Condensed matter physics and materials science form a dynamic partnership, exploring how the collective behavior of atoms gives rise to the unique properties of solids and liquids. This field bridges the gap between fundamental quantum mechanics and the practical engineering of everything from flexible electronics to superconductors, turning abstract theories into tangible innovations that shape our daily lives.

Below are the latest papers in condensed matter and materials science, organized by their most recent publication dates.
This paper presents a method to identify the single length scale parameter of simplified strain gradient elasticity from standard Mode I fracture tests, deriving explicit formulas for brittle materials and regression relations for quasi-brittle materials to capture non-classical size effects using experimental data.
This study combines Raman scattering experiments and theoretical calculations to confirm that the structural phase transition in K₃NiO₂ near 400 K is driven by a soft phonon at the Z point, which splits into A₁ and B₁ modes in the low-temperature chiral phase, while also revealing that certain phonons with nonzero momentum in this phase exhibit pronounced circular atomic motion and nonzero angular momentum.
This paper predicts and demonstrates through first-principles calculations that ferroelectricity can be engineered in nonpolar silicon dioxide crystals by breaking their symmetry via parallel surfaces or uniaxial strain, enabling robust, low-barrier switching at the nanoscale for direct integration into silicon chips.
This paper extends Enrico Fermi's 1932 procedure to the transverse electromagnetic field by using a quantum canonical transformation to derive a gauge-respecting, matter-only Hamiltonian with incoherent current interactions, thereby circumventing Haag's theorem and providing a quantum origin for the longitudinal-transverse splitting of phonons and other excitations.
First-principles calculations demonstrate that substituting group-III elements (B, Al, Ga, In) in Te-encapsulated silicene monolayers systematically tunes their electronic and topological properties, driving a transition from trivial semiconductors to a quantum spin Hall insulator in the In-based variant.
This paper demonstrates that a mechanical vertex model of cellular structures can generate tunable hyperuniform states independent of rigidity, leading to the creation of the Hyperuniform Poisson Ensemble (HyPE) which establishes a fundamental thermodynamic lower bound for the information content of disordered hyperuniform matter.
This paper presents a graphene-enabled, on-chip integrated detector-interferometer that achieves record-high responsivity and phase-sensitive (sub-)terahertz detection, enabling deep sub-wavelength thickness measurements of thin films for diverse industrial applications.
This paper establishes a unified symmetry classification framework based on spin space groups that predicts novel magnetic phases, most notably the coplanar even-wave magnet, and identifies CoCrO4 as a promising candidate for its experimental realization.
Using scanning tunneling microscopy, researchers discovered localized "vortex liquid droplets" in the iron pnictide superconductor CaKAsFe at temperatures as low as 0.5, demonstrating that local dissipation due to thermal fluctuations begins considerably below the critical temperature where macroscopic melting transitions are typically observed.
This study demonstrates that charge-current-driven orbital angular momentum can modulate temperature via the spin Peltier effect in YIG/Pt/CuOx heterostructures, establishing interfacial orbital processes as a distinct channel for heat transport and providing a pathway toward spin-orbit caloritronics.
