Competing and Intertwined Orders in Boson-Doped Mott Antiferromagnets

Using large-scale density matrix renormalization group simulations of the bosonic $t$ - $t'$ - $J$ model, this study reveals six distinct quantum phases—including pair density waves and phase-separated ferromagnetic domains—arising from the competition between doped holes and antiferromagnetic order, while proposing a concrete experimental realization in Rydberg tweezer arrays to explore these intertwined orders relevant to high- $T_c$ superconductivity.

A tractable framework for phase transitions in phase-fluctuating disordered 2D superconductors: applications to bilayer MoS $_2$ and disordered InO $_x$ thin films

This paper develops a self-consistent microscopic thermodynamic framework that unifies fermionic quasiparticles, Coulomb-regularized phase fluctuations, and BKT vortices to explain how disorder and carrier density drive the separation between the superconducting gap and transition temperature in 2D systems, successfully reproducing experimental results for bilayer MoS $_2$ and disordered InO $_x$ films.

Synthesizing Strong-Coupling Kohn-Luttinger Superconductivity in 2D Van der Waals materials

This study demonstrates through simulations and *ab initio* calculations that stacking two-dimensional van der Waals materials can induce a robust, high-temperature inter-layer s-wave superconductivity driven by a strong-coupling Kohn-Luttinger mechanism, where pairing attraction scales linearly with inter-layer repulsion rather than quadratically.

Superconducting States and Intertwined Orders in Metallic Altermagnets

This paper investigates multicomponent superconductivity in interacting $d$ -wave metallic altermagnets, revealing how distinct normal-state fluctuations—specifically nematic and spin current-loop modes—compete or cooperate to shape a rich phase diagram featuring nematic and chiral topological superconducting states.

Spectroscopic evidence of disorder-induced quantum phase transitions in monolayer Fe(Te,Se) superconductor

This study demonstrates that controllably introducing disorder via iron cluster deposition in monolayer Fe(Te,Se) drives a superconductor-insulator transition, revealing a disorder-induced quantum phase transition characterized by the evolution from superconducting to insulating U-shaped gaps attributed to localization-enhanced Cooper pair correlations.

Spin-polarized Andreev molecules and anomalous nonlocal Josephson effects in altermagnetic junctions

This paper demonstrates that weakly coupled altermagnetic Josephson junctions host spin-polarized Andreev molecules, which induce anomalous nonlocal Josephson effects including tunable phase transitions and a nonreciprocal diode effect, thereby establishing altermagnetism as a promising platform for nonlocal spin Josephson phenomena.

Systematic study of superconductivity in few-layer $T_d$ -MoTe $_2$

This paper presents a systematic study of few-layer $T_d$ -MoTe $_2$ that correlates superconducting properties with material parameters and band structure, revealing that highly hole-doped bilayer samples exhibit conventional phonon-mediated $s_{(++)}$ -wave pairing.

First-principles calculation of coherence length and penetration depth based on density functional theory for superconductors

This paper presents a parameter-free, first-principles framework based on superconducting density functional theory to simultaneously calculate the coherence length, penetration depth, and transition temperature of superconductors, successfully validating the method against experimental data and providing a microscopic explanation for the Uemura plot's empirical correlations.

Temperature-Dependent Dielectric Function of Tantalum Nitride Formed by Atomic Layer Deposition for Tunnel Barriers in Josephson Junctions

This study demonstrates that atomic layer deposition (ALD) of tantalum nitride (TaN) films yields thermally stable, insulating tunnel barriers with a band gap of 1.5–1.8 eV and uniform composition, making them a superior alternative to aluminum oxide for fabricating high-quality Josephson junctions in superconducting quantum circuits.
