Higher-Order Network Representation of J. S. Bach's Solo Violin Sonatas and Partitas: Topological and Geometrical Explorations
Music is inherently complex, with structures and interactions that unfold across multiple layers. Complex networks have emerged as powerful structures for the quantitative analysis of Western classical music, revealing significant features of its harmonic and structural organization. Although notable works have used these approaches to study music, dyadic representations of interactions fall short in conveying the underlying complexity and depth. In recent years, the limitations of traditional …

Dynamical thermalization, Rayleigh-Jeans condensate, vortexes and wave collapse in quantum chaos fibers and fluid of light
We study analytically and numerically the time evolution of a nonlinear field described by the nonlinear Schrödinger equation in a chaotic $D$-shape billiard. In absence of nonlinearity the system has standard properties of quantum chaos. This model describes a longitudinal light propagation in a multimode D-shape optical fiber and also those in a Kerr nonlinear medium of atomic vapor. We show that, above a certain chaos border of nonlinearity, chaos leads to dynamical thermalization with the …

Spatio-Temporal Weak Measurement of Chiral Ultra short Laser Pulse
We present a comprehensive study on the spatio temporal weak measurement of a chiral ultrafast optical pulse. We create a chiral vector wave packet by transmitting ultrashort laser pulse via a birefringent or magneto-optic medium. Employing time-resolved leakage radiation microscopy, we examine how the real and imaginary components of the weak value parameter ($ε$) influence pulse propagation over time. Our technique allows us to detect and categorize the temporal polarization fluctuation in a…

Some features in 4-level generation in LIPLs
This paper shows that in Laser-Induced Plasma Lasers (LIPL), the collisionally assisted transitions that lead to the inversion population on an upper-generation level E_up may be partly forbidden. The spin-orbit coupling may increase the oscillator strength of such transitions. It also demonstrates that collisions between electrons and excited atoms can strongly increase the atoms' energy, creating a population inversion at the E_up level, which may lie about 1 eV above the …

Interior of a black hole in the framework of the scalar quasiparticle model
We have developed an effective thermodynamic model for a black hole's interior composed of scalar quasiparticles. The proposed interior consists of a core and a crust; the properties of both depend on the kinetics of the quasiparticles. In the core, the quasiparticles possess zero classical kinetic energy; the total potential energy $U(N)$ of the core depends only on the number $N$ of quasiparticles inside it. The thermodynamic description of this state of matter requires the introduction of an…

New Magnetic Temperature Non-Contact Sensor
Non-contact temperature sensors are widely used, often utilizing infrared light for temperature measurement. However, specific applications demand non-contact detection, particularly within closed containers containing fluids or gases, where optical methods are unsuitable. Our approach is designed precisely for this purpose. We conducted measurements, introduced a prototype of our detector, and confirmed its compatibility with nonmagnetic containers.

Anisotropic conformal Carroll field theories and their gravity duals
We investigate anisotropic conformal Carroll field theories and their holographic duals. On the field theory side, we focus on the case with scaling exponent $z=0$ in two and three spacetime dimensions. These theories exhibit infinite-dimensional symmetry algebras, including supertranslations and superrotations, and are closely related to, but distinct from, Warped Conformal Field Theories. We construct the associated Carrollian stress tensor, derive its transformation properties, and analyse t…
