Holographic RG flows and Janus solutions from matter-coupled $$N=4$$ N = 4 gauged supergravity

European Physical Journal C: Particles and Fields, 2021
We study an $$SO(2)\times SO(2)\times SO(2)\times SO(2)$$ S O ( 2 ) × S O ( 2 ) × S O ( 2 ) × S O ( 2 ) truncation of four-dimensional $$N=4$$ N = 4 gauged supergravity coupled to six vector multiplets with $$SO(4)\times SO(4)$$ S O ( 4 ) × S O ( 4 ...

Patterning the Void: Combining L‐Systems with Archimedean Tessellations as a Perspective for Tissue Engineering Scaffolds

Advanced Functional Materials, EarlyView.
This study introduces a novel multi‐scale scaffold design using L‐fractals arranged in Archimedean tessellations for tissue regeneration. Despite similar porosity, tiles display vastly different tensile responses (1–100 MPa) and deformation modes. In vitro experiments with hMSCs show geometry‐dependent growth and activity. Over 55 000 tile combinations

New supersymmetric $$AdS_5$$ A d S 5 black strings from 5D $$N=4$$ N = 4 gauged supergravity

European Physical Journal C: Particles and Fields, 2023
We find a large class of new supersymmetric $$AdS_5$$ A d S 5 black strings from five-dimensional $$N=4$$ N = 4 gauged supergravity coupled to five vector multiplets with $$SO(2)_D\times SO(3)\times SO(3)$$ S O ( 2 ) D × S O ( 3 ) × S O ( 3 ) gauge group.

On‐Surface Indigo‐Based Bimolecular Coordination Networks with Programmable Regular or Vitreous Structure

Advanced Functional Materials, EarlyView.
A previously unreported coordination motif stabilising single Fe atoms by indigo chelation and pyridyl coordination on Au(111) has been revealed. By using planar tritopic pyridyl linkers (TPyB), extended 2D porous networks of indigo3(TPyB)2Fe6 form. These networks can be crystalline or vitreous and offer an environment where individual coordination ...

Modular forms and SL(2, ℤ)-covariance of type IIB superstring theory

Journal of High Energy Physics, 2019
The local higher-derivative interactions that enter into the low-energy expansion of the effective action of type IIB superstring theory with constant complex modulus generally violate the U(1) R-symmetry of IIB supergravity by q U units.

$$AdS_5$$ A d S 5 vacua and holographic RG flows from 5D $$N=4$$ N = 4 gauged supergravity

European Physical Journal C: Particles and Fields, 2023
We study five-dimensional $$N=4$$ N = 4 gauged supergravity coupled to five vector multiplets with $$SO(2)_D\times SO(3)\times SO(3)$$ S O ( 2 ) D × S O ( 3 ) × S O ( 3 ) gauge group.

Multiband Switchable Microwave Absorbing Metamaterials Based on Reconfigurable Kirigami–Origami

Advanced Functional Materials, EarlyView.
A reconfigurable metamaterial featuring tunable microwave‐absorbing and load‐bearing performance is proposed. Stretchable kirigami and bistable origami configurations are integrated as actuating components, and the synergistic deformation mechanisms are systematically analyzed.

Supercharging superstrata

Journal of High Energy Physics, 2019
We construct a new class of smooth horizonless microstate geometries of the supersymmetric D1-D5-P black hole in type IIB supergravity. We first work in the AdS3 × S 3 decoupling limit and use the fermionic symmetries of the theory to generate new ...

String theory or field theory? [PDF]

Physics-Uspekhi, 2002
The status of string theory is reviewed, and major recent developments - especially those in going beyond perturbation theory in the string theory and quantum field theory frameworks - are discussed. This analysis helps better understand the role and place of string theory in the modern picture of the physical world.

4D Mapping of ZIF Biocomposites for High Protein Loading and Tunable Release Profiles

Advanced Functional Materials, EarlyView.
Systematic four‐dimensional mapping of zeolitic imidazolate framework biocomposites reveals how precursor ratios, total concentration, and washing define crystalline phase, protein loading, and release kinetics. This comprehensive study identifies conditions yielding record loading (∼85%) and precise phase–property correlations.
