Below are the latest papers in condensed matter and materials science, organized by their most recent publication dates.
This paper utilizes first-principles calculations to demonstrate that the sliding barrier of small islands on a graphene-covered substrate, rather than electrostatic potential, serves as the most rigorous metric for predicting the viability of remote epitaxy, suggesting the phenomenon is governed by island migration kinetics.
High-precision heat-capacity measurements of submonolayer He on graphite reveal a second-order transition between two striped domain-wall phases below 1 K, where the melting of the fixed-spacing phase into the variable-spacing phase supports the existence of a quantum nematic state characterized by one-dimensional phonons.
By combining THz-range Raman scattering, single-crystal X-ray diffraction, and first-principles calculations, this study reveals that formamidinium lead bromide possesses a unique coexistence of intrinsic local static disorder and a well-defined average crystal structure, where the former significantly influences the material's structural dynamics and phase transitions across the 10–300 K temperature range.
This study experimentally identifies the 3R polytypes of TaS and NbS as Kramers nodal line metals featuring tunable Octdong and Spindle-torus Fermi surfaces, respectively, and proposes a strain-induced phase transition to conventional metals alongside potential size quantization effects in natural inclusions.
Using angle-resolved photoemission spectroscopy, researchers successfully created, detected, and controlled quasi-steady dark excitons in doped SnSe2, revealing a novel anisotropic excitonic gap phase that extends the study of dark excitons from ultrafast timescales to quasi-equilibrium conditions.
This study reports the observation of electrostatic gate-controlled Altshuler-Aronov-Spivak quantum interference oscillations in a high-mobility two-dimensional electron gas at the (LaSr)(AlTa)O/SrTiO interface, attributed to closed-loop paths along SrTiO domain walls and demonstrating a long phase coherence length that highlights the potential of complex oxide interfaces for quantum technologies.
This paper presents a novel methodology using -learning with a dispersion-corrected tight-binding baseline to train machine-learning interatomic potentials that achieve CCSD(T) accuracy for systems with extended covalent networks and van der Waals interactions, enabling large-scale, chemically accurate simulations of materials like covalent organic frameworks.
This study demonstrates that van der Waals stacking of WS and ReSe with distinctive crystal phases enables highly anisotropic enhancement and suppression of second-harmonic generation through interlayer hybridization and band renormalization, rather than simple band alignment.
This paper introduces the concept of "orbital altermagnetism," a symmetry-protected magnetic order characterized by staggered orbital moments and momentum-dependent band splittings that arises from loop currents in specific lattice structures and is predicted to exist in materials like CuBr and VS, offering new opportunities for orbital-based spintronics.
This paper presents a computational framework that combines database analysis with microscopic modeling to predict and identify promising new molecular single-photon emitters, successfully benchmarking the approach on dibenzoterrylene and discovering novel candidates like a chiral emitter.
