This paper presents a theoretical model demonstrating that the rigidity of encapsulation interfaces significantly influences lattice relaxation in twisted bilayers, specifically raising the critical twist angle for the transition between weak and strong relaxation regimes and enabling better alignment with experimental data.
First-principles calculations reveal that monolayer TiI possesses an unconventional bright exciton ground state, driven by spin-orbit-induced band alignment and weak exchange interactions, which remains stable under strain and extends to trion states, offering significant potential for applications requiring fast radiative recombination.
This paper investigates the topological electronic properties of the crystal, revealing that it is a spinless Weyl semimetal hosting Weyl nodes with both conventional () and higher () chiralities that give rise to topologically protected Fermi arc surface states connecting nodes of opposite chirality.
This paper demonstrates that periodic honeycomb networks of ballistic conducting channels generically host robust, exact flat bands spanning the entire Brillouin zone, which arise from local symmetry and lattice translations, persist regardless of vertex scattering or transverse modes, and maintain a universal ratio with dispersive bands.
This paper presents a direct laser writing technique that fabricates high aspect ratio, optically accessible nanochannels between diamond films and glass substrates, demonstrating their ability to spontaneously fill with water via capillary action while maintaining mechanical stability and clog resistance for advanced nanofluidic applications.
This paper investigates two-port scattering in non-Hermitian PT-symmetric and non-reciprocal dimer models, demonstrating that while standard unitarity fails for right scattering states, biorthogonality restores generalized unitarity and reveals distinct physical mechanisms—complex eigenvalues and eigenstate non-orthogonality—that enhance transport probabilities.
This paper theoretically demonstrates that spin-valley-locked tunneling in transition metal dichalcogenide/ferromagnet hybrids driven by the spin Seebeck effect generates a valley-polarized spin current exhibiting pronounced quantum oscillations, which serve as a distinct experimental signature of quantized valley states.
This paper demonstrates that periodically driven quantum rotors serve as a versatile platform for realizing anomalous multi-gap topological phases, characterized by non-Abelian band braiding that stabilizes nodal lines and gives rise to a unique out-of-equilibrium Dirac string phase with distinct edge states.
This paper extends the Landauer-Büttiker formula to open quantum systems with gain or loss using the Lindblad-Keldysh formalism, revealing novel transport phenomena such as current generation from symmetry breaking or disorder, and the restoration of the Wiedemann-Franz law beyond the energy band.
This study experimentally demonstrates that while gap engineering in 3D transmon qubits reduces quasiparticle burst detection rates by a factor of five, the limited improvement compared to theoretical expectations is attributed to the slow thermalization of phonons following ionizing radiation events.
