Pressure and strain tuning of the alternating bilayer-trilayer Ruddlesden-Popper nickelate: crystal and electronic structure

This study utilizes first-principles calculations to demonstrate that hydrostatic pressure and biaxial compressive strain both suppress octahedral tilts in the hybrid bilayer-trilayer nickelate La $_7$ Ni $_5$ O $_{17}$ to stabilize a tetragonal $C2/c$ structure, yet they induce distinct electronic behaviors by causing the trilayer $d_{z^2}$ band to cross the Fermi level under pressure while keeping it below the Fermi level under strain.

Stroboscopic detection of itinerant microwave photons

This paper proposes a novel scheme using cascaded Josephson-photonics devices to achieve highly efficient, near-projective stroboscopic detection of itinerant microwave single photons with low dark counts, potentially reaching near-unity efficiency through photon multiplication.

Tight-Binding Energy-Phase Calculation for Topological Josephson Junction Nanowire Architecture

This paper presents a numerical tight-binding calculation of the energy-phase relationship and bound state dynamics for Josephson junctions incorporating topological superconducting nanowires, aiming to inform the development of fault-tolerant qubits that mitigate decoherence in the NISQ era.

Quantum thermodynamic uncertainty relation and macroscopic superconducting coherence

This paper establishes that macroscopic superconducting coherence in hybrid normal-superconducting devices governs deviations from standard thermodynamic uncertainty relations in the subgap regime, leading to the derivation of a generalized quantum uncertainty bound for the Andreev regime that remains universally valid.

Artificial Transmission Line Synthesis Tailored for Traveling-Wave Parametric Processes

This paper establishes a unified theoretical framework for synthesizing artificial transmission lines tailored for traveling-wave parametric processes by integrating periodic structure theory and passive network synthesis, thereby revealing fundamental design constraints and enabling novel TWPA architectures such as kinetic inductance and ambidextrous Josephson-based amplifiers.

Thermally-controlled flux avalanche dynamics in bulk NbTi superconductor

This study presents the first direct visualization of flux avalanches in bulk NbTi superconductors, revealing that their propagation is governed by a thermally limited regime with significantly slower velocities (15–25 m/s) compared to thin films, driven by local heating and poor thermal coupling.

A Landau Theory for Pair Density Modulation in Fe(Te,Se) flakes

Motivated by recent STM observations of pair-density modulation (PDM) in FeTe $_{0.55}$ Se $_{0.45}$ flakes, this paper develops a Landau theory attributing the phenomenon to surface-induced glide symmetry breaking that stabilizes a hybridized order parameter, thereby suggesting local iron-site pairing driven by Hund's coupling and predicting a magnetic-field-induced reentrant triplet phase.

Cuprates, Pnictides and Sulfosalts: Lessons in Functional Materials

This paper utilizes the sulfosalt Murunskite as a structural and electronic bridge to compare cuprates and pnictides, proposing that while cuprate superconductivity arises from the scattering of mobile oxygen holes by localized copper holes, a similar mechanism in pnictides involves a light Fermi liquid scattering off a slow, nearly-antiferromagnetic one.

Microwave spin resonance in epitaxial thin films of spin liquid candidate TbInO3

This study employs coplanar superconducting resonators to probe magnetic excitations in epitaxial TbInO3 thin films, revealing extreme magnetic frustration down to 20 mK and elucidating the complex interplay of spin-orbit coupling, crystal fields, and improper ferroelectricity that shapes its quantum spin liquid candidate ground state.

Ferroaxial and nematic transitions in the charge density wave phase of 1T-TiSe $_2$

By utilizing symmetry-resolved elastoresistivity and elastocaloric measurements, this study resolves the controversy regarding the charge density wave in 1T-TiSe $_2$ by identifying it as a centrosymmetric ferroaxial state that precedes a distinct nematic transition, thereby reconciling conflicting surface-sensitive observations with bulk symmetry constraints.
