Dynamical RG on sheared O(n) model identifies new stable Gaussian fixed point with upper critical dimensions d_up=2 (Model A) and d_up=0 (Model B), making mean-field behavior valid in low dimensions and lowering the lower critical dimension below 2.
Sign-free DQMC on three-valley Hubbard models at three electrons per cell maps an extended intermediate-coupling regime with competing local-moment formation and itinerancy, plus U(6) crossovers to ordered states, for near-isotropic interactions relevant to materials like twisted SnSe2.
Exact mapping of Ising-Heisenberg model on extended Lieb lattice to square-lattice Ising model identifies continuous and discontinuous thermal phase transitions confirmed by simulations.
New analytic constructions yield quantum lattice models with continuous symmetry breaking and chiral topological order at arbitrarily high temperatures via entropic stabilization.
DFT and atomistic spin dynamics calculations predict that 1T-CrSI, 1H-CrSeI, and 1H-CrSI Janus monolayers are ferromagnets with perpendicular magnetic anisotropy and Curie temperatures of 210-410 K.
Field theory models with Robin boundary conditions and modular invariance reproduce zero-winding holographic superconductor results in 2D CFTs and interpret fractional vortices via a Little-Parks toy model.
Simulations of the 3D Hubbard-Holstein model at half-filling find antiferromagnetic and charge-ordered insulators separated by a first-order transition with no intervening metal, plus metallic bipolaronic states and pseudogap features at higher temperatures.
A mechanical model of confined active polar disks with dual alignment mechanisms produces robust collective states of high-frequency oscillations and low-frequency milling across varied conditions.
DFT plus Monte Carlo simulations predict itinerant ferromagnetism with Tc exceeding 160 K in p-doped MoS2 monolayers at 9% V concentration.
Padé approximation reduces the polynomial degree and computation time for accurate critical temperature estimates from Fisher zeros in 2D Ising and XY models.
A unified equation describes saturation magnetization loss from finite-size effects in weakly disordered spin-1/2 ferromagnets and yields a unified Bloch equation plus spin transport expression.
