TLDR
It is argued that the nematic behavior observed in this prototypical heavy-fermion material is of electronic origin, and is driven by the hybridization between 4f and conduction electrons which carries the f-electron anisotropy to the Fermi surface.
Emerging symmetric strain response and weakening nematic fluctuations in strongly hole-doped iron-based superconductors
TLDR
By decomposing the strain response into the appropriate symmetry channels, it is demonstrated the emergence of a giant in-plane symmetric contribution, associated with the growth of both strong electronic correlations and the sensitivity of these correlations to strain.
Electrical resistivity across a nematic quantum critical point
TLDR
The observation of T-linear resistivity at a nematic critical point raises the question of whether strong nematic fluctuations play a part in the transport properties of other ‘strange metals’, in which T- linear resistivity is observed over an extended regime in their respective phase diagrams.

ABSTRACT Despite more than ten years of extensive research, the superconducting mechanism of iron-based superconductors (FeSCs) is still an open question. Generally, the high-temperature

We consider the nuclear spin-lattice relaxation rate 1/T1 in superconductors with accidental nodes, i.e., zeros of the order parameter that are not enforced by its symmetries. Such nodes in the

It is demonstrated that superconductivity competes with the emerging nematicity, and unequivocally establishes orbital degrees of freedom as driving the nematic order.

TLDR
Measurement of the divergent nematic susceptibility of the iron pnictide superconductor Ba(Fe1−xCox)2As2 distinguishes an electronic nematic phase transition from a simple ferroelastic distortion, and measurements indicate an Electronic nematic quantum phase transition near the composition with optimal superconducting transition temperature.

TLDR
Evidence is shown for a phase transition to a state akin to a density wave (DW) under high magnetic fields (>27 T) in high-quality single crystal microstructures of CeRhIn₅, yet remarkably thermodynamic measurements suggest that the phase transition involves only small portions of the Fermi surface.
