The Two Orbital, Interacting Hatano-Nelson Model

This paper investigates the interacting, spinful two-chain Hatano-Nelson model to map out the conditions for a purely real spectrum, analyze the relationship between periodic and open boundary condition modes via winding numbers, and validate the non-Hermitian description's ability to qualitatively capture the low-filling dynamics of such non-equilibrium systems.

Discovery of an odd-parity f-wave charge order in a kagome metal

Using scanning tunneling microscopy and angle-resolved photoemission spectroscopy, researchers discovered an inversion symmetry-breaking odd-parity f-wave charge bond order in the kagome metal CsV3_3Sb5_5, which emerges as an intermediate phase between conventional orders and a subsequent hidden electronic state.

Orbitals of Artificial Atoms in a Gapped Two-Dimensional Vacuum

Using scanning tunnelling microscopy, researchers demonstrated that artificial atoms engineered in a gapped two-dimensional molecular film exhibit familiar ss and pp orbital bonding while also generating entirely new quasi-one-dimensional localized states shaped by the unique electronic vacuum, thereby expanding the fundamental vocabulary of chemical orbitals.

Thermal conductivity tuning of scalable nanopatterned silicon membranes measured with a three-probe method

This paper demonstrates a scalable method for significantly reducing the thermal conductivity of silicon membranes through block copolymer self-assembly and controlled nanohole etching, validated by a novel three-probe technique that overcomes thermal contact resistance challenges to achieve a fivefold reduction in thermal conductivity at room temperature.

Formalizing Poisson-Boltzmann Theory for Field-Tunable Nanofluidic Devices

This paper presents a formally reformulated Poisson-Boltzmann theory that establishes a unified framework for field-tunable nanofluidic transport by classifying electric double layer regimes, thereby explaining experimental scaling behaviors, rationalizing reconfigurable ionic transistors, and predicting fundamental thermodynamic limits for electrostatic modulation.

Poor man's Majorana bound states in quantum dot based Kitaev chain coupled to a photonic cavity

This paper demonstrates that embedding a quantum dot-based Kitaev chain in a photonic cavity allows for the engineering of "poor man's" Majorana bound states by using the cavity's photon state to screen particle interactions and reach the necessary sweet spot conditions, while also revealing that a large photon population suppresses hopping and creates a degenerate spectrum.

Strain Induced Modulation of Local Transport of 2D Materials at the Nanoscale

This paper utilizes conductive atomic force microscopy and molecular dynamics simulations to demonstrate how nanoscale surface topography-induced strain in few-layer transition-metal-dichalcogenides modulates local conductivity by altering effective mass and surface charge density, thereby reducing the Schottky barrier height and enabling new opportunities for strain-based electronic and photonic devices.
