Effect of electric current on optical response of viscous electron-hole plasma

This study demonstrates that in a laser-generated viscous electron-hole plasma within a GaAs channel, the Hall voltage-induced drift of background electrons creates a Hall current that, via Coulomb drag, accumulates light holes to produce a double photoluminescence line from excitons and trions, whereas the absence of this current results in a photoluminescence energy shift associated with heavy holes.

Dirac-like fermions anomalous magneto-transport in a spin-polarized oxide two-dimensional electron system

By utilizing epitaxial engineering to create a ferromagnetic, spin-orbit-coupled 2DES at LaAlO3_3/EuTiO3_3/SrTiO3_3 (111) interfaces, researchers demonstrated anomalous magneto-transport driven by Dirac-like fermions and a non-trivial Berry phase, offering new avenues for spin-orbitronic and topological electronic applications.

Winding-control mechanism of non-Hermitian systems

This paper introduces a winding-control mechanism using conditional boundary conditions to selectively collapse specific periodic boundary spectra onto their open boundary counterparts based on winding numbers, thereby revealing a composite reconstruction of the Brillouin and generalized Brillouin zones and establishing a link between residual imaginary velocity and non-Hermitian topological transitions.

Far-field radiation of bulk, edge and corner eigenmodes from a finite 2D Su-Schrieffer-Heeger plasmonic lattice

This paper employs a coupled electromagnetic dipole formalism to analyze and isolate the far-field radiation patterns of bulk, edge, and corner eigenmodes in a finite 2D Su-Schrieffer-Heeger plasmonic lattice, demonstrating how symmetry breaking and the out-of-plane nature of dipolar resonances dictate mode darkness, Q-factors, and radiation complexity.

Radio-frequency reflectometry in silicon carbide large-area transistors

This paper demonstrates that while gate-based radio-frequency reflectometry fails in large-area silicon carbide transistors at cryogenic temperatures due to carrier freeze-out-induced impedance changes, a modified circuit configuration can restore sensitivity, offering critical insights for designing scalable cryogenic-CMOS quantum systems.

Interface Piezoelectric Loss in Superconducting Qubits

This paper reports the direct observation of interface piezoelectricity at the aluminum-silicon boundary as a distinct dissipation channel in superconducting qubits, demonstrating that it can significantly reduce qubit lifetimes and potentially dominate over two-level system losses at high frequencies.

Observation of flat-bottom U-shaped energy gap in high-Tc nickelate (La,Pr)3Ni2O7 thin films

Using ultra-low temperature STM/S and transport measurements, this study reports the first observation of an energy-symmetric, flat-bottom U-shaped superconducting gap in high-Tc (La,Pr)3Ni2O7 thin films, providing evidence for a nodeless gap function and suggesting the potential for local superconductivity above the liquid nitrogen boiling temperature at ambient pressure.
