TL;DR: Mid-infrared femtosecond pulses are used to enable coherent transport between the copper oxide planes of a cuprate superconductor, and an upper limit for the time scale needed to form the superconducting phase is estimated to be 1 to 2 picoseconds, which places stringent new constraints on the understanding of stripe order and its relation to superconductivity.

TL;DR: In this article, the authors present ultra-high energy-resolution spectroscopic imaging (SI)-STM to clarify the nature of the vortex bound states in Fe(Se,Te), and show that some vortices host the Majorana bound states but others do not.

TL;DR: A comparative study of thermoelectric transport in the cuprates YBCO and La1.8−xEu0.2SrxCuO4 (Eu-LSCO) is used to show that the two materials exhibit the same process of Fermi-surface reconstruction as a function of temperature and doping.

TL;DR: It is reported that in some of these materials the large Nernst signal is in fact the result of stripe order, a form of spin/charge modulation that causes a reconstruction of the Fermi surface.

TL;DR: In this paper, it was shown that a large negative κxy signal is a property of the pseudogap phase, appearing at its critical hole doping, p*, and that this signal grows as the system becomes increasingly insulating electrically, it cannot be attributed to conventional mobile charge carriers.
