Entanglement (1+2) QED in a double layer of Dirac Materials

This paper investigates how momentum-space entanglement between Dirac quasiparticles in a double-layer honeycomb lattice is mediated by a planar electromagnetic cavity, demonstrating that while perturbative interactions yield low entropy, self-energy dressing can drive a crossover to a high-entropy regime suitable for generating Bell-like states.

Three-dimensional topological ferroelectrics

The paper predicts and demonstrates that the newly identified γ\gamma-phase bismuth monohalides (Bi4Br4\text{Bi}_4\text{Br}_4 and Bi4I4\text{Bi}_4\text{I}_4) are ideal three-dimensional topological ferroelectric insulators that feature switchable polarization and robust spin-resolved topology, offering a promising platform for field-controlled spintronic devices.

Electrically detected magnetic resonance of 75^{75}As magnetic clock transitions in silicon

This paper demonstrates the observation of magnetic clock transitions in near-surface 75^{75}As spins in silicon using low-field continuous-wave electrically detected magnetic resonance (EDMR), establishing the technique as a sensitive method for studying decoherence suppression in silicon-based quantum devices.
