Equivalent Circuit Representation and Thermodynamic Limitations of Non-Adiabatic Spin-Transfer Torque effect

This paper demonstrates that the non-adiabatic spin-transfer torque (β\beta-term) in current-driven domain walls cannot be modeled by passive circuit elements alone without violating thermodynamic principles, implying that experimental interpretations relying solely on this term are incomplete and must account for additional physical effects beyond spin dynamics.

Few-body bound states in the anyon-Hubbard model

This paper theoretically demonstrates that the anyon-Hubbard model hosts exact few-body bound states in the continuum for arbitrary statistical phases, which are stabilized by a unique kinematic mechanism rather than conventional interactions and exhibit fast chiral transport properties that can be experimentally probed via expansion dynamics.

Roto-translational optomechanics

This review provides a comprehensive overview of levitated optomechanics with a specific focus on the classical and quantum aspects of roto-translational motion in optically levitated anisotropic objects, detailing the underlying mechanisms, experimental approaches, and future applications such as quantum-limited torque sensing and the creation of non-classical states.

Orbital magnetization and magnetic susceptibility of interacting electrons

This paper rigorously derives formulas for the orbital magnetization and magnetic susceptibility of interacting electrons within the Hartree-Fock approximation, revealing that while magnetization follows the non-interacting form with Hartree-Fock replacements, susceptibility requires an additional interaction-induced term, a finding validated through tests on an interacting Rashba model.

Fingerprinting superconductors by disentangling Andreev and quasiparticle currents across tunable tunnel junctions

This paper demonstrates that tunneling Andreev reflection (TAR) spectroscopy, by leveraging the additivity of excess decay rates to disentangle Andreev and quasiparticle currents, provides a robust, atomically resolved method for identifying superconducting pairing symmetries that overcomes the limitations of traditional conductance-based techniques.

The influence of quantum geometry on the phase boundary and collective excitations of electron liquids and crystals

This study employs time-dependent Hartree-Fock theory on the λ\lambda-jellium model to demonstrate that quantum geometry promotes electron crystallization at higher densities, suppresses Friedel oscillations and plasmon dispersion in the liquid phase via spectral weight transfer, and gives rise to a breathing mode in the crystal phase corresponding to a real-space pseudospin skyrmion lattice.

Quantum oscillations of helical edge states of periodically deformed 2D topological insulator in magnetic field

This paper investigates how a uniform magnetic field induces elastic backscattering in periodically deformed helical edge states of a 2D topological insulator, leading to magnetic-field-periodic oscillations in the forbidden-band widths and edge conductance that arise from a unique semiclassical scattering mechanism controlled by complex infinity in the weak-field regime.
