text: African cichlids display a remarkable assortment of jaw morphologies, pigmentation
patterns, and mating behaviors. In addition to this previously documented diversity,
recent studies have documented a rich diversity of sex chromosomes within these
fishes. Here we review the known sex-determination network within vertebrates,
and the extraordinary number of sex chromosomes systems segregating in African
cichlids. We also propose a model for understanding the unusual number of sex
chromosome systems within this clade.

text: The thermodynamic description of many-particle systems rests on the assumption
of ergodicity, the ability of a system to explore all allowed configurations in
the phase space. Recent studies on many-body localization have revealed the existence
of systems that strongly violate ergodicity in the presence of quenched disorder.
Here, we demonstrate that ergodicity can be weakly broken by a different mechanism,
arising from the presence of special eigenstates in the many-body spectrum that
are reminiscent of quantum scars in chaotic non-interacting systems. In the single-particle
case, quantum scars correspond to wavefunctions that concentrate in the vicinity
of unstable periodic classical trajectories. We show that many-body scars appear
in the Fibonacci chain, a model with a constrained local Hilbert space that has
recently been experimentally realized in a Rydberg-atom quantum simulator. The
quantum scarred eigenstates are embedded throughout the otherwise thermalizing
many-body spectrum but lead to direct experimental signatures, as we show for
periodic recurrences that reproduce those observed in the experiment. Our results
suggest that scarred many-body bands give rise to a new universality class of
quantum dynamics, opening up opportunities for the creation of novel states with
long-lived coherence in systems that are now experimentally realizable.

text: We study the Fokker-Planck equation derived in the large system limit of the
Markovian process describing the dynamics of quantitative traits. The Fokker-Planck
equation is posed on a bounded domain and its transport and diffusion coefficients
vanish on the domain's boundary. We first argue that, despite this degeneracy,
the standard no-flux boundary condition is valid. We derive the weak formulation
of the problem and prove the existence and uniqueness of its solutions by constructing
the corresponding contraction semigroup on a suitable function space. Then, we
prove that for the parameter regime with high enough mutation rate the problem
exhibits a positive spectral gap, which implies exponential convergence to equilibrium.Next,
we provide a simple derivation of the so-called Dynamic Maximum Entropy (DynMaxEnt)
method for approximation of observables (moments) of the Fokker-Planck solution,
which can be interpreted as a nonlinear Galerkin approximation. The limited applicability
of the DynMaxEnt method inspires us to introduce its modified version that is
valid for the whole range of admissible parameters. Finally, we present several
numerical experiments to demonstrate the performance of both the original and
modified DynMaxEnt methods. We observe that in the parameter regimes where both
methods are valid, the modified one exhibits slightly better approximation properties
compared to the original one.

text: We developed a method to calculate two-photon processes in quantum mechanics
that replaces the infinite summation over the intermediate states by a perturbation
expansion. This latter consists of a series of commutators that involve position,
momentum, and Hamiltonian quantum operators. We analyzed several single- and many-particle
cases for which a closed-form solution to the perturbation expansion exists, as
well as more complicated cases for which a solution is found by convergence. Throughout
the article, Rayleigh and Raman scattering are taken as examples of two-photon
processes. The present method provides a clear distinction between the Thomson
scattering, regarded as classical scattering, and quantum contributions. Such
a distinction lets us derive general results concerning light scattering. Finally,
possible extensions to the developed formalism are discussed.

text: We establish the existence of a global solution for a new family of fluid-like
equations, which are obtained in certain regimes in as the mean-field evolution
of the supercurrent density in a (2D section of a) type-II superconductor with
pinning and with imposed electric current. We also consider general vortex-sheet
initial data, and investigate the uniqueness and regularity properties of the
solution. For some choice of parameters, the equation under investigation coincides
with the so-called lake equation from 2D shallow water fluid dynamics, and our
analysis then leads to a new existence result for rough initial data.
