Emergent Quantum-Geometric Equivalence of Injection and Shift Currents

This paper reveals that injection and shift currents, traditionally viewed as distinct nonlinear optical responses, become equivalent in systems with linear electronic dispersion (such as Dirac and Weyl semimetals) because both are governed by the same interband quantum-geometric dipole, establishing a unified framework for interpreting these phenomena.

An ab initio approach to energy alignment and charge-state prediction of adsorbates on ultrathin insulators

This paper presents a computationally efficient, first-principles framework that combines GW calculations, quasiparticle renormalization, and integer charge transfer models to accurately predict energy-level alignment and charge states of adsorbates on ultrathin insulators, thereby enabling the high-throughput screening of molecular qubits and organic electronic interfaces.

Effect of spin-dependent tunneling and intervalley scattering in magnetic-semiconductor van der Waals heterostructures on exciton and trion polarization

This paper presents a theoretical analysis demonstrating how spin-dependent interlayer charge transfer and intervalley scattering in magnetic-semiconductor van der Waals heterostructures govern the photoluminescence polarization dynamics of excitons and trions, enabling long-distance manipulation and sign switching of valley pseudospin.

Magnetization alignment in spin-transfer-torque magnetic random-access memory

This paper presents a systematic micromagnetic study of 30 nm p-STT-MRAM nanopillars, demonstrating that introducing asymmetry in synthetic antiferromagnet reference layers reduces the coupling strength needed to stabilize antiparallel states and optimizes energy barriers for reliable device operation, supported by a publicly released dataset of 4,374 configurations.

Coherence, long-range transport and nuclear polarization in a driven-dissipative dark exciton condensate

This paper reports direct evidence of macroscopic coherence and millimeter-scale long-range transport in a driven-dissipative dark exciton condensate within coupled quantum wells, where gain-loss competition and dynamic nuclear polarization enable a stable, electrically tunable quantum fluid exhibiting unique hysteresis and interference phenomena.

Diamond membranes: platform for photonic and opto-mechanical applications

This paper presents diamond membranes as a versatile platform for photonic and opto-mechanical applications by characterizing their IR dichroism in gratings, demonstrating femtosecond laser cutting via carbonization and oxidation, and modeling light intensity distributions in form-birefringent structures.

Families of planar lattices with arbitrarily high TcT_{\rm c} for the ferromagnetic Ising model

This paper constructs families of periodic planar lattices, specifically Apollonian lattices, that achieve arbitrarily high critical temperatures for the ferromagnetic Ising model by demonstrating that TcT_{\rm c} scales logarithmically with the maximal coordination number and conjecturing this family to be optimal for such systems.

Orbital and Spin Nernst Effects in Monolayers of Transition Metal Dichalcogenides

This paper demonstrates that monolayer transition metal dichalcogenides serve as an ideal platform for observing both orbital and spin Nernst effects, revealing that the orbital Nernst effect arises intrinsically without spin-orbit coupling while the spin Nernst effect scales with it, with both phenomena being tunable via doping in semiconducting MoS2_2 and intrinsically present in metallic NbS2_2.
