Derivation of Coupled KPZ Equations from Interacting Diffusions Driven by a Single-Site Potential
The Kardar-Parisi-Zhang (KPZ) equation is a stochastic partial differential equation which is derived from various microscopic models, and to establish a robust way to derive the KPZ equation is a fundamental ...

Open AccessThe Emergence of Order in Many Element Systems
Our work is dedicated to the introduction and investigation of a new asymptotic correlation relation in the field of mean field models and limits. This new notion, order (as opposed to chaos), revolves around ...

Pseudo-potential Lattice Boltzmann Method with an Improved Forcing Scheme for the Cumulant Collision Model
This paper proposes an improved cumulant collision model for the pseudo-potential lattice Boltzmann method (LBM) to increase the stability of multiphase flow simulations involving low viscosities. This model i...

Open AccessXstar atomic database: the PyXstar package
We present a progress report on the development of PyXstar, a Python package to manage the data (input, output, intermediate, atomic database, and model-grids) associated with the xstar code for treating photoion...

On Resistance Distance and Kirchhoff Index of Cacti Networks
Resistance distance in electrical circuits measures how much a component or an entire circuit resists the flow of electric current. When dealing with intricate circuits, this term explicitly denotes the total ...

Nature Abhors a Vacuum: A Simple Rigorous Example of Thermalization in an Isolated Macroscopic Quantum System
We show, without relying on any unproven assumptions, that a low-density free fermion chain exhibits thermalization in the following (restricted) sense. We choose the initial state as a pure state drawn random...

Controlled-joint remote implementation of operators and its possible generalization
The existing notion of the shared entangled state-assisted remote preparation of unitary operator (equivalently the existing notion of quantum remote control) using local operation and classical communication ...

Study of multi-solitons, breather structures in dusty plasma with generalized polarization force
A theoretical inquiry delves into the presence of multiple solitons and breather configurations within a nonuniform, inhomogeneous, unmagnetized dusty plasma characterized by universally polarized force. This ...

Quantum phase transition and entanglement entropy in the Dicke model with a squeezed light
Superradiant phase transition and entanglement entropy in the Dicke model with a squeezed light are investigated. We find a special rotation coordinate system map** the original Hamiltonian into an effective...

The High-Order Corrections of Discrete Harmonic Measures and Their Correction Constants
By the dimension reduction idea, overshoot for random walks, coupling and martingale arguments, we obtain a simpler and easily computable expression for the first-order correction constant between discrete har...

Open AccessDriving voltage frequency and electrode material effects on electromagnetic radiation of the surface dielectric barrier discharge in the air
The electrical discharges are, among others, accompanied by the emission of electromagnetic waves of various frequencies. We studied this emission for the surface dielectric barrier discharge in the air. We us...

Influence of bias voltage rise time, pressure and magnetic field on the boundary layer time evolution of a thermal collisional magnetized plasma in plasma immersion ion implantation
The formation and temporal evolution of the plasma boundary layer in plasma immersion ion implantation is investigated in the presence of a magnetic field. It is assumed that the ions are thermalized. When a h...

In-situ deposition of silver nanoparticles onto glass by non-thermal plasma jet
In this study, we employed an atmospheric-pressure non-thermal plasma jet that used silver nitrate solution as the precursor which is injected, in an aerosol state, into the plasma jet to create silver nanopar...

Open AccessA FAC potential for autostructure
We describe the implementation of the current Flexible Atomic Code (FAC) unique electron central potential within the autostructure code. We show that the two codes then give the same atomic data for all practica...

Absence of Shift-Invariant Gibbs States (Delocalisation) for One-Dimensional \(\pmb {\mathbb {Z}}\) -Valued Fields With Long-Range Interactions
We show that a modification of the proof of our paper Coquille et al. (J. Stat. Phys. 172(5), 1210–1222 (2018)), in the spirit of Fröhlich and Pfister (Commun. Math. Phys. 81, 277–298 (1981)), shows delocalisatio...
