This study utilizes advanced spectroscopy to demonstrate that long 48-carbon polyynes exhibit highly delocalized ground states with weakened Peierls distortions and rapid excited-state self-localization, revealing that their electronic properties have plateaued near the carbyne limit and are significantly influenced by chain topology.
This study combines high-velocity impact experiments with a novel micromechanical network model to demonstrate that the dynamic fragmentation of residually stressed glass follows a universal exponential scaling law governed by stress gradients, while revealing that microscopic non-sequential bond breaking drives super-Rayleigh crack instabilities responsible for observed fractographic features.
This paper utilizes a non-perturbative Unitary Renormalization Group approach to demonstrate that a local magnetic field induces a Kondo breakdown entanglement transition, separating a low-energy screened phase from a polarized local-moment phase and revealing a novel non-Fermi liquid critical regime.
This paper theoretically demonstrates that Rashba spin-orbit coupling in altermagnet/triplet superconductor/altermagnet junctions enables a robust, electrically tunable spin valve effect and distinct transport signatures that distinguish between nodal and chiral triplet pairing symmetries, all without requiring ferromagnetic electrodes.
This paper introduces Zandpack, an open-source tool that implements a refined auxiliary mode approach for efficient time-dependent transport simulations of large nanoelectronic systems far from equilibrium, demonstrating its capabilities through applications to spin currents in hydrogenated graphene, electron excitation in graphene nanoribbons, and non-adiabatic behavior in gold break-junctions.
This paper investigates topological Green's function zeros in interacting Floquet systems, specifically Kitaev-like chains in symmetry class BDI, by deriving new topological invariants that account for both bulk and edge zeros (which can exist even without interactions) and proposing a digital quantum emulator circuit to detect these boundary features.
This paper demonstrates that a machine-learning algorithm using tunneling spectroscopy features from sensor dots can reliably tune artificial Kitaev chains to high-quality Majorana sweet spots by balancing crossed Andreev reflection and elastic cotunneling, offering a scalable approach for achieving topological protection in longer chains.
This paper investigates non-Abelian fractional quantum Hall states at filling factor in GaAs hole systems and bilayer graphene, demonstrating through theoretical bootstrap analysis and numerical calculations that these states exhibit Ising anyon topological order with 12-fold ground state degeneracy and specific chiral graviton spectral features consistent with particle-hole conjugate or composite fermion descriptions of Moore-Read type states.
This paper demonstrates an ultrafast, room-temperature method for generating and reading valley-polarized electron populations in bulk silicon and diamond using unidirectional intervalley scattering induced by linearly polarized infrared femtosecond pulses, paving the way for terahertz-frequency valleytronic devices compatible with existing silicon technology.
This paper proposes and theoretically validates a modular qubit architecture utilizing a two-dimensional omnidirectional shuttler to bypass valley-splitting minima in Si/SiGe quantum wells, thereby enabling high-fidelity all-to-all connectivity while avoiding detrimental valley-state excitations.
