Generalized BChS Model with Group Interactions: Shift in the Critical Point and Mean-Field Ising Universality

Amit Pradhan · 2026

We introduce a generalized version of the Biswas-Chatterjee-Sen (BChS) model \cite{Biswas} with group interactions of size $q$, extending the original pairwise interaction dynamics. Within a mean-fiel…

The role of the density of states in Bose-Einstein condensation

Alexios P. Polychronakos, Stephane Ouvry · 2025

The onset of Bose-Einstein condensation in systems with { various} densities of states is examined, with particular attention to the role of the behavior of their {energy} spectrum at low and high ene…

Quantized Axial Charge in the Hamiltonian Approach to Wilson Fermions

Tatsuya Yamaoka · 2025

We investigate the Hamiltonian formulation of 1+1~D staggered fermions and reconstruct vector and axial charge operators, found by Arkya Chatterjee et al., using the Wilson fermion formalism. These op…

Exponential correction to Friedmann equations

Ozgur Okcu, Ekrem Aydiner · 2024

In this paper, employing the exponential corrected entropy (Chatterjee and Ghosh in Phys Rev Lett 125:041302, 2020), we derive the modified Friedmann equations from the first law of thermodynamics at …

Photospheric Lorentz force changes in eruptive and confined solar flares

Samriddhi Sankar Maity, Ranadeep Sarkar, Piyali Chatterjee, Nandita Srivastava · 2023

Solar flares are known to leave imprints on the magnetic field at the photosphere, often manifested as an abrupt and permanent change in the downward-directed Lorentz force in localized areas inside t…

First-order formalism for Alice string

E. Acalapati, H. S. Ramadhan · 2023

We apply the {\it first-order formalism} method to obtaining BPS equations for Alice string. This is done by generalizing the well-known first-order formalism to the case of non-Abelian strings. We do…

A Note on the Post-Quantum Security of (Ring) Signatures

Rohit Chatterjee, Kai-Min Chung, Xiao Liang, Giulio Malavolta · 2021

This work revisits the security of classical signatures and ring signatures in a quantum world. For (ordinary) signatures, we focus on the arguably preferable security notion of blind-unforgeability r…
