This study reexamines the excitation of ion-acoustic precursor solitons by a supersonically moving charged debris object, incorporating two previously overlooked physical factors:…
Tight-binding and density-functional study of the Raman tensor in two-dimensional massive Dirac fermion systems
Selçuk Parlak, Abhishek Kumar, Runhan Li +2
Recently, two unusual features were theoretically predicted for the Raman response of out-of-plane phonons in magnetic two-dimensional materials hosting massive Dirac fermions. Fir…
Two-Stream Instability and Bernstein-Greene-Kruskal Mode Formation in Coulomb One Component Plasma
Ajaz Mir, Rauoof Wani, Sanat Tiwari +1
We investigate the Two-Stream Instability in a strongly coupled plasma using classical molecular dynamics simulations with long-range Coulomb interactions between particles. The no…
Optimal Thermalization under Indefinite Causal Order with Identical and Asymmetric Baths
Neeraj Sharma, Parveen Kumar
Indefinite causal order (ICO), in which the order of quantum operations is placed in a coherent superposition, has been demonstrated to enhance various information-processing tasks…
The nature of ASASSN-24fw's occultation: modelling the event as dimming by optically thick rings around a sub-stellar companion
Sarang Shah, Jonathan P. Marshall, Carlos del Burgo +12
ASASSN-24fw is a main-sequence F-type star that experienced a rapid and long-lasting dimming event beginning in late 2024 and continuing until mid 2025. Its pre-dimming spectral en…
Interface crossing behavior of prolate microswimmers: thermo and hydrodynamics
Rishish Mishra, Harish Pothukuchi, Harinadha Gidituri +1
Motivated by recent experiments of motile bacteria crossing liquid-liquid interfaces of isotropic- nematic coexistence (Cheon et al., Soft Matter 20: 7313-7320, 2024), we study the…
Inflated hot Jupiters: Inferring average atmospheric velocity via Ohmic models coupled with internal dynamo evolution
Daniele Viganò, Soumya Sengupta, Clàudia Soriano-Guerrero +4
The inflated radii observed in hundreds of hot Jupiters (HJ) represent a long-standing open issue. In this study, we quantitatively investigate this phenomenon within the framework…
Nonlinear Mixing of Waves in a Yukawa One Component Plasma
Ajaz Mir, Farida Batool, Sanat Tiwari +1
The phenomenon of nonlinear wave mixing is investigated in a Yukawa one-component plasma using two-dimensional classical Langevin molecular dynamics simulations. The wave spectrum…
-analogues of Fisher's inequality and oddtown theorem
Hiranya Kishore Dey
A classical result in design theory, known as Fisher's inequality, states that if every pair of clubs in a town shares the same number of members, then the number of clubs cannot e…
Regularity of -Path Ideals of Trees and Unicyclic Graphs
Rajiv Kumar, Rajib Sarkar
Let be a simple graph and be its -path ideal in the corresponding polynomial ring . In this article, we prove that for an arbitrary graph , is…
Permutation polynomials over finite fields from low-degree rational functions

This paper considers permutation polynomials over the finite field in even characteristic by utilizing low-degree permutation rational functions over . As a result,…
Bivariate local permutation polynomials, their companions, and related enumeration results
Sartaj Ul Hasan, Ramandeep Kaur, Hridesh Kumar
We construct a new family of permutation group polynomials over finite fields of arbitrary characteristic, which are special types of bivariate local permutation polynomials. For t…
Toeplitz, Hankel, de Branges and two truncated matrix moment problems
Kousik Dhara, Harry Dym
This paper deals with (1) the truncated matrix Hamburger moment problem from the point of view of reproducing kernel Hilbert spaces of vector valued entire functions of the kind in…
Towards Robust Knowledge Representations in Multilingual LLMs for Equivalence and Inheritance based Consistent Reasoning
Gaurav Arora, Srujana Merugu, Shreya Jain +1
Reasoning and linguistic skills form the cornerstone of human intelligence, facilitating problem-solving and decision-making. Recent advances in Large Language Models (LLMs) have l…
Some new classes of permutation polynomials and their compositional inverses
Sartaj Ul Hasan, Ramandeep Kaur
We focus on the permutation polynomials of the form $L(X)+\Tr_{m}^{3m}(X)^{s}$ over $\F_{q^3}$, where $\F_q$ is the finite field with elements, is a prime number, i…
Evaporation limited spreading of ethanol on rectangular porous strips: an experimental and theoretical investigation
Rampally Srirama Chandra Murthy, Navneet Kumar
Wicking is a widely studied process in both natural and artificial systems. In many industrial applications, such as heat pipes, the wicking liquid evaporates to regulate temperatu…
The revised boomerang connectivity tables and their connection to the Difference Distribution Table
Kirpa Garg, Sartaj Ul Hasan, Constanza Riera +1
It is well-known that functions over finite fields play a crucial role in designing substitution boxes (S-boxes) in modern block ciphers. In order to analyze the security of an S-b…
