Controlled cluster expansion at a Zintl cluster surface [PDF]
Angewandte Chemie, 2023 AbstractReaction of the tris‐hypersilyl nonagermanide Zintl cluster salt, K[Ge9(Hyp)3] (Hyp=Si(SiMe3)3) with [Rh(η2,η2‐L)Cl]2 (L=1,5‐cyclooctadiene, COD; norbornadiene, NBD) afforded eleven‐ and twelve‐vertex homo‐multimetallic clusters by cluster core expansion.

A joint Cluster and ground-based instruments study of two magnetospheric substorm events on 1 September 2002 [PDF]
Annales Geophysicae, 2004 We present a coordinated ground- and space-based multi-instrument study of two magnetospheric substorm events that occurred on 1 September 2002, during the interval from 18:00 UT to 24:00 UT.

Cluster Expansion in the Canonical Ensemble [PDF]
Communications in Mathematical Physics, 2012 We consider a system of particles confined in a box $\La\subset\R^d$ interacting via a tempered and stable pair potential. We prove the validity of the cluster expansion for the canonical partition function in the high temperature - low density regime. The convergence is uniform in the volume and in the thermodynamic limit it reproduces Mayer's virial ...

Cluster expansion for ground states of local Hamiltonians [PDF]
Nuclear Physics B, 2016 A central problem in many-body quantum physics is the determination of the ground state of a thermodynamically large physical system. We construct a cluster expansion for ground states of local Hamiltonians, which naturally incorporates physical ...

Linear Atomic Cluster Expansion Force Fields for Organic Molecules: Beyond RMSE. [PDF]
J Chem Theory Comput, 2021 We demonstrate that fast and accurate linear force fields can be built for molecules using the Atomic Cluster Expansion (ACE) framework. The ACE models parametrize the Potential Energy Surface in terms of body ordered symmetric polynomials making the ...

Multilayer atomic cluster expansion for semilocal interactions
Physical Review Research, 2022 Traditionally, interatomic potentials assume local bond formation supplemented by long-range electrostatic interactions when necessary. This ignores intermediate-range multiatom interactions that arise from the relaxation of the electronic structure ...

A cluster expansion for dipole gases [PDF]
Physica A: Statistical Mechanics and its Applications, 1998 We give a new proof of the well-known upper bound on the correlation function of a gas of non-overlapping dipoles of fixed length and discrete orientation working directly in the charge representation, instead of the more usual sine-Gordon representation.

Entropy, 2019 Configuration entropy is believed to stabilize disordered solid solution phases in multicomponent systems at elevated temperatures over intermetallic compounds by lowering the Gibbs free energy.
