Gate-modulated reflectance spectroscopy for detecting excitonic species in two-dimensional semiconductors

The authors developed a highly sensitive, gate-modulated reflection spectroscopy technique that successfully enables the detection of excitonic states in two-dimensional transition metal dichalcogenides from cryogenic to room temperatures, thereby offering a superior alternative to conventional reflection methods for investigating exciton physics in these materials and their heterostructures.

Melting of Charge Density Waves in Low Dimensions

This article experimentally demonstrates and elucidates the continuous hexatic melting mechanism of incommensurate charge density waves in low-dimensional materials and reveals a progression from elastic deformations to the nucleation of topological defects through the observation of azimuthal peak broadening, wave vector contraction, and intensity reduction.

Tuning charge-transport properties and magnetic order in metallic EuTiO3−δ_{3-\delta}

This study demonstrates that oxygen-vacancy doping in metallic EuTiO3−δ_{3-\delta} induces a distinct phase diagram compared to cation substitution, driving a transition from antiferromagnetic to ferromagnetic order with a Curie temperature of approximately 11 K, a finding supported by transport measurements, density functional theory, and diffuse scattering data.

A Scalable Translationally Invariant Variational Theory of Ab Initio Polarons

This paper introduces a scalable, translationally invariant variational theory for ab initio polarons that combines momentum-projected wavefunctions with low-rank kernel factorization to accurately model carrier behavior across coupling regimes in the thermodynamic limit, revealing significant biases in existing diagrammatic Monte Carlo results for strong-coupling hole polarons in LiF.

Polarizable atomic multipoles for learning long-range electrostatics

This paper introduces a semi-local framework that integrates polarizable atomic multipoles with non-self-consistent linear response to enable machine learning interatomic potentials to accurately model long-range electrostatics and predict polarization-sensitive observables like Born effective charges and infrared spectra across diverse ionic and polar systems.

Unraveling the Origin of Ferrimagnetic Signatures in (Fe,Mn,Ga)2O3 Bixbyites: The Role of Structurally-Undetectable Spinel Impurities

This study resolves conflicting reports on the magnetic properties of (Fe,Mn,Ga)2O3 bixbyites by demonstrating that observed room-temperature ferrimagnetism is an extrinsic artifact caused by trace, structurally undetectable spinel impurities rather than an intrinsic property of the bixbyite phase.
