Quaternionic superconductivity with a single-field Bogoliubov-de Gennes--Ginzburg-Landau framework and charge-4e couplings

This paper establishes a compact quaternionic field theory framework for spinful superconductivity that unifies singlet and triplet pairing into a single field, enabling the analytical derivation and numerical verification of charge-4e signatures, including vestigial order criteria, fractional flux vortices, and dominant second-harmonic Josephson effects.

Metal hydrides achieve high-Tc superconductivity at low pressure by mimicking high-pressure H3S chemical bonding

This study proposes a new paradigm for achieving high-temperature superconductivity at low pressures in metal hydrides by mimicking the bonding characteristics of high-pressure H3S, exemplified by the Li3CuH4 compound which combines a covalent Cu-H framework for enhanced electron-phonon coupling with an ionic Li3H lattice for structural stability.

Quarkyonic matter and hadron-quark crossover from an ultracold atom perspective

This paper proposes a field-theoretical framework analogous to the BEC-BCS crossover in ultracold atoms to explain the hadron-quark crossover in dense matter, demonstrating that a tripling fluctuation effect can simultaneously account for the observed peak in the speed of sound and the baryon momentum-shell structure characteristic of quarkyonic matter.

Reversible tuning of magnetic order and intrinsic superconductivity in strained FeTe thin films via stoichiometry control

This study demonstrates that precise stoichiometric control to reduce interstitial iron impurities in strained FeTe thin films reversibly suppresses long-range antiferromagnetic order and induces intrinsic superconductivity at approximately 10 K without relying on complex oxygen incorporation or interfacial effects.
