Since we cannot measure the function n(x) directly in experimental crowds, we instead consider discrete counts of individuals within equal area bins (quadrats)26. Thus, to make contact with experiments we discretize Eq. 1 as \(H = \mathop {\sum}\nolimits_b \left( {f_{N_b} + v_bN...
[5]ρ(r)=∑gi|ψi(r)|2 wheregiis the occupation of theith one-particle molecular orbitalψi(r) and the sum is over all mutually orthonormal occupied orbitals. The density obtained from this expression is also known as the charge density. Unlike the many-electron wave function, which is...
The differences in ribozyme activity observed in condensates containing (RGG)4and the other peptides suggests locally distinct physicochemical properties that modulate ribozyme activity. To explore this further, we first analysed RNA and peptide mobility in coacervates by fluorescence recovery after photoble...
where n is the particle density in the system, then the sum ∑p in (19) may be approximated by unity. Accordingly, the partition function of the system would become, see equation (17), (21)QN(V,T)≡Tr(e-βH^)≈1N!λ3N∫1(d3Nr)=1N!(Vλ3)N. This is precisely the result obt...
Since the principal system is entangled with the environment in an open quantum system, it is usually described by a mixed state rather than a pure state of the wave function. On this occasion, the following advantages of the state density matrix are demonstrated: • The density matrix can ...

hermiter is an R package that facilitates the estimation of the probability density function and cumulative distribution function in univariate and bivariate settings using Hermite series based estimators. In addition, hermiter allows the estimation of the quantile function in the univariate case and non...
along with the relative energy errors for DFT compared to CC for each conformer (bottom). Note that the DFT energy errors are not a simple function of the energy relative to the minimum energy geometry (see Supplementary Fig.2), as short O–H bond lengths tend to be too high in energy...
In this work, we propose DeepH-E3, a universal E(3)-equivariant deep-learning framework to represent the spin–orbital DFT Hamiltonian\({\hat{H}}_{{{\rm{DFT}}}\)as a function of atomic structure\(\{{{\mathcal{R}}}\}\)by neural networks, which enables efficient electronic structure...
