Contributions to Plasma Physics, EarlyView.ABSTRACT The properties of plasmas in the low‐density limit are described by virial expansions. Analytical expressions are known for the lowest virial coefficients from Green's function approaches. Recently, accurate path‐integral Monte Carlo (PIMC) simulations were performed for the hydrogen plasma at low densities by Filinov and Bonitz (Phys. Rev.

Decomposition of Regular Bipartite Graphs Into Hamiltonian Cycles (Paths) and S3
Journal of MathematicsLet G be either a complete bipartite graph with n (even) vertices in each partite or a complete bipartite graph with n (odd) vertices in each partite plus a 1‐factor.

Contributions to Plasma Physics, EarlyView.ABSTRACT Ab initio path integral Monte Carlo (PIMC) simulations constitute the gold standard for the estimation of a broad range of equilibrium properties of a host of interacting quantum many‐body systems spanning a broad range of conditions from ultracold atoms to warm dense quantum plasmas.

Ultrafast Transitions in X‐Ray Irradiated Solids
Contributions to Plasma Physics, EarlyView.ABSTRACT In this review, we present current developments on modeling ultrafast transitions in solids triggered by intense, atto‐ to femtosecond pulses from X‐ray free electron lasers. This specific irradiation regime requires dedicated simulation tools based on theoretical and computational methods, involving the elements of classical and quantum ...

Matching Lagrangian and Hamiltonian simulations in (2+1)-dimensional U(1) gauge theory
European Physical Journal C: Particles and FieldsAt finite lattice spacing, Lagrangian and Hamiltonian predictions differ due to discretization effects. In the Hamiltonian limit, i.e. at vanishing temporal lattice spacing $$a_t$$ a t , the path integral approach in the Lagrangian formalism reproduces ...

Stopping Power of Electron Liquid for Slow Quantum Projectiles
Contributions to Plasma Physics, EarlyView.ABSTRACT We revisit the problem of the deceleration of a charge moving in a medium. In the low‐velocity limit of the projectile, we construct the fully nonlinear (in the charge–target interaction) theory of the stopping power (SP), which goes beyond the classical Ehrenfest dynamics.

European Journal of Inorganic Chemistry, EarlyView.Magneto‐structural correlation in bis‐μ‐hydroxido Cu(II) dimers: The out‐of‐plane angle (α) of bridging hydroxido groups critically influences the exchange coupling constant (J). A three‐dimensional correlation combining α and the Cu‐OH‐Cu angle (θ) enables computationally accurate J prediction.

Hamiltonian paths on 3-polytopes
Journal of Combinatorial Theory, Series B, 1972 AbstractThe smallest number of vertices, edges, or faces of any 3-polytope with no Hamiltonian path is determined. Similar results are found for simplicial polytopes with no Hamiltonian path.

Tight Bounds for Hypercube Minor‐Universality
Journal of Graph Theory, EarlyView.ABSTRACT A graph G $G$ is m $m$‐minor‐universal if every graph H $H$ with at most m $m$ edges and no isolated vertices is contained as a minor in G $G$. Recently, Benjamini, Kalifa and Tzalik proved that there is an absolute constant c>0 $c\gt 0$ such that the d $d$‐dimensional hypercube Qd ${Q}_{d}$ is (c⋅2d/d $c\cdot {2}^{d}/d$)‐minor‐universal ...
