Abstract Vortices in superconductors can help identify emergent phenomena but certain fundamental aspects of vortices, such as their entropy, remain poorly understood. Here, we study the vortex entropy in underdoped Bi2Sr2CaCu2O8+x by measuring both

Abstract The superconducting gap symmetry is crucial in understanding the underlying superconductivity mechanism. Angle-resolved photoemission spectroscopy (ARPES) has played a key role in determining the gap symmetry in unconventional superconductor

Abstract Charge-transfer excitations are of paramount importance for understanding the electronic structure of copper-oxide based high-temperature superconductors. In this study, we investigate the response of a Bi $$_2$$ 2 Sr $$_2$$ 2 CaCu $$_2$$ 2

Thermoelectric materials can recover electrical energy from waste heat and vice versa, which are of great significance in green energy harvesting and solid state refrigerator. The thermoelectric figure of merit (zT) quantifies the energy conversion e

Here, by using angle-resolved photoemission spectroscopy, we showed that Bi2−xCrxSe3 single crystals have a distinctly well-defined band structure with a large bulk band gap and undistorted topological surface states. These spectral features are un

Abstract Majorana bound states are putative collective excitations in solids that exhibit the self-conjugate property of Majorana fermions—they are their own antiparticles. In iron-based superconductors, zero-energy states in vortices have been rep

Abstract The ultra-quantum limit is achieved when a magnetic field confines an electron gas in its lowest spin-polarised Landau level. Here we show that in this limit, electron doped ZrTe5 shows a metal-insulator transition followed by a sign change

Understanding the rich electronic orders in cuprate superconductors provide insights into the mechanism of high-temperature superconductivity. Here, the authors report a distinct charge order with Little-Parks like resistance oscillations at magnetic

The pairing mechanism behind the Cooper pairs in unconventional superconductors has been debated since the discovery of the high-Tc cuprates. Here, using angle resolved photoemission spectroscopy data for Bi2212 applied to the Bethe-Salpeter equation

The underlying mechanism of iron-based superconductivity, the role of electron correlations, and the extent to which the behavior resembles those of the cuprates has been debated since their discovery. Here, using angle resolved photoemission spectro
