This study utilizes finite element modeling to demonstrate that optimizing material properties and geometric parameters in nanoscale magnetoelectric composite pillars can overcome scaling limitations to generate output voltages exceeding 200 mV, thereby highlighting their potential for microelectronic integration.
This paper presents a parameter-free microscopic approach that successfully reproduces experimental photoluminescence spectra of CdSe/CdS nanocrystals by demonstrating that second-order diagonal vibronic couplings are the dominant source of homogeneous linewidth broadening at temperatures above 100–150 K, while off-diagonal couplings play a negligible role until near room temperature.
This paper demonstrates a real-time protocol for retrieving the amplitude and phase of AC magnetic fields using nitrogen-vacancy centers in diamond from single-shot measurements, achieving high sensitivity and temporal resolution while addressing challenges like frequency detuning and strong field regimes.
Using the numerically exact hierarchical equations of motion method, this study reveals that strong light-matter coupling in optical cavities fundamentally alters electron transfer dynamics by inducing saturation in the strong-coupling regime and generating non-monotonic, oscillatory rate behaviors through vibronic polariton formation and quantum interference among electronic, vibrational, and photonic degrees of freedom.
This paper demonstrates that in an interacting Su-Schrieffer-Heeger chain coupled to a metallic substrate, the emergent Kondo temperature is directly controlled by the topological mass parameter, collapsing linearly near the topological transition and providing a mechanism to explain soliton-induced Kondo signatures in graphene nanoribbons.
This paper demonstrates through time-resolved simulations that while electron-electron interactions renormalize the velocity of ultrashort voltage pulses in a Mach-Zehnder interferometer, the resulting interference effects remain robust.
This paper reviews recent advances in two-dimensional magnets and their heterostructures, highlighting how their unique magnetic properties and atomically sharp interfaces enable tunable, energy-efficient spintronic devices for applications ranging from neuromorphic computing to hybrid quantum systems.
This study demonstrates that embedding silver nanoparticles in the top electrode of TaO-based memristors effectively suppresses one of two competing resistive switching loops and reduces cycle-to-cycle variability by locally metallizing the interface to confine filament dynamics, thereby enhancing switching stability without altering the oxide architecture.
This paper proposes and theoretically demonstrates a "Kapitza supercurrent diode" that achieves nonreciprocal supercurrent transport in conventional Josephson junctions by using frequency-modulated parametric driving to dynamically break reciprocity, offering a magnet-free alternative to existing superconducting diode designs.
This paper proposes a symplectic quantum geometric tensor (SQGT) to provide a complete geometric characterization of bosonic Bogoliubov quasiparticles, linking its real and imaginary parts to a quantum metric and Berry curvature, respectively, and demonstrating how to measure these components via excitation rates and their connection to anomalous velocities.
