Abstract: We study stationary clouds of a gauged, complex scalar field on a magnetically (and possibly electrically as well) charged Kerr-Newman black hole (BH). The existence of a magnetic charge $Q_m$ promotes a north-south $textit{asymmetry}$ of the scalar clouds. This breakdown of the clouds’ $mathbb{Z}_2$-symmetry carries through to the spacetime $textit{geometry}$ for the non-linear continuation of the clouds: a family of magnetically charged (or dyonic) BHs with synchronized gauged scalar hair, which we construct. Their distinct phenomenology is illustrated by their imaging, exhibiting skewed shadows and lensing. Such hairy BHs could, in principle, result from the superradiant instability of magnetically charged Kerr-Newman BHs, unveiling a dynamical mechanism for creating north-south asymmetric BHs from standard $mathbb{Z}_2$-symmetric electrovacuum BHs.
Studying the Existence of Stationary Clouds on Charged Kerr-Newman Black Holes
In this study, we examine the properties of stationary clouds of a gauged, complex scalar field on a magnetically charged Kerr-Newman black hole (BH). The presence of a magnetic charge leads to an asymmetry in the scalar clouds, breaking their inherent $mathbb{Z}_2$-symmetry.
Implications on Spacetime Geometry
This asymmetry in the clouds has a direct influence on the spacetime geometry when the clouds are extended non-linearly. We observe the creation of a family of magnetically charged (or dyonic) BHs with synchronized gauged scalar hair. These new BHs exhibit distinct phenomenology compared to the standard electrovacuum BHs.
Phenomenology of Hairy Black Holes
The distinct features of these hairy BHs are visually manifested in their imaging. They display skewed shadows and lensing effects that differ from those of the standard BHs. This indicates that the introduction of synchronized gauged scalar hair on magnetically charged BHs can alter the observable properties of these celestial objects.
Potential Origin of Asymmetric Black Holes
This study suggests that these hairy BHs could potentially result from the superradiant instability of magnetically charged Kerr-Newman BHs. This proposes a dynamical mechanism through which standard $mathbb{Z}_2$-symmetric electrovacuum BHs can evolve into north-south asymmetric BHs.
Roadmap for Future Research
Investigation of the stability and long-term evolution of the magnetically charged BHs with synchronized gauged scalar hair.
Exploration of the possible observational signatures of these hairy BHs in astrophysical settings.
Further theoretical analysis to understand the underlying mechanisms causing the asymmetry in the scalar clouds and its impact on the spacetime geometry.
Investigation of other types of charges (such as electrical) and their effects on the scalar clouds and resulting BHs.
Experimental simulation or observation of these hairy BHs to confirm their existence and validate the theoretical predictions.
Challenges and Opportunities
While this study opens up exciting avenues for research, several challenges and opportunities lie ahead:
Challenges:
The stability and long-term behavior of these magnetically charged BHs with gauged scalar hair need to be thoroughly examined.
Identifying observational signatures of these hairy BHs in real astrophysical systems may be challenging due to their unique phenomenology.
Opportunities:
Understanding the mechanism behind the north-south asymmetry in the scalar clouds could provide profound insights into the nature of BHs and their formation.
Experimental detection or simulation of these hairy BHs would provide concrete evidence for the existence of such objects and validate theoretical predictions.
This study uncovers the potential for the existence of north-south asymmetric black holes, resulting from the introduction of synchronized gauged scalar hair on magnetically charged Kerr-Newman black holes. Further research is required to explore the stability, observational signatures, and underlying mechanisms of these hairy black holes.
With the advancements in quantum computing, researchers have been focusing on using quantum algorithms to solve combinatorial optimization problems. One of the key models used in this area is the Quadratic Unconstrained Binary Optimization (QUBO) model, which acts as a connection between quantum computers and combinatorial optimization problems. However, there has been a lack of research on QUBO modeling for variant problems related to the Dominating Problem (DP).
The Dominating Problem, also known as the Domination Problem, has applications in various real-world scenarios such as the fire station problem and social network theory. It has several variants, including independent DP, total DP, and k-domination. Despite its importance, there has been a scarcity of quantum computing research on these variant problems.
In this paper, the researchers aim to fill this research gap by investigating QUBO modeling methods for the classic DP and its variants. They propose a QUBO modeling method for the classic DP that can utilize fewer qubits compared to previous studies. This is a significant development as it lowers the barrier for solving DP on quantum computers, making it more accessible and feasible.
Furthermore, the researchers provide QUBO modeling methods for the first time for many variants of DP problems. This expansion of QUBO modeling techniques will contribute to the acceleration of DP’s entry into the quantum era. By providing methods for solving these variant problems on quantum computers, researchers can explore new possibilities and applications in combinatorial optimization.
Overall, this paper contributes to the field of quantum computing by addressing the lack of research on QUBO modeling for variant problems related to the Dominating Problem. The proposed QUBO modeling methods not only optimize the use of qubits for solving the classic DP but also provide new avenues for solving variant problems on quantum computers. This research opens up opportunities for further exploration and advancement in the field of combinatorial optimization on quantum platforms.

In his debut solo exhibition “Dinner Party (While the World Burns)”, artist Nicholas Bono Kennedy explores the delicate balance between beauty and burden in the face of pressing political and ecological challenges. Through his vibrant and colorful paintings, Kennedy invites viewers to reflect on how to find joy and appreciation in life despite the chaos and uncertainty that surrounds us.
One of the key themes in Kennedy’s work is the idea of cherishing objects and how they can cross the line into burdensome excess. In a world where consumerism and materialism are prevalent, many of us find ourselves surrounded by possessions that we no longer need or appreciate. Kennedy’s compositions often feature scenes of domestic life, with piles of pets and potted plants, representing the accumulation of personal belongings. These images prompt viewers to question their own attachment to material possessions and consider when objects become a burden rather than a source of enjoyment.
Another significant theme in Kennedy’s paintings is the issue of environmental degradation and the world burning around us. With climate change, deforestation, and other ecological challenges becoming more apparent, it is easy to feel overwhelmed and helpless. However, Kennedy’s work reminds us that amidst the chaos, there is still beauty to be found. His vibrant and lively compositions serve as a reminder to appreciate the natural world and find solace in its beauty, even as we grapple with its destruction.
Looking ahead, Kennedy’s exploration of the relationship between beauty and burden offers insights into potential future trends. As environmental awareness continues to grow, there is likely to be a greater emphasis on sustainable living and minimalism. People may start to prioritize experiences over material possessions, seeking joy and fulfillment in moments rather than things. This shift in mindset could have significant implications for industries such as fashion, home decor, and consumer goods.
In terms of art and creativity, Kennedy’s work suggests a movement towards more introspective and thought-provoking pieces. As society becomes more aware of the challenges we face, artists may turn to their craft as a means of expressing their concerns and exploring solutions. Art can serve as a powerful tool for raising awareness and inspiring change, and we may see a rise in socially and environmentally conscious artwork in the future.
Based on Kennedy’s exploration of finding beauty amid chaos, my prediction for the industry is that there will be a greater demand for art that offers a sense of hope and optimism. Artwork that can provide comfort and inspiration in troubled times will resonate with audiences. Artists who can capture the beauty of the natural world and convey a sense of urgency regarding environmental issues may find success in the future.
In terms of recommendations for the industry, I suggest that galleries and art institutions actively seek out and promote artists who tackle pressing social and ecological challenges in their work. By providing a platform for these artists, galleries can contribute to a broader conversation about the issues that our world faces and foster greater awareness and empathy among their audiences. Additionally, incorporating sustainability practices into the art industry, such as using eco-friendly materials and supporting artists who prioritize environmental stewardship, can help reduce the ecological burden of the art world.
In conclusion, Nicholas Bono Kennedy’s debut exhibition “Dinner Party (While the World Burns)” prompts viewers to reflect on the relationship between beauty and burden in the face of pressing political and ecological challenges. His vibrant and thought-provoking paintings offer insights into potential future trends, including a shift towards sustainable living, a demand for art that offers hope, and a greater emphasis on socially and environmentally conscious artwork. By actively promoting artists who tackle these pressing issues and incorporating sustainability practices, the art industry can play a significant role in raising awareness and inspiring change in the world.
