This paper analyzes electron-vibrational coupling and optical phonon relaxation in highly oblate InAs/GaAs nanoclusters, revealing how their specific ellipsoidal geometry and angular momentum conservation lead to the emission of chiral optical phonons and nonmonotonic size dependences in the electron-phonon coupling coefficient.
Using quantum field theory of linearized gravity, the paper demonstrates that the Berry curvature of right- and left-handed gravitons induces a spin Hall effect in curved spacetime, resulting in a helicity-dependent energy current splitting that is exactly twice the magnitude of the corresponding effect for photons.
This paper investigates thermoelectric transport in monolayer graphene across complex barriers, demonstrating that the imaginary potential induces non-unitary scattering and tunable anomalous transmission, where gain and loss mechanisms selectively modify conductance profiles and optimize the thermoelectric figure of merit.
This paper investigates how magnon ellipticity, arising from transverse magnetic anisotropy in easy-plane ferromagnets, influences diffusive spin and heat transport, revealing that while spin conductivity is enhanced or suppressed depending on the anisotropy axis, thermal conductivity is consistently enhanced in both easy- and hard-axis systems.
This paper demonstrates that steady-state density functional theory (i-DFT), equipped with newly constructed exchange-correlation functionals, accurately and efficiently computes the spectral and transmission properties of multiple correlated quantum dots across various interaction regimes, achieving results comparable to many-body approaches at a significantly lower computational cost.
This paper demonstrates a highly tunable artificial electrostatic crystal platform in a GaAs quantum well that enables the continuous electrical manipulation of bandstructures into graphene-like and kagome-like geometries, revealing a unique loop-current Wigner insulator state at half-filling of the kagome flat band.
This study demonstrates that vacuum field fluctuations in engineered cavities can control correlated electronic phases by stabilizing thermally disordered quantum Hall stripes, resulting in striking anisotropies and suppressed longitudinal resistance in a two-dimensional electron gas at ultra-low temperatures.
This study predicts the zero-field coexistence of degenerate bimerons and antibimerons in a FeGeTe/CrGeTe van der Waals heterostructure and demonstrates that their unique structural symmetry and unbroken rotational invariance lead to distinct anisotropic interactions and entropic lifetime effects, establishing them as superior candidates for non-linear soliton-based computing compared to skyrmions.
This paper introduces a universal variational framework for mapping Bloch bands to generalized Landau levels and applies it to twisted MoTe to predict the formation of Abelian fractional Chern insulators and, under specific conditions, a non-Abelian Moore-Read state at filling .
This paper proposes a response-based diagnostic using minimal pseudo-Lorentz-symmetry-breaking deformations to distinguish irreducible non-Hermitian effects from mere parameter renormalizations in Dirac materials with real spectra, identifying specific bulk observables like density of states slope and shear viscosity that serve as effective probes of non-Hermiticity.
