Nuclear interference versus dark sector excitation in the 248 keV LUX-ZEPLIN recoil candidate
Imtiaz Khan, Salvatore Capozziello, G. Mustafa +3
The 2026 LUX-ZEPLIN (LZ) high energy nuclear recoil search reports one event at and finds the elastic isovector interaction $\math…
Finite-duration non-slow-roll effects in inflationary production of ultralight vector dark matter
Imtiaz Khan, Niamat Ullah, Chengxun Yuan +3
Inflationary production of ultralight vector dark matter can be amplified by a brief non-slow-roll phase, yet instantaneous mass transitions generate ultraviolet ringing and leave…
Energy extraction processes and thermodynamics in rotating Weyl conformal black holes
Dilmurod Ortiqboev, Farruh Atamurotov, Ahmadjon Abdujabbarov +2
This work investigates the original Penrose process (PP), as well as black hole (BH) thermodynamics, within the framework of conformal Weyl gravity. The theory is characterized by…
Coherent and Stochastic Axion Dark Matter from Thermal Relaxation
Shahid Hussain Gurmani, Arzu Cilli, Phongpichit Channuie +3
An axion driven toward a thermal minimum need not remain a coherent condensate. We derive the coupled attenuation of the field mean and production of stochastic momentum modes in a…
Thermal Alignment as a Pathway to Axion Dark Matter
Imtiaz Khan, G. Mustafa, Chengxun Yuan +3
Thermal alignment cannot be inferred from the axion mean alone because the dissipative bath that erases the initial displacement also prepares field and momentum fluctuations. We d…
Dilaton-Induced Resonant Production of Ultralight Vector Dark Matter
Imtiaz Khan, G. Mustafa, Jehanzad Zafar +3
A dilatonic half-mass resonance can produce ultralight vector dark matter only if the Floquet instability becomes efficient before the oscillating spectator scalar dominates the co…
Chaotic motion and power spectral density in Schwarzschild Bertotti-Robinson black hole spacetime
Yunqiao Xu, Uktamjon Uktamov, Pierros Ntelis +3
In this paper, we show that in weak field limit Schwarzschild Bertotti-Robinson black hole (Schwarzschild-BR BH) turns into Schwarzschild black hole immersed in external uniform ma…
Plasma impact on black hole shadow and gravitational weak lensing for Schwarzschild-like black hole
Weiqiang Yang, Mirzabek Alloqulov, Ahmadjon Abdujabbarov +3
This article delves into the observational properties of a Schwarzschild-like black hole (BH). Initially, the research provides a succinct examination of the spacetime geometry and…
Effect of gravitational lensing around black hole in dark matter halo in the presence of plasma
Zhiyu Dou, Akbar Davlataliev, Mirzabek Alloqulov +4
This article is devoted to the investigation of the observational properties of the Schwarzschild black hole (BH) surrounded by a dark matter (DM) halo. Our study commences with a…
