Extracting kinetic information from short-time trajectories: relaxation and disorder of lossy cavity polaritons. [PDF]
Abstract The emerging field of molecular cavity polaritons has stimulated a surge of experimental and theoretical activities and presents a unique opportunity to develop the many‐body simulation methodology. This paper presents a numerical scheme for the extraction of key kinetic information of lossy cavity polaritons based on the transfer tensor ...

Liouvillian First Integrals for Generalized Liénard Polynomial Differential Systems [PDF]
Abstract We study the Liouvillian first integrals for the generalized Liénard polynomial differential systems of the form xʹ = y, yʹ = -g(x) - f(x)y, where g(x) and f(x) are arbitrary polynomials such that 2 ≤ deg g ≤ deg f.

Geometry and integrability of quadratic systems with invariant hyperbolas
Let QSH be the family of non-degenerate planar quadratic differential systems possessing an invariant hyperbola. We study this class from the viewpoint of integrability.

Liouvillian and Analytic First Integrals for the Brusselator System [PDF]
We characterize the Liouvillian and analytic first integrals for the polynomial differential systems of the form x' = a − (b + 1)x + x2y, y' = bx − x2y, with a, b ∈ R, called the Brusselator differential systems.

Liouvillian First Integrals for Generalized Riccati Polynomial Differential Systems [PDF]
Abstract We study the existence and non-existence of Liouvillian first integrals for the generalized Riccati polynomial differential systems of the form xʹ = y, yʹ = a(x)y2 +b(x)y+c(x), where a(x), b(x) and c(x) are polynomials.

Liouvillian first integrals for quadratic systems with an integrable saddle [PDF]
Agraïments: The second author was supported by Portuguese National Funds through FCT - Fundacâo para a Ciência e a Tecnologia within the project PTDC/MAT/117106/2010 and by CAMGSD. We provide explicit expressions for the Liouvillian first integrals of the quadratic polynomial differential systems having an integrable saddle.

Transition Characteristics of Non‐Hermitian Skin Effects in a Zigzag Lattice Without Chiral Symmetry
Transitions of the non‐Hermitian skin effect in a Zigzag lattice with/without chiral symmetry are closely linked to the real parts of eigen‐energy spectra when the closed eigen‐energy spectra under periodic boundary condition have no interior. Such an approach provides a way in judging transitions of localized directions and has a potential in helping ...

Modeling spin relaxation in complex radical systems using MolSpin
Bloch–Redfield–Wangsness theory is a powerful mathematical framework to describe environment‐induced spin relaxation. In particular, complex perturbations which have no explicit analytical form can be included with this theory. The generalized implementation into the toolkit MolSpin guarantees a versatile usage with which complex motions such as those ...

Branching High‐Order Exceptional Points in Non‐Hermitian Optical Systems
Exceptional points are complex‐valued spectral singularities that lead to a host of intriguing features such as loss‐induced transparency—a counterintuitive process in which an increase in the system's overall loss can lead to enhanced transmission.

Liouvillian first integrals for Liénard polynomial differential systems [PDF]
Summary: We characterize the Liouvillian first integrals for the Liénard polynomial differential systems of the form \(x^{\prime } = y, y^{\prime } = -cx-f(x)y\), with \(c \in \mathbb{R}\) and \(f(x)\) is an arbitrary polynomial. For obtaining this result we need to find all the Darboux polynomials and the exponential factors of these systems.
