Bulk detection of time-dependent topological transitions in quenched chiral models [PDF]
Physical Review Research, 2020 The topology of one-dimensional chiral systems is captured by the winding number of the Hamiltonian eigenstates. Here we show that this invariant can be read out by measuring the mean chiral displacement of a single-particle wave function that is ...

Boost-invariant mean field approximation and the nuclear Landau-Zener effect [PDF]
, 2007 We investigate the relation between time-dependent Hartree-Fock (TDHF) states and the adiabatic eigenstates by constructing a boost-invariant single-particle Hamiltonian.

Asymptotics of the invariant measure in mean field models with jumps
Stochastic Systems, 2012 We consider the asymptotics of the invariant measure for the process of the empirical spatial distribution of N coupled Markov chains in the limit of a large number of chains. Each chain reflects the stochastic evolution of one particle.

Translation invariant state and its mean entropy-I [PDF]
, 2017 Let $\IM =\otimes_{n \in \IZ}\!M^{(n)}(\IC)$ be the two sided infinite tensor product $C^*$-algebra of $d$ dimensional matrices $\!M^{(n)}(\IC)=\!M_d(\IC)$ over the field of complex numbers $\IC$.

On the Beckenbach–Gini–Lehmer Means and Means Mappings
Mathematics, 2020 Beckenbacg–Gini–Lehmer type means and mean-type mappings generated by functions of several variables, for which the arithmetic mean is invariant, are introduced.

$\mathcal{T}_{M}$-Amenability of Banach Algebras [PDF]
Sahand Communications in Mathematical AnalysisWe introduce the notions of $\mathcal{T}_{M}$-amenability and $\phi$-$\mathcal{T}_{M}$-amenability. Then, we characterize $\phi$-$\mathcal{T}_{M}$-amenability in terms of $WAP$-diagonals and $\phi$-invariant means. Some concrete cases are also discussed.

Permutation Invariant Feature Extraction Method Based on Affinity Matrix of Point Cloud [PDF]
Jisuanji gongcheng, 2022 The applicationofpoint cloud recognition and segmentation requires the extraction ofthe spatial rotation invariant and permutation invariant features of the point cloud.PointCNN extracts these features by supervised learning, but this requires additional

An amenability-like property of finite energy path and loop groups
Comptes Rendus. Mathématique, 2021 We show that the groups of finite energy loops and paths (that is, those of Sobolev class $H^1$) with values in a compact connected Lie group, as well as their central extensions, satisfy an amenability-like property: they admit a left-invariant mean on ...

A Bi-Invariant Statistical Model Parametrized by Mean and Covariance on Rigid Motions
Entropy, 2020 This paper aims to describe a statistical model of wrapped densities for bi-invariant statistics on the group of rigid motions of a Euclidean space. Probability distributions on the group are constructed from distributions on tangent spaces and pushed to
