An Energy Consistent Discretization of the Nonhydrostatic Equations in Primitive Variables
Journal of Advances in Modeling Earth Systems, 2020 We derive a formulation of the nonhydrostatic equations in spherical geometry with a Lorenz staggered vertical discretization. The combination conserves a discrete energy in exact time integration when coupled with a mimetic horizontal discretization ...

Structure-preserving discretization for port-Hamiltonian descriptor systems [PDF]
IEEE Conference on Decision and Control, 2019 We extend the modeling framework of port-Hamiltonian descriptor systems to include under- and overdetermined systems and arbitrary differentiable Hamiltonian functions.

Torus–Connected Cycles: A Simple and Scalable Topology for Interconnection Networks
International Journal of Applied Mathematics and Computer Science, 2015 Supercomputers are today made up of hundreds of thousands of nodes. The interconnection network is responsible for connecting all these nodes to each other.

Variational quantum algorithms for discovering Hamiltonian spectra [PDF]
Physical Review A, 2018 Calculating the energy spectrum of a quantum system is an important task, for example to analyse reaction rates in drug discovery and catalysis. There has been significant progress in developing algorithms to calculate the ground state energy of ...

Coupling and convergence for Hamiltonian Monte Carlo [PDF]
The Annals of Applied Probability, 2018 Based on a new coupling approach, we prove that the transition step of the Hamiltonian Monte Carlo algorithm is contractive w.r.t. a carefully designed Kantorovich (L1 Wasserstein) distance. The lower bound for the contraction rate is explicit.

Model of a three-qubit cluster in a thermal bath
Физико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2023 This work studies a mathematical model of a quantum cluster consisting of three qubits and being in thermal equilibrium with the environment. The effective Hamiltonian is invariant under permutations of qubits and consists of two parts. The first part is

Determining a local Hamiltonian from a single eigenstate [PDF]
Quantum, 2017 We ask whether the knowledge of a single eigenstate of a local Hamiltonian is sufficient to uniquely determine the Hamiltonian. We present evidence that the answer is ``yes" for generic local Hamiltonians, given either the ground state or an excited ...

Discussiones Mathematicae Graph Theory, 2015 For integers k and n with 2 ≤ k ≤ n − 1, a graph G of order n is k-path pancyclic if every path P of order k in G lies on a cycle of every length from k + 1 to n. Thus a 2-path pancyclic graph is edge-pancyclic.

Some properties of the generalized sierpiński gasket graphs [PDF]
Transactions on CombinatoricsThe generalized Sierpiński gasket graphs $S[G,t]$ are introduced as the graphs obtained from the Sierpiński graphs $S(G,t)$ by contracting single edges between copies of previous phases.
