Complex Lattice and Charge Inhomogeneity Favoring Quantum Coherence in High-Temperature Superconductors

“…Iron-based superconductors have provided a key laboratory showing exotic superconducting phases characterized by inhomogeneity, nematic phases and multiple gaps [64][65][66][67][68][69]. The physics of the BCS-BEC crossover in quantum condensates in particular real space or k space spots widely studied in ultracold gases is now emerging as a generic feature in multiple condensates superconductors [70][71][72][73][74][75][76]. Understanding the emergence of novel spin-orbital phases [77] is now recognized to be a key ingredient for understanding high temperature superconductors and the advances in this field are now pushing the developments of spintronics and new quantum electronics [78][79][80][81][82][83].…”
