This paper theoretically investigates a triangular spin-1/2 cluster with Dzyaloshinskii-Moriya interaction, revealing distinct magnetic phases, a characteristic 1/3 magnetization plateau, and complex magnetocaloric effects that are significantly enhanced by the interplay of frustration and anisotropy.
This paper demonstrates that shape-memory alloy-polymer composite rods exhibit hysteretic acoustic band structures, where the stop-band edges and transmission spectra form closed loops in the temperature-frequency plane due to the material's thermal hysteresis, while the spectral hysteresis width can be further tuned by adjusting the geometric filling fraction.
This paper presents a unified theoretical framework based on a Lindblad master equation to describe both coherent exchange interactions and dissipative spin torques in molecular quantum dots, demonstrating how time-modulated tunneling can induce electron spin resonance and explaining transport-driven decoherence in coupled spin systems.
This study demonstrates that a high-power pumping wave can induce a significant nonlinear phase shift of up to 180° in low-power forward volume spin waves within perpendicularly magnetized yttrium iron garnet films, offering a pathway for fast and energy-efficient control of one-dimensional magnon transport.
Using a Keldysh path integral formulation, this paper demonstrates that while weakly coupled continuous variable quantum systems exhibit strong phase correlations, their synchronization ultimately breaks down due to the proliferation of quantum phase slips, a mechanism that also elucidates non-Markovian effects in systems like superconducting resonators coupled via a voltage-biased double quantum dot.
Using nanoSQUID-on-tip magnetometry, this study provides direct evidence for the chiral nature of a zero-resistance state in electron-doped rhombohedral multilayer graphene by mapping its finite orbital magnetic moment, while also revealing how valley-resolved magnetic moment sign changes drive stochastic resistivity switching and magnetic inhomogeneity near the superconducting phase.
This paper theoretically demonstrates that the coupling of free electrons to radiative modes near distant extended objects causes a macroscopic, long-range depletion of quantum coherence in electron interference, an effect that vanishes with path separation and offers a potential method for nondestructively sensing distant objects and measuring vacuum temperature.
This paper investigates a multi-terminal triple-dot quantum refrigerator that utilizes nonthermal resources to achieve cooling without average energy extraction, demonstrating that exploiting the resource's nonthermal properties yields significantly higher cooling-power precision and suppressed fluctuations compared to regimes relying on information.
This paper employs the Painlevé-Gullstrand metric to demonstrate that the surface of a Lifshitz transition separating type-I and type-II Weyl fermions acts as an emergent black hole horizon, exhibiting unique features such as a Dirac-line Fermi surface, nontrivial topological order, and Hawking radiation.
Using finite-size exact diagonalization and neural network analysis, this study demonstrates that the interplay of interactions and Anderson disorder in the spinful Haldane model induces an antiferromagnetic topological Anderson insulator with Chern number , a phase driven by disorder-generated charge imbalance rather than staggered mass.
