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.

Challenges in orbital current-driven domain wall motion in light metal/ferrimagnet heterostructures

This study demonstrates that while orbital currents from light metals (Mn, Ti) can transfer angular momentum to a ferrimagnetic Gd-Fe-Co alloy, they fail to drive domain wall motion due to weak torque conversion and insufficient interfacial stabilization, a limitation that is overcome only by inserting a thin platinum layer to facilitate orbital-to-spin conversion.

Engineering Giant Thermoelectric Performance through Electrode-Coupling Geometry and Magnetic Flux in Quasiperiodic Su-Schrieffer-Heeger Rings

This paper demonstrates that combining magnetic flux, quasiperiodicity, and engineered asymmetric electrode-coupling geometry in Su-Schrieffer-Heeger rings can dramatically enhance the thermoelectric figure of merit to approximately 90 by optimizing quantum interference and energy filtering while violating the Wiedemann-Franz law.

Transparency-engineered SQUID cells for Kerr-free three-wave-mixing Josephson metamaterials

This paper introduces a transparency-engineered rf-SQUID cell design that utilizes asymmetric series junctions and flux bias to independently control the potential expansion, enabling operating points where the detrimental Kerr nonlinearity is suppressed while preserving the cubic nonlinearity required for three-wave-mixing Josephson metamaterials and traveling-wave parametric amplifiers.

Electrostatic splitting of an Edge Magnetoplasmon Resonator

This paper demonstrates that embedding a quantum point contact within an edge-magnetoplasmon resonator allows for the unambiguous detection of integer and fractional quantum Hall states through radiofrequency transmission, while electrostatic gating enables the precise characterization of edge magnetoplasmon paths and the validation of a geometric model for the system.

Dynamical Reduction of Two Series Josephson Junctions to a Synthetic High-Transparency Josephson Element

This paper establishes the quantitative validity and limitations of modeling two series-connected Josephson junctions as a single synthetic high-transparency element under finite-frequency drive, demonstrating that the reduced single-degree-of-freedom description remains accurate at low frequencies but deviates significantly as the drive frequency approaches the plasma-frequency scale.
