Planar and Pyramidal Pentacoordinate Selenium Atoms

Chemistry – A European Journal, EarlyView.
Planar (D5h) and pyramidal (C5v) dianionic clusters, SeM5X52− (M = LiK; X = FBr), showcase pentacoordinate selenium atoms stabilized by geometric confinement and electrostatic interactions with surrounding alkali and halogen atoms. Abstract A systematic computational exploration of the dianionic systems SeM5X52− (M = Li─Cs; X = F─I) was conducted to ...

Bio‐Based Amphiphilic Farnesyl Glycidyl Ether Block Copolymers: Aqueous Self‐Assembly and Solubilization Boosting

Chemistry – A European Journal, EarlyView.
Bio‐derived amphiphilic poly(ethylene glycol)‐b‐poly(terpenyl glycidyl ether) diblock copolymers (mPEG114‐b‐PTGEm) were synthesized via AROP from farnesyl glycidyl ether (FarGE) and its hexahydrogenated derivative (HHFarGE). Block copolymer amphiphilicity is easily tunable via the TGE block size m and systematically affects the critical micelle ...

Real-space renormalization group approach for the corner Hamiltonian

, 2005
We present a real-space renormalization group approach for the corner Hamiltonian, which is relevant to the reduced density matrix in the density matrix renormalization group.

Equivariant toric geometry and Euler–Maclaurin formulae

Communications on Pure and Applied Mathematics, EarlyView.
Abstract We first investigate torus‐equivariant motivic characteristic classes of toric varieties, and then apply them via the equivariant Riemann–Roch formalism to prove very general Euler–Maclaurin‐type formulae for full‐dimensional simple lattice polytopes.

Scalar-Tensor gravity with system-dependent potential and its relation with Renormalization Group extended General Relativity

, 2015
We show that Renormalization Group extensions of the Einstein-Hilbert action for large scale physics are not, in general, a particular case of standard Scalar-Tensor (ST) gravity.

Ghost effect from Boltzmann theory

Communications on Pure and Applied Mathematics, EarlyView.
Abstract Taking place naturally in a gas subject to a given wall temperature distribution, the “ghost effect” exhibits a rare kinetic effect beyond the prediction of classical fluid theory and Fourier law in such a classical problem in physics. As the Knudsen number ε$\varepsilon$ goes to zero, the finite variation of temperature in the bulk is ...

Renormalization Group and Probability Theory

, 2000
The renormalization group has played an important role in the physics of the second half of the twentieth century both as a conceptual and a calculational tool.

Estimation of the GCV of Coal Using Real‐Time Plant Data

Energy Science &Engineering, EarlyView.
ABSTRACT Online or real‐time strategies of estimating the gross calorific value (GCV) of coal are still not fully explored in academic literature, even though both conventional and sophisticated offline methods for estimating the GCV are well described.

Relativistic low-momentum interactions from renormalization group

Physics Letters B
The relativistic Vlowk is developed from a renormalization group method for the first time, to provide softened NN interactions for relativistic abinitio calculations. Starting from a given bare NN interaction, the renormalization group method eliminates
