The "Cond-Mat — Other" category captures the diverse and often unexpected corners of condensed matter physics, a field that studies how matter behaves in its solid and liquid states. While the main subfields focus on specific materials or phenomena, this section gathers the eclectic mix of research that doesn't fit neatly elsewhere, ranging from novel theoretical models to experimental studies of unusual quantum systems. It is a space where curiosity drives discovery, often bridging gaps between established theories and the next big breakthrough.
Gist.Science monitors every new preprint in this category as it appears on arXiv, ensuring you never miss these emerging insights.

Below are the latest papers in this dynamic collection, ready for you to explore.
This paper demonstrates the feasibility of running a modern multimodal assistant entirely on a 2011 6GB Fermi GPU by engineering an all-GPU inference engine that overcomes hardware limitations through optimized dequantized GEMMs, chunked recurrent layers, and memory-efficient attention kernels, achieving end-to-end image-question answering in 1.7 seconds.
This paper establishes a scaling law that expresses the second-order nonlinear Hall conductivity as a polynomial of the linear longitudinal conductivity, where distinct "weight fingerprints" for each mechanism allow for the quantitative disentanglement of quantum-geometric contributions from disorder-induced backgrounds in experimental data.
This study employs first-principles calculations to reveal that electric-field-driven magnetization switching in FePt/BaTiO heterostructures arises from strain-controlled orbital reconstruction at the interface, which modulates spin-orbit coupling to reverse the magnetic easy axis and offers a pathway for ultra-low-power magnetic memory.
This paper introduces a novel framework that unifies finite-element methods with tensor networks to transform complex, non-linear operator equations into linear matrix equations, enabling efficient variational solutions through a common algebraic structure.
This study demonstrates that the anomalous gating effects in bilayer graphene/BN heterostructures are governed by the relative angular alignment between the two encapsulating BN layers rather than graphene moiré superlattices, with a specific 15°–45° misalignment range acting as an ON/OFF switch for these phenomena at room temperature.
This study utilizes ultrafast pump-probe spectroscopy to reveal the direct interplay between spin-orbit entangled excitons and magnetic ordering in the van der Waals antiferromagnet NiPS3, demonstrating distinct relaxation timescales for excitonic coherence and spin reordering that exhibit critical behavior near the exciton dissociation and Néel temperatures.
This paper investigates electro-acoustic perturbative modes in expanding FLRW Jellium models by providing novel analytic solutions and numerical evaluations of their linear and nonlinear evolution, while introducing a scale-dependent power spectrum to bridge theoretical predictions with experimental observations.
This paper develops a microscopic quantum membrane paradigm for black holes by modeling the horizon as a fuzzy sphere populated by half-filled Fermi sea partons, demonstrating how their coupling to a Berry monopole generates Lowest-Landau-Level currents that dynamically lock to external fields, thereby replacing the classical fictitious membrane with a dynamical quantum structure that yields frequency- and helicity-dependent corrections to horizon boundary conditions.
This paper identifies a novel time-reversal-invariant topological metallic phase in a bilayer Lieb lattice characterized by a quantized layer-resolved pseudo-spin Chern number, where specific orbital-angular-momentum-dependent couplings tune the system between semimetallic and metallic regimes while preserving distinct, asymmetric edge states that can be selectively manipulated via interlayer and intralayer interactions.
This paper demonstrates that resonant excitation of localized 4 crystal-field transitions in the paramagnetic insulator CeF by circularly-polarized terahertz light provides a novel microscopic pathway for generating and manipulating helicity-dependent magnetization, thereby identifying crystal-field excitations as a dynamic reservoir for optical angular momentum.
