Dynamically and thermodynamically stable black holes in Einstein-Maxwell-dilaton gravity

Journal of High Energy Physics, 2020
We consider Einstein-Maxwell-dilaton gravity with the non-minimal exponential coupling between the dilaton and the Maxwell field emerging from low energy heterotic string theory.

Harnessing Machine Learning to Understand and Design Disordered Solids

Advanced Intelligent Discovery, EarlyView.
This review maps the dynamic evolution of machine learning in disordered solids, from structural representations to generative modeling. It explores how deep learning and model explainability transform property prediction into profound physical insight.

Supersymmetric Gödel and warped black holes in string theory [PDF]

, 2008
It is observed that three-dimensional Goedel black holes can be promoted to exact string theory backgrounds through an orbifold of a hyperbolic asymmetric marginal deformation of the SL(2,R) Wess-Zumino-Witten model. Tachyons are found in the spectrum of

Microscopic Calabi-Yau Black Holes in String Theory [PDF]

, 2011
In this thesis we study microscopic aspects of Calabi-Yau black holes in string theory. We compute the absorption cross-section of the space-time massless scalars by the world-volume of D2-branes, wrapped on the S2 of an AdS_2 x S^2 x CY_3 geometry of a ...

From black strings to fundamental strings: non-uniformity and phase transitions

Journal of High Energy Physics
We discuss the transition between black strings and fundamental strings in the presence of a compact dimension, S z 1 $$ {\mathbbm{S}}_z^1 $$ . In particular, we study the Horowitz-Polchinski effective field theory in ℝ d × S z 1 $$ {\mathbb{R}}^d\times {

Notes on islands in asymptotically flat 2d dilaton black holes

Journal of High Energy Physics, 2020
We study the islands and the Page curve in the 1+1-dimensional eternal dilaton black hole models. Without islands, the entanglement entropy of the radiation grows linearly at late time.

Key Challenges for Commercializing Perovskite–Silicon Tandem Solar Cells

Carbon Energy, EarlyView.
This review discusses the scientific and technological challenges in advancing perovskite–silicon tandem solar cells (PSTSCs) from lab‐scale to commercial viability, focusing on long‐term stability, scalability, and economic feasibility. Key issues include intrinsic and extrinsic degradation factors, installation conditions, environmental impacts, and ...

Entropy function for non-extremal black holes in string theory [PDF]

, 2007
We generalize the entropy function formalism to five-dimensional and four-dimensional non-extremal black holes in string theory. In the near horizon limit, these black holes have BTZ metric as part of the spacetime geometry.

Ultra-spinning Chow’s black holes in six-dimensional gauged supergravity and their properties

Journal of High Energy Physics, 2021
By taking the ultra-spinning limit as a simple solution-generating trick, a novel class of ultra-spinning charged black hole solutions has been constructed from Chow’s rotating charged black hole with two equal-charge parameters in six-dimensional N ...
