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.
The paper introduces DielecMIND, an AI framework that combines large-language-model hypothesis generation with physics-validated first-principles calculations to successfully discover and validate five new extreme-kappa dielectric materials, thereby expanding this rare materials class by 35% and establishing a new paradigm for overcoming data scarcity in functional materials discovery.
This paper proposes double circular dichroism (DCD) high harmonic spectroscopy as a novel all-optical probe that utilizes independently controlled circular pump and probe pulses to disentangle and characterize ultrafast bulk and edge photocurrents in topological materials with broken time-reversal symmetry.
This paper introduces a general and efficient semiclassical framework for computing phase-resolved multidimensional single- and double-quantum spectra of anharmonic molecular polaritons, which successfully explains the polariton bleach effect and enables the direct probing of anharmonicity imprints on double-excitation manifolds.
