Composite Hybrid Inflation : Primordial Black Holes and Stochastic Gravitational Waves
Giacomo Cacciapaglia, Dhong Yeon Cheong, Aldo Deandrea +4
We investigate the production of primordial black holes and gravitational waves in composite hybrid inflation. Starting from an effective chiral Lagrangian with a dilaton and pions…
Explicit Quantum Circuits for Simulating Linear Differential Equations via Dilation
Seonggeun Park
Quantum simulation has primarily focused on unitary dynamics, while many physical and engineering systems can be modeled by linear ordinary differential equations whose generators…
Quasinormal frequencies in Reissner-Nordström de Sitter black holes: constraints from space-time and scalar field parameters
Anna Chrysostomou, Alan S. Cornell, Aldo Deandrea +1
We examine the quasinormal modes exhibited by a massive scalar test field carrying an electric charge, oscillating in the outer region of a Reissner-Nordström de Sitter black hole…
Neural Hamilton: Can A.I. Understand Hamiltonian Mechanics?
Tae-Geun Kim, Seong Chan Park
We propose a novel framework based on neural network that reformulates classical mechanics as an operator learning problem. A machine directly maps a potential function to its corr…
