Below are the latest papers in condensed matter and materials science, organized by their most recent publication dates.
Through thermodynamic, muon-spin relaxation, and neutron scattering measurements down to 16 mK, this study reveals that the distorted triangular lattice antiferromagnet TbBO3 exhibits persistent spin-liquid-like dynamics driven by dominant 2D short-range correlations and the interplay of frustration and spin-orbit coupling, despite the absence of long-range magnetic order.
This study employs DFT+U calculations to investigate the low-temperature phase of magnetite, analyzing the relationship between trimeron ordering, bandgap properties, site-selective doping, and polaron hopping energy to elucidate the material's complex electronic behavior.
By combining ARPES and XAS, this study reveals that the oxygen-tuned superconductor-insulator transition in Ruddlesden-Popper bilayer nickelate films is driven by the suppression of coherent quasiparticle spectral weight and significant orbital reconfiguration, establishing a mechanism distinct from carrier doping effects.
This paper theoretically demonstrates and classifies the generation of Néel-order-locked electric polarization in two-dimensional altermagnets, identifying monolayer MgFeN as a prototypical type-II multiferroic and proposing magneto-optical microscopy as a detection method to bridge altermagnetism with multifunctional spintronics.
This paper demonstrates that symmetric crystals can exhibit finite, temperature-persistent angular momentum fluctuations in their phonon vacuum due to quantum coherence between nondegenerate modes, a phenomenon driven by the noncommutativity of the phonon Hamiltonian and angular momentum that generates distinct finite-frequency spectral signatures detectable via time-resolved spectroscopy.
Using low-temperature scanning tunneling microscopy, researchers discovered that the van der Waals metal CeTe3 hosts versatile, competing antiferromagnetic charge-ordered states (stripe and checkerboard) tunable by modest magnetic fields, revealing a rich, strongly correlated electronic landscape that extends beyond weak-coupling descriptions and offers a new platform for engineering tunable nanoscale quantum states.
This study demonstrates that the choice of electron-positron correlation functional, particularly the use of the non-local weighted density approximation (WDA), is critical for accurately predicting positron annihilation lifetimes in lead halide perovskites, revealing that previous discrepancies in theoretical predictions and experimental interpretations of cation vacancies stem from the sensitivity of these materials to the specific approximation used.
This paper demonstrates that unconventional ferroelectricity in graphene-heterostructure systems can be engineered through specific hexagonal boron nitride (hBN) boundaries and line defects, revealing that such behavior arises from localized charge states even without the precise lattice alignments previously thought necessary.
By restoring the exact algebra of the screw dislocation group to establish rigorous symmetry constraints, this study reveals that a piezoelectric effect at the core of screw dislocations in GaN strongly suppresses radiative recombination in favor of non-radiative capture, thereby explaining their detrimental impact on the material's luminous efficiency.
This paper introduces the thermally-averaged Hindley-Mott (TAHM) method, a computationally efficient approach that leverages ab initio molecular dynamics to predict temperature-dependent electronic conductivity in both ordered and disordered materials by thermally averaging fluctuations in the electronic density of states near the Fermi level.
