Using physics-informed neural networks to compute quasinormal modes
Alan S. Cornell, Anele Ncube, Gerhard Harmsen
In recent years there has been an increased interest in neural networks, particularly with regard to their ability to approximate partial differential equations. In this regard, re…
Boosted decision trees in the era of new physics: a smuon analysis case study
Alan S. Cornell, Wesley Doorsamy, Benjamin Fuks +2
Machine learning algorithms are growing increasingly popular in particle physics analyses, where they are used for their ability to solve difficult classification and regression pr…
Investigating a New Approach to Quasinormal Modes: Physics-Informed Neural Networks
Anele M Ncube, Gerhard E Harmsen, Alan S Cornell
Physics-informed neural networks (PINNs) hold the potential for supplementing the existing set of techniques for solving differential equations that emerge in the study of black ho…
Master equations and Quasi-normal modes of spin-3/2 fields in Schwarzschild (A)dS black hole spacetimes
Chun-Hung Chen, Hing-Tong Cho, Alan S. Cornell +1
In this work we consider spin-3/2 fields in Schwarzschild (A)dS black hole spacetimes. As this spacetime is different from the Ricci-flat cases, it is necessary to modify the covar…
Towards nonsingular rotating compact object in ghost-free infinite derivative gravity
Luca Buoninfante, Alan S. Cornell, Gerhard Harmsen +4
The vacuum solution of Einstein's theory of general relativity provides a rotating metric with a ring singularity, which is covered by the inner and outer horizons, and an ergo reg…
Quasi-normal modes of spin-3/2 fields in -dimensional Reissner-Nordström black hole spacetimes using the continued fraction method
Alan S. Cornell, Gerhard E. Harmsen
In a recent paper we calculated the field equations of spin-3/2 fields in a -dimensional Reissner-Nordström black hole spacetime whilst maintaining the gauge symmetry of the Rar…
Non-singular metric for an electrically charged point-source in ghost-free infinite derivative gravity
Luca Buoninfante, Gerhard Harmsen, Shubham Maheshwari +1
In this paper we will construct a linearized metric solution for an electrically charged system in a {\it ghost-free} infinite derivative theory of gravity which is valid in the en…
Quasi-normal modes and absorption probabilities of spin-3/2 fields in -dimensional Reissner-Nordström black hole spacetimes
C. -H. Chen, H. T. Cho, A. S. Cornell +2
In this paper we consider spin-3/2 fields in a -dimensional Reissner-Nordström black hole spacetime. As these spacetimes are not Ricci-flat, it is necessary to modify the covari…
Rotating metric in Non-Singular Infinite Derivative Theories of Gravity
Alan S. Cornell, Gerhard Harmsen, Gaetano Lambiase +1
In this paper we will provide a non-singular rotating space time metric for a ghost free infinite derivative theory of gravity. We will provide the predictions for the Lense-Thirri…
Absorption probabilities associated with spin-3/2 particles near -dimensional Schwarzschild black holes
G. E. Harmsen, C. H. Chen, H. T. Cho +1
In June 2015 the Large Hadron Collider was able to produce collisions with an energy of 13TeV, where collisions at these energy levels may allow for the formation of higher dimensi…
Gravitino fields in Schwarzschild black hole spacetimes
C. -H. Chen, H. T. Cho, A. S. Cornell +2
The analysis of gravitino fields in curved spacetimes is usually carried out using the Newman-Penrose formalism. In this paper we consider a more direct approach with eigenspinor-v…
