Superconductivity (SC) arises when electrons form Cooper pairs that move collectively without resistance. In the weak-coupling regime, this pairing is described by the Bardeen-Cooper-Schrieffer (BCS) theory, where electrons form weakly bound, overlapping Cooper pairs. In the opposite, strong-coupling limit, electrons form tightly bound bosonic pairs that undergo Bose–Einstein condensation (BEC). The smooth evolution between these two regimes—the BCS-BEC crossover—has been extensively studied in

RIKEN, Hirosawa 2–1, Wako, 351–0198, Japan. Quantum spin liquids (QSLs)—exotic magnetic states where electron spins remain disordered even at absolute zero—have long fascinated physicists for their rich entanglement and potential to host exotic quasiparticles [27,28,29]. Yet, the challenge has always been in stabilizing and probing such states in real materials. Molecular solids offer a clean platform with two-dimensional triangular lattices, which can be an ideal system to host QSLs. Two candi

Dark energy evolution: new insights from DESI by Shadab Alam The accelerating expansion of our universe, attributed to dark energy, has been a cornerstone of modern cosmology since its discovery in 1999. Recent findings from the Dark Energy Spectroscopic Instrument (DESI) may significantly transform our understanding of cosmic acceleration [1, 2]. In this article, we explore the implications of these new measurements and their potential to reshape fundamental physics. 1.1 The journey from a sta

1 Research highlights on plasma-based acceleration at IHEP by Dazhang Li, Wei Lu and Jie Gao Plasma-based acceleration (PBA) can sustain an accelerating gradient on the order of GV/cm, which is over three orders of magnitude higher than that achievable with conventional RF cavities [1]. Upon full development, this technology promises to substantially mitigate the current challenges associated with the excessive size and cost of high-energy accelerators and colliders. The Institute of High Energ
