Quasinormal-mode analysis of a massive scalar field in a Schwarzschild background via the spectral method
Davide Batic, Anna Chrysostomou, Alan S. Cornell +1
We study the massive scalar quasinormal-mode spectral problem on a Schwarzschild background using an extended Chebyshev spectral method. The massive dispersion relation has a two-s…
Quasinormal modes of Hayward black holes from Schwarzschild to extremality: a comparative spectral analysis
Davide Batic, Denys Dutykh
We study scalar and electromagnetic quasinormal modes of the Hayward black hole and the axial spectrum of a specified Regge--Wheeler-type effective model, from the Schwarzschild li…
An exact Kerr-like rotating Morris--Thorne wormhole: throat, ergoregion and equatorial shadow slice
Mark Sukaiti, Davide Batic, Denys Dutykh
We construct an exact Kerr-like rotating extension of the zero-redshift Morris--Thorne wormhole in a Teo-type stationary, axisymmetric ansatz. The Einstein equations for an anisotr…
Performance Analysis of Cooperative Multi-Carrier Relay-Based UAV Networks Over Generalized Fading Channels
Ibrahim Y. Abualhaol, Mustafa M. Matalgah
The outage probability in a network of cooperative unmanned airborne vehicles (UAVs) over generalized fading channels is studied analytically using finite mixture with expectation…
Position- and Momentum-Space Quantum Information Measures of the Double-Morse Oscillator
Firoz Chogle, Ernesto Damiani, Berihu Teklu
We investigate the quantum-information properties of a particle confined by the double Morse potential in position and momentum spaces. The quasi-exact solvability of the model giv…
Self-Supervised Graph Representation Learning for In-The-Wild Wearable and Smartphone based Emotion Recognition
Ioannis N. Ziogas, Leontios J. Hadjileontiadis, Ahsan H. Khandoker +1
Wearable and smartphone-based emotion recognition (WER) remains a challenging setting in affective computing, due to the notorious difficulty and bias associated with in-the-wild l…
