Current-induced magnetization control in dipolar-coupled nanomagnet pairs and artificial spin ice

This study demonstrates that current-induced spin-orbit torques can be used to electrically control the magnetization of dipolar-coupled nanomagnets and artificial spin ice systems, where the switching threshold depends non-monotonically on the angle between the current and the nanomagnet axis, enabling programmable manipulation for applications like neuromorphic computing.

Strong Spin-Lattice Interaction in Layered Antiferromagnetic CrCl3_\textrm{3}

This study utilizes polarization-resolved Raman spectroscopy and complementary optical measurements to unambiguously assign all Raman-active modes in CrCl3_3 and demonstrates that strong spin-lattice coupling drives pronounced structural and magnetic transitions across its antiferromagnetic, intermediate, and paramagnetic phases.

Near transform-limited single photons from rapid-thermal annealed quantum dots

This study demonstrates that rapid thermal annealing effectively tunes the emission wavelength of self-assembled InAs/GaAs quantum dots while preserving their near transform-limited single-photon emission properties, making it a viable method for optimizing quantum photonic applications.

Lieb-Schultz-Mattis-Type and Laughlin-Type Argument for the Quantum Hall Effect in Lattice Fermions with Spiral Boundary Conditions

This paper derives the condition for the integer quantum Hall effect in interacting two-dimensional lattice systems by employing spiral boundary conditions to treat the system as an extended one-dimensional chain, thereby obtaining the relationship between magnetic flux, Chern number, and electron density directly through a combined Lieb-Schultz-Mattis and Laughlin-type argument without the redundant system-size dependence found in conventional periodic boundary approaches.
