A note on lifespan estimates for higher-order parabolic equations

Nurdaulet N. Tobakhanov, Berikbol T. Torebek

We investigate the lifespan of solutions to the higher-order semilinear parabolic equation $u_{t} + (- Δ)^{m} u = ∣ u ∣^{p}, x \in R^{n}, t > 0$ with initial data. We focus on the…

Thermal properties of Klein-Gordon Oscillator in the Context of Amelino-Camelia and Magueijo-Smolin Doubly Special Relativity (DSR) frameworks

Abdelmalek Boumali, Nosratollah Jafari, Bekdaulet Shukirgaliyev +1

We examine the thermal and statistical properties of the one dimensional Klein-Gordon oscillator within two prominent Doubly Special Relativity (DSR) frameworks: Amelino-Camelia an…

RIS-Assisted Physical Layer Security: Artificial Noise-Driven Optimization and Measurements

Ahmet Muaz Aktas, Sefa Kayraklik, Sultangali Arzykulov +3

Reconfigurable intelligent surface (RIS) has emerged as a key enabler for providing signal coverage, energy efficiency, reliable communication, and physical layer security (PLS) in…

Assessing the Distance for Probing the Nuclear Equation of State with Supernova Gravitational Waves

Y. Sultan Abylkairov, Matthew C. Edwards, Artyom Ostrikov +6

Gravitational waves from core-collapse supernovae provide a unique probe of the equation of state (EOS) of high density matter. In this work, we focus on the bounce signal from num…

Dynamical model of Praesepe and its tidal tails

L. Weis, C. West, A. Just +5

Context. The dynamical evolution of open clusters in the tidal field of the Milky Way and the feeding of the disc field star population depend strongly on the initial conditions at…

Zak Phase Dislocations in Trimer Lattices

Tileubek Uakhitov, Abdybek Urmanov, Serik E. Kumekov +1

Wave propagation in periodic media is governed by energy-momentum relation and geometric phases characterizing band topology, such as Zak phase in one-dimensional lattices. We demo…

Particle creation from entanglement entropy

Michael R. R. Good, Evgenii Ievlev, Eric V. Linder

We investigate how entanglement entropy can drive particle creation, deriving explicit relations between entropy and the radiated particle spectrum, the total number of particles,…

A non-computable c.e. closed subset of $[0, 1]$

Serikzhan Badaev, Nikolay Bazhenov, Sergey Goncharov +2

We prove that there exists a $Σ_{1}^{0}$ closed subset of $[0, 1]$ that is not homeomorphic to any computably compact space. We show that the index set of c.e. subspaces of $[0, 1]$ that…

Quadrupole-hexadecapole coupling in the rare earth region with beyond mean field correlations

R. Rodriguez-Guzman, L. M. Robledo

The roles of static hexadecapole deformation and beyond-mean-field quadrupole-hexadecapole configuration mixing are studied for a selected set of Yb, Hf, W and Os isotopes within t…

Evolution of star clusters with initial bulk rotation via N-body simulations

Abylay Bissekenov, Xiaoying Pang, Albrecht Kamlah +6

Young star clusters can inherit bulk rotation from the molecular clouds from which they have formed. This rotation can affect the long-term evolution of a star cluster and its cons…

Centrally concentrated star formation in young clusters

Adilkhan Assilkhan, Mordecai-Mark Mac Low, Brooke Polak +6

The study of star cluster evolution necessitates modeling how their density profiles develop from their natal gas distribution. Observational evidence indicates that many star clus…

Infalling ultra-faint dwarfs as emissaries of the Axiverse

A. Pozo, T. Broadhurst, H. N. Luu +8

Recent discoveries of ultra-faint dwarf galaxies (UFDs) infalling onto the Milky Way, namely Leo K \& M at $r ≃ 450$ kpc, considerably strengthens the case that UFDs constitute…

The informativeness of the gradient revisited

Rustem Takhanov

In the past decade gradient-based deep learning has revolutionized several applications. However, this rapid advancement has highlighted the need for a deeper theoretical understan…

Through the Looking-Glass, and What AdS Found There: quantum particle production with a Whittaker spectrum

Michael R. R. Good, Eric V. Linder

Parity-inverted anti-de Sitter space -- ``flipped AdS'' -- is studied through the accelerating boundary correspondence of a moving mirror trajectory. The particle production exhibi…

Cloud-cloud collision and star formation in G013.313+0.193

Dilda Berdikhan, Jarken Esimbek, Christian Henkel +18

We study the G013.313+0.193 G013.313 region, a complex environment characterized by molecular cloud interactions indicative of cloud-cloud collision (CCC). Observations of the NH3(…

Cosmic Acceleration from Nothing

Michael R. R. Good, Eric V. Linder

We demonstrate that if the universe started as a vacuum fluctuation rather than from a singular Big Bang state, the universe must have a late-time cosmic acceleration. This is requ…

How to obtain slow roll inflation driven by non-linear electrodynamics

Daniele Malafarina, Hrishikesh Chakrabarty, Ilia Musco

We establish for the first time the conditions that must be imposed on the action for a magnetic universe in a theory of non-linear electrodynamics in order to have an asymptotical…
