Superconductivity is a fascinating state of matter where materials conduct electricity without any resistance, often defying our everyday expectations of how energy behaves. Researchers in this field explore the quantum mechanics behind these phenomena, seeking new materials that can operate at higher temperatures or under more practical conditions. This work holds the promise of revolutionizing everything from power grids to medical imaging devices, making the invisible world of quantum physics feel increasingly tangible and useful.

This paper reports the achievement of a record ambient-pressure superconducting transition temperature of 151 K in HgBa2Ca2Cu3O8+{\delta} by utilizing a novel pressure-quench protocol to stabilize pressure-induced superconducting states at ambient conditions.
Using optical pump-THz probe spectroscopy and Time-dependent Ginzburg-Landau simulations, researchers directly observed a non-equilibrium analog of critical slowing-down in NbN, where the superconductivity quenching time significantly lengthens near the condensation energy due to the flattening of the free energy landscape at the dynamical phase transition boundary.
This review summarizes recent advances in using scanning tunneling microscopy and spectroscopy to characterize two-dimensional unconventional superconductors, with a focus on high-temperature superconducting planes, pair-density waves, and topological superconductivity in both artificial heterostructures and intrinsic materials.
This paper analyzes pairing instabilities in altermagnetic metals on a square lattice, revealing that attractive nearest-neighbor interactions induce a finite-momentum Fulde--Ferrell--Larkin--Ovchinnikov (FFLO) superconducting phase characterized by a multi-component order parameter with mixed singlet-triplet parity, while triplet pairing between identical spins remains unfavorable at weak coupling.
This study reports the synthesis of locally noncentrosymmetric CeCoGe single crystals exhibiting a heavy-fermion ground state near a putative quantum critical point, while attributing the absence of superconductivity down to 20 mK to strong random potential scattering caused by intrinsic Co vacancies that can be controlled through growth stoichiometry.
This paper reports the experimental realization of a low-frequency transmon qubit that achieves a 100-fold suppression of charge-induced errors through Cooper-pair parity protection, enabling coherent control and single-shot readout while identifying flux noise as the primary remaining limitation to coherence.
This study demonstrates that in electron-doped cuprates, the thermal Hall conductivity arises from competing contributions of electrons and phonons, where the latter's negative signal persists across doping levels and suggests a fundamental link to antiferromagnetic correlations within the pseudogap phase.
This study theoretically proposes that resonant optical excitation of infrared-active lattice vibrations can induce nonlinear phononics to straighten the interlayer Ni-O-Ni bond angle in the bilayer nickelate LaNiO, offering a light-based alternative to pressure for controlling its crystal structure toward superconductivity.
This paper investigates universal thermalization induced by Trotterization in the reduced-BCS model, revealing a distinct "Trotter transition" at a critical time step that separates weakly chaotic dynamics from a regime of short temporal correlations characterized by specific scaling laws.
This paper demonstrates that spin-polarized supercurrents can electrically control magnetic interactions in spin lattices and tune magnon gaps in antiferromagnetic and altermagnetic insulators by making spin-spin coupling dependent on absolute spatial position, thereby enabling dissipation-free manipulation of non-collinear ground states and spin Hamiltonians.
