Quantum weight and low-loss EELS signatures of Wannier quantum geometry in black phosphorus

This paper establishes a first-principles framework linking the momentum-resolved quantum metric of black phosphorus to the experimentally accessible direction-resolved quantum weight via low-loss electron energy-loss spectroscopy (EELS), demonstrating that despite strong band-mass anisotropy, the restricted in-plane quantum weight remains nearly isotropic and serves as a practical probe for integrated quantum geometry.

Exciton valley depolarization in monolayer MoS2: non-Markovian quantum dynamics, intervalley scattering, and the breakdown of the Dyakonov-Perel mechanism

Using a first-principles nonequilibrium exciton Green's function approach, this study overturns the conventional Dyakonov-Perel paradigm by demonstrating that large-momentum intervalley scattering, rather than intravalley scattering, dominates exciton valley depolarization in monolayer MoS2, while also revealing the limitations of Markovian Lindblad frameworks in accurately capturing non-Markovian quantum dynamics.

A crystal-field route to THz-driven magnetization

This paper demonstrates that resonant excitation of localized 4 $f$ crystal-field transitions in the paramagnetic insulator CeF $_3$ by circularly-polarized terahertz light provides a novel microscopic pathway for generating and manipulating helicity-dependent magnetization, thereby identifying crystal-field excitations as a dynamic reservoir for optical angular momentum.

An Efficient Method for Gibbs Free Energy Evaluation under Volume Compression

This paper presents an efficient interpolation-based method that significantly reduces the computational cost of calculating Gibbs free energies under volume compression by utilizing a limited number of ab initio phonon calculations and effective Grüneisen parameters, achieving high accuracy comparable to the quasi-harmonic approximation while offering speedups of nearly 6 to 9 times.

Physical aging of glasses of an organic semiconductor

This study reveals that while liquid-cooled TPD organic semiconductor glasses exhibit thickness-independent volume recovery coupled to bulk enthalpy dynamics, those prepared via room-temperature physical vapor deposition demonstrate exceptional resistance to physical aging, offering a pathway to more durable organic electronic devices.

Complex polar superstructure controlled thermal conductivity in ferroelectric PbTiO3/SrTiO3 superlattices

This study demonstrates that the three-dimensional arrangement of polar vortices in ferroelectric PbTiO3/SrTiO3 superlattices significantly suppresses thermal conductivity through a mechanism distinct from standard interfacial scattering, offering a new strategy for actively modulating heat transport via complex polar superstructures.

Nanoscale imaging of reduced forward bias at V-defects in green-emitting nitride LEDs

Using a scanning tunneling luminescence microscope as a local hole injector, researchers confirmed that V-defects in green-emitting III-nitride LEDs enhance electrical efficiency by reducing the forward bias required for charge injection by 1 V due to lowered barrier heights in thinned quantum wells.
