This paper proposes and experimentally demonstrates a non-Abelian Hatano-Nelson model in electric circuits featuring a nonreciprocal U(2) gauge field, which induces unique Hopf-link-shaped energy braiding and a bipolar skin effect, thereby expanding the scope of experimental non-Hermitian physics.
This paper demonstrates that incorporating trigonal warping effects into AB-stacked bilayer graphene enables a low-field metal-insulator transition at approximately 10 T, a significant reduction from previously predicted requirements, by utilizing a transverse electric field to open a gap that is subsequently closed by a relatively small in-plane magnetic field.
This paper presents a universal framework and numerical optimization strategies for a measurement-based quantum thermal machine using a coupled two-level Ising system, demonstrating that such engines can achieve high efficiency and robustness against errors while being directly implementable with current quantum technologies.
This study introduces five tight-binding models of polyacene chains to demonstrate that while $cis$- and $trans$-polyacene share identical band structures, they exhibit opposite topological characters, with $trans$-polyacene being nontrivial and $cis$-polyacene being trivial, while two of three modified polyacene structures also display exotic topological behavior.
This paper demonstrates that the anomalous thermoelectric Hall response of interacting 2D massive Dirac fermions remains non-zero at zero temperature even after subtracting magnetization currents, a surprising result attributed to the inevitable manifestation of locality violation in the infrared physics of quantized field theories.
This paper presents a non-contact, frequency-domain photo-reflectance technique that simultaneously characterizes carrier and phonon transport in semiconductors without sample pretreatment, enabling the accurate extraction of temperature-dependent electrical and thermal coefficients for various materials.
This paper introduces a theoretical framework that maps arbitrarily stacked graphene bilayers with specific interplanar distances onto an equivalence class of magic-angle twisted bilayer graphene, enabling efficient ab initio simulations of their exotic electronic properties using computationally manageable supercell sizes.
This paper demonstrates that while quenched disorder can induce a transition from a non-Hermitian skin effect to many-body localization in systems conserving only U(1) charge, the skin effect remains robust against arbitrary disorder in systems with conserved dipole or higher multipole moments, ensuring delocalization regardless of disorder strength.
This paper theoretically demonstrates that the spin relaxation lifetime of an Andreev spin qubit can be significantly enhanced by coupling it to a transmon circuit, where the Franck-Condon blockade suppresses spin flips by requiring the simultaneous excitation of multiple plasmons.
This study demonstrates that strong uniaxial anisotropy in iron films enables an anomalous inverse orbital Hall effect, where orbital dynamics mediated by high orbital Hall conductivity facilitate efficient orbital-to-charge conversion in out-of-plane configurations, offering new avenues for controlling spin and orbital currents in orbitronics devices.
