Cooper quartets and fractional vortices in frustrated Josephson junction dice arrays

This paper demonstrates through numerical simulations and tensor network techniques that frustrated Josephson junction dice arrays at one-third flux quantum frustration exhibit a superconductor-insulator transition characterized by half-vortex deconfinement and the emergence of a topologically protected 4e superconducting phase mediated by Cooper quartets.

Crossover from Rabi oscillations to adiabatic population switching in the Faraday optical control of quantum dot spins

This paper demonstrates that by manipulating the detuning beatnote in a Faraday geometry-driven unbalanced Λ\Lambda system, researchers can achieve a controlled crossover from Rabi oscillations to adiabatic population switching via Landau-Zener-Stückelberg interference, thereby establishing the oscillating Stark shift as a versatile mechanism for engineering spin dynamics and enabling simultaneous single-shot qubit readout and control.

Bulk and surface excitons in the van der Waals magnet CrSBr: Magneto-optical studies to 55 tesla

By subjecting few-layer CrSBr to magnetic fields up to 55 tesla, this study confirms the existence of distinct bulk and surface excitons through their differing magnetic field responses, specifically a reduced redshift and smaller diamagnetic shift observed in the lower-energy surface exciton resonance.

Quantum Hall effect in vacancy-engineered β\beta-Ag2_2Te

This paper demonstrates that *in-situ* vacancy engineering during molecular beam epitaxy enables the synthesis of high-mobility β\beta-Ag2_2Te thin films with dominant surface transport, allowing for the observation of a fully developed ν=1\nu=1 quantum Hall state and confirming massless Dirac dispersion without the need for external gating or lithography.

Effects of Electron Form Factor on Quasiparticle Interference in Twisted Bilayer Graphene

This paper demonstrates that quasiparticle interference (QPI) imaging in twisted bilayer graphene serves as a direct experimental probe for the electron form factor, revealing chiral interlayer interference patterns and validating topological constraints on Wannier orbitals through a combination of real-space tight-binding simulations and continuum model analysis.

Minimal d-Band Model for the Optical Susceptibility of Non-Centrosymmetric Monolayer Transition Metal Dichalcogenides

This paper proposes a minimal three-band model based on dd-orbital contributions to accurately reproduce the linear and quadratic optical susceptibilities of non-centrosymmetric monolayer transition metal dichalcogenides up to 2 eV above the band gap, offering a computationally efficient alternative to full $ab$ initio calculations for studying many-body effects.
