Tuning Thermal Conductivity and Electron-Phonon Interactions in Carbon and Boron Nitride Moiré Diamanes via Twist Angle Manipulation

This study demonstrates that increasing the interlayer twist angle in carbon and boron nitride Moiré diamanes significantly reduces in-plane lattice thermal conductivity and enhances band gap renormalization due to structural disorder and quantum nuclear effects, thereby offering a viable strategy for tuning their thermal and electronic properties for advanced applications.

Fibonacci Waveguide Quantum Electrodynamics

This paper demonstrates that waveguide quantum electrodynamics in aperiodic Fibonacci photonic arrays enables decoherence-free, coherent interactions between quantum emitters by engineering atom-photon bound states that inherit the deterministic complexity and multifractal properties of the underlying Fibonacci-Lucas structure.

Non-Hermitian skin effect and electronic nonlocal transport

This paper demonstrates that the non-Hermitian skin effect in a Rashba nanowire coupled to a ferromagnetic lead can be detected through nonreciprocal nonlocal conductance, offering a new transport spectroscopy method to probe non-Hermitian phenomena and explaining the parameter-space shifts of exceptional points under open boundary conditions.

One-dimensional topology and topolectrics of nonsymmorphic Kramers degenerate systems

This paper establishes a theoretical framework for one-dimensional nonsymmorphic Kramers degenerate systems with $\mathbb{Z}_2$ and $\mathbb{Z}_4$ topological classifications, extends winding-number invariants to these four-band models, and validates their topological phases and robust zero-energy modes through proposed topolectric circuit realizations and disorder analysis.

Ultrastrong magnon-photon coupling in superconductor/antiferromagnet/superconductor heterostructures at terahertz frequencies

This paper predicts that superconductor/antiferromagnet/superconductor heterostructures enable ultrastrong magnon-photon coupling at terahertz frequencies, where magnetic fields tune the interaction between one or both magnon modes and photons to create highly tunable magnon-polaritons with group velocities reaching several tenths of the speed of light.

Orbital Hall effect from orbital magnetic moments of Bloch states: the role of a new correction term

This paper presents a rigorous derivation of orbital magnetic moment matrix elements for Bloch states by incorporating a previously omitted Berry connection term, revealing two new gauge-covariant corrections that significantly reduce the orbital Hall conductivity in bilayer van der Waals materials.

Second-Harmonic Magnetoacoustic Ultrasound from Magnetic Nanoparticles under Radiofrequency Electromagnetic Fields

This study demonstrates that magnetic nanoparticles generate second-harmonic magnetoacoustic ultrasound under radiofrequency electromagnetic fields without thermal effects, a phenomenon enhanced by magnetic alignment that suggests a non-thermal mechanism for cell damage and offers new potential for in vivo theragnostic applications.

Topological transition induced by selective random defects on a honeycomb lattice

This study demonstrates that selective random defects on a honeycomb lattice can induce topological transitions or smoothly connect topological phases by modulating hopping amplitudes, offering a new strategy for controlling the spectral and topological properties of electronic systems.

Growth driven phase transitions in Zinc Oxide nanoparticles through machine-learning assisted simulations

This study reveals that while the body-centered tetragonal phase is thermodynamically stable for small zinc oxide nanoparticles, the atom-by-atom deposition process drives a phase transition to the more stable wurtzite structure through a specific ion redistribution that compensates for emerging polar facets.

Symmetries of excitons

This paper establishes a comprehensive group-theory framework for assigning symmetry labels and total crystal angular momentum to excitonic states, enabling the derivation of selection rules, conservation laws, and enhanced computational efficiency for the Bethe-Salpeter equation, as demonstrated through applications to LiF, monolayer MoSe2, and bulk hBN.
