Post-Wick theorems for symbolic manipulation of second-quantized expressions in atomic many-body perturbation theory [PDF]

open access: yes, 2009
Manipulating expressions in many-body perturbation theory becomes unwieldily with increasing order of the perturbation theory. Here I derive a set of theorems for efficient simplification of such expressions.

Algorithmic Design of Disordered Networks With Arbitrary Coordination: Application to Biophotonics

open access: yesAdvanced Functional Materials, EarlyView.
Predictive Design of Disordered Networks: Disordered network‐like morphologies are abundant in nature, from cytoskeletal networks to bone structures and chalcogenide glasses. These structures are naturally hard to characterize. A new algorithmic tool extends the established Wooten–Weaire–Winer (WWW) algorithm to valencies above 4.

Nanotherapies for Atherosclerosis: Targeting, Catalysis, and Energy Transduction

open access: yesAdvanced Healthcare Materials, EarlyView.
Atherosclerosis management is hindered by poor drug targeting and plaque heterogeneity. Nanotechnology overcomes these barriers via three core strategies: (1) target‐engineered nanocarriers that achieve lesion‐specific precision via ligand modification, biomimetic camouflage, stimuli‐responsive release, and self‐propelling nanomotors; (2) catalytic ...

Multicritical continuous random trees

open access: yes, 2006
We introduce generalizations of Aldous' Brownian Continuous Random Tree as scaling limits for multicritical models of discrete trees. These discrete models involve trees with fine-tuned vertex-dependent weights ensuring a k-th root singularity in their ...

Quantization of gauge fields, graph polynomials and graph cohomology [PDF]

open access: yes, 2013
We review quantization of gauge fields using algebraic properties of 3-regular graphs. We derive the Feynman integrand at n loops for a non-abelian gauge theory quantized in a covariant gauge from scalar integrands for connected 3-regular graphs ...

Certain classes of meromorphically P-valent starlike functions

open access: yesApplied Mathematics Letters, 1994
Let \(\sum_ p\) denote the class of functions \(f(z) = \sum^ \infty_{k = - p} a_{k + p - 1} z^ k\) with \((a_{-1}=1)\) which are analytic for ...

Mixed‐Metal Promotion in a Manganese‐Molybdenum Oxynitride as Catalyst to Integrate C─C and C─N Coupling Reactions for the Direct Synthesis of Acetonitrile from Syngas and Ammonia

open access: yesAdvanced Materials, EarlyView.
Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.

Effects of electron transfer on the stability of hydrogen bonds. [PDF]

open access: yes, 2017
The measurement of the dimerization constants of hydrogen-bonded ruthenium complexes (12, 22, 32) linked by a self-complementary pair of 4-pyridylcarboxylic acid ligands in different redox states is reported.
