This paper identifies a novel noncompact Lie symmetry, generated by on-site U(1) fermion number and non-on-site Majorana translation, that enforces the existence of Fermi surfaces with at least two noncontractible components in quantum lattice fermion models, thereby realizing a powerful form of symmetry-enforced gaplessness.
This paper reveals that type-II hyperbolic lattices exhibit higher-order topological phases characterized by a generalized quadrupole moment, featuring zero-energy cornerlike states localized on both inner and outer boundaries that remain robust against weak disorder.
Using a machine learning potential with ab initio accuracy, this study predicts a weakly hydrophilic contact angle for free-standing graphene and reveals that its wettability is highly sensitive to mechanical strain due to the coupling between the contact line and intrinsic thermal ripples, offering a new mechanism for controlling wetting in 2D nanomaterials.
This study reports the electrical characterization of atomically thin -RuCl films in tunnelling transistors, revealing n-type semiconducting behavior at room temperature and providing the first electrical evidence of single antiferromagnetic magnon modes below the Néel temperature, which supports the preservation of bulk magnetic signatures in the two-dimensional limit and paves the way for exploring quantum spin liquid states and Majorana excitations.
This paper employs the Floquet-Magnus expansion to demonstrate that polarization ellipticity and the relative angle between electron momentum and the driving field serve as independent, tunable control parameters for the effective Rabi dynamics and occupation timing of resonantly driven Dirac electrons in graphene.
This study demonstrates that integrating hexagonal boron nitride (hBN) thin flakes as heat spreaders can reduce plasmonic heating in aqueous environments by up to 60% compared to glass, with cooling efficiency governed by flake thickness and interfacial thermal conductance, as validated through finite-element simulations and cross-grating wavefront microscopy experiments.
Using the Keldysh formalism, this study derives particle and entropy current-bias characteristics for a superfluid quantum point contact connecting two Fermi-gas reservoirs, revealing an oscillatory entropy current at low voltages in the ballistic limit and comparing these theoretical findings with experimental data from unitary cold atomic gases.
This study reveals that coupling a non-Hermitian chain exhibiting skin localization with a delocalized chain induces a pseudo mobility edge in the complex energy plane that separates localized and extended states while enabling unidirectional transport, with the system's transition to trivial extended phases characterized by a quantized winding number under specific boundary conditions.
This paper demonstrates that non-local density-density interactions can further amplify the tunneling density of states (TDOS) enhancement near a superconductor-Luttinger liquid junction, while revealing that the spatial dependencies of TDOS and the induced pair potential are distinct, indicating that TDOS enhancement cannot be directly attributed to the proximity-induced pair potential.
This paper demonstrates that in a parafermion Josephson junction formed by proximitized counter-propagating quantum Hall edge modes, an externally controllable difference in edge lengths induces a spontaneous phase bias, enabling electrical control over Majorana or parafermion zero modes depending on the Laughlin filling fraction.
