This paper identifies the topological phase diagrams of coupled Su-Schrieffer-Heeger wires, revealing that diagonally coupled systems support rich insulating phases with winding numbers up to the number of wires and flat bands, while perpendicularly coupled systems exhibit nontrivial topological phases only when an odd number of wires are involved, characterized by specific symmetry constraints and confined correlations.
This study experimentally demonstrates that silicon DRAM cells cannot achieve the Landauer limit for information erasure due to the thermodynamic constraint of being unable to prepare the initial state in thermal equilibrium, a finding that establishes tighter, practically relevant energy efficiency limits for electronic circuits.
This paper proposes a non-Hermitian tight-binding model with gain/loss and non-reciprocal hopping that emulates black-hole physics by mapping a 1D lattice interface to a Schwarzschild metric, enabling the theoretical calculation of Hawking radiation, temperature, entropy, and mass, along with a proposed experimental realization for detecting these elusive features.
This paper establishes a non-perturbative topological constraint on the current of sliding electron crystals in magnetic fields, showing that the current depends on the many-body Chern number and determining a counting rule for gapless phonon modes based on whether the net current vanishes.
This review systematically explores the multifaceted nature of altermagnetism in by analyzing its crystal and magnetic structures, electronic properties, and transport phenomena, while critically assessing the ongoing debate regarding its intrinsic magnetism and outlining future research directions.
This paper illustrates the spectrum tomography of a ring-shaped Bose-Hubbard circuit coupled to an electromagnetic cavity, revealing a phase diagram where inter-particle interaction and cavity coupling govern the transitions between superfluid, superconducting, and Mott insulator regimes, alongside a vast region of fragmented chaotic states.
This paper presents a robust convolutional neural network trained on realistic micromagnetic simulations that accurately and reliably estimates interfacial Dzyaloshinskii-Moriya interaction strength from magnetic bubble domain textures, offering a fast and quantitative alternative to inconsistent experimental methods.
This paper demonstrates that quantum coherence and multipartite entanglement, rather than classical thermodynamics, govern the macroscopic polymorphism of copper phthalocyanine during organic vapor phase deposition, enabling the rational design of a new crystal polymorph through the proposed DIME framework.
This paper identifies a distinct mechanism for fractionalization in doped two-dimensional SU(4) quantum magnets on frustrated triangular lattices, where hole doping relieves kinetic frustration by splitting holes into fermionic spinons and bosonic holons, while electron doping drives the system into a ferromagnetic phase.
This paper introduces MTNet, a unified multiscale auxiliary physics-informed neural network framework that overcomes the computational and numerical limitations of traditional solvers by recasting the generalized phonon radiative transfer equation into a fully differential system, thereby enabling high-fidelity simulation of ballistic-diffusive transport and the solution of geometric inverse problems in nanoscale thermal systems.
