This paper demonstrates that parallel metal gates placed above a two-dimensional electron system create a plasmonic cavity with unconventional mode quantization, where the lowest resonance occurs at a slot width of one-eighth the plasmon wavelength due to a unique phase shift upon reflection from the gate edge.
This paper demonstrates that spacetime curvature in and black hole backgrounds induces an effective magnetic field and chiral chemical potential for Dirac fermions, driving asymmetric real-time transport and entanglement dynamics confined within inhomogeneous Lieb-Robinson cones that are diagnostic of curvature and horizon effects.
This paper demonstrates that in MoTe/WSe moiré bilayers at two holes per unit cell, long-range Coulomb interactions can induce a robust Quantum Valley Hall insulating phase and, when combined with a small Zeeman field, drive a transition to a Quantum Anomalous Hall state, while also revealing a competition between -wave and -wave topological symmetries arising from band mixing.
This paper develops a symmetry-controlled theory predicting that temperature gradients in insulating altermagnets generate anisotropic thermomagnonic torques, leading to unique phenomena such as reduced domain-wall velocities and anisotropic skyrmion motion with suppressed transverse deflection.
This study demonstrates that K-ion intercalation in electrodeposited Prussian blue analogs drives reversible nanoscale resistive switching, establishing a low-cost, scalable, and ultrafast memristive platform suitable for neuromorphic and memory applications.
This paper proposes a method to detect weak Lorentz-violating backgrounds in noncentrosymmetric crystals by measuring a distinct -periodic angular modulation in the nonlinear shift photocurrent, which arises from momentum-odd corrections to the Bloch Hamiltonian and offers sensitivity to coupling strengths as low as .
This study demonstrates through fully self-consistent nonequilibrium Green's function calculations that weak electron-phonon coupling in helical molecular junctions is insufficient to generate significant chiral-induced spin selectivity (CISS) in two-terminal transport, yielding negligible spin polarization contrary to results from approximate treatments.
This paper establishes a rigorous, model-independent criterion for finite-temperature quantum adiabaticity in driven many-body systems by deriving bounds on mixed-state fidelity that reveal a universal scaling where the threshold driving rate factorizes into zero-temperature system-size contributions and a temperature-dependent factor that transitions from unity at low temperatures to linear behavior at high temperatures.
This paper demonstrates that by optimizing intermediate tunnel couplings and utilizing squeezed input fields, donor-based flip-flop spin qubits can simultaneously achieve strong coupling to superconducting resonators and high-fidelity readout, effectively resolving the inherent trade-off between coupling strength and coherence time.
This study demonstrates that photoelectrical readout of nitrogen-vacancy centers in diamond, when limited by Johnson-Nyquist noise, can achieve magnetic field sensitivity an order of magnitude better than conventional optical readout, paving the way for advanced on-chip magnetometers.
