Layer-Resolved Topological Metals in the Bilayer Lieb Lattice

This paper identifies a novel time-reversal-invariant topological metallic phase in a bilayer Lieb lattice characterized by a quantized layer-resolved pseudo-spin Chern number, where specific orbital-angular-momentum-dependent couplings tune the system between semimetallic and metallic regimes while preserving distinct, asymmetric edge states that can be selectively manipulated via interlayer and intralayer interactions.

Extended Landau--Lifshitz equation for nanomagnets: a path-integral derivation of surface-induced magnetization nutation

This paper derives an extended Landau-Lifshitz equation for nanomagnets with surface anisotropy using a spin coherent-state path integral formalism, demonstrating that eliminating fast transverse spin fluctuations leads to surface-induced magnetization nutation and renormalized damping effects that are experimentally measurable via ferromagnetic resonance.

Theory of phonon-induced spin relaxation in a structured phononic reservoir

This paper develops a comprehensive theory of electron spin relaxation in structured phononic reservoirs, such as quantum dots in phononic waveguides, revealing that while relaxation rates can be significantly enhanced compared to bulk materials, they can also be suppressed by orders of magnitude due to phononic bandgaps and symmetry selection rules, with complex non-Markovian dynamics emerging near van Hove singularities.
