Holographic Stripes

, 2013
We construct inhomogeneous asymptotically AdS black hole solutions corresponding to the spontaneous breaking of translational invariance and the formation of striped order in the boundary field theory.

Phototunable Polarization Volume Gratings Driven by Chiral Hydrazone Switches

Advanced Optical Materials, EarlyView.
Chiral hydrazone photoswitches incorporated into polarization volume gratings enable light‐driven, reversible modulation of optical properties. UV and blue light irradiation reversibly alter the hydrazone isomer ratio, leading to tunable diffraction efficiency and spectral response across the visible spectrum.

Universal scaling properties of extremal cohesive holographic phases [PDF]

, 2014
We show that strongly-coupled, translation-invariant holographic IR phases at finite density can be classified according to the scaling behaviour of the metric, the electric potential and the electric flux introducing four critical exponents ...

Harnessing Ultrafast Optical Pulses for 3D Microfabrication by Selective Tweezing and Immobilization of Colloidal Particles in an Integrated System

Advanced Photonics Research, Volume 6, Issue 5, May 2025.
Microfabrication using nano‐ to micron‐sized blocks has transformative potential for next‐gen electronics, optoelectronics, and materials. Traditional methods are limited by scalability and precision. STIC, a single‐laser system for precise colloid manipulation and immobilization using femtosecond lasers, is introduced that enables efficient 3D ...

Observing the origin of superconductivity in quantum critical metals [PDF]

, 2011
Despite intense efforts during the last 25 years, the physics of unconventional superconductors, including the cuprates with a very high transition temperature, is still a controversial subject.

Direct Photocurrent Detection of Optical Vortex Based on the Orbital Photo Galvanic Effect: Progress, Challenge, and Perspective

Advanced Science, EarlyView.
Direct orbital angular momentum (OAM) detection through the orbital photogalvanic effect offers a scalable route for integrated optoelectronics. This perspective evaluates symmetry‐driven material selection and demonstrates how electrode matrices enable the resolution of complex, mixed OAM modes.

Mixed‐Functionalized Acylgermanes Result in Wavelength‐Controlled Fragmentation

Angewandte Chemie, EarlyView.
Selective radical generation from PEG‐acylgermanes is achieved by controlling the used wavelength. Distinct aryl‐carbonyl units undergo wavelength‐dependent α‐cleavage, producing radicals with different reactivities. UV/Vis, TD‐DFT, and photo‐CIDNP spectroscopy confirm that small adjustments in light input directly dictate radical identity and ...

Digital Holographic Three-Dimensional Video Displays [PDF]

Proceedings of the IEEE, 2011
Holography aims to record and regenerate volume filling light fields to reproduce ghost-like 3-D images that are optically indistinguishable from their physical 3-D originals. Digital holographic video displays are pixelated devices on which digital holograms can be written at video rates.
