Light–matter quantum dynamics of complex laser-driven systems [PDF]

The Journal of Chemical Physics, 2021
We propose a novel general approximation to transform and simplify the description of a complex fully quantized system describing the interacting light and matter. The method has some similarities to the time-dependent Born–Oppenheimer approach: we consider a quantum description of light rather than of nuclei and follow a similar separation procedure ...

Light sailboats: Laser driven autonomous microrobots [PDF]

Applied Physics Letters, 2012
We introduce a system of light driven microscopic autonomous moving particles that move on a flat surface. The design is simple, yet effective: Micrometer sized objects with wedge shape are produced by photopolymerization, they are covered with a reflective surface.

Laser-Driven Light Sources for Nanometrology Applications

Journal of Microelectronic Manufacturing, 2019
Laser-driven light sources (LDLS) have ultrahigh-brightness and broad wavelength range. They are ideal radiation sources for optical metrology tools for advanced process control in semiconductor manufacturing. LDLS sources, with their advantages of 170 nm to 2100 nm wavelength range, have been widely adopted and are being used in volume manufacturing ...

High-sensitivity electronic Stark spectrometer featuring a laser-driven light source

Review of Scientific Instruments, 2023
We report developmental details of a high-sensitivity Stark absorption spectrometer featuring a laser-driven light source. The light source exhibits intensity fluctuations of ∼0.3% over timescales ranging from 1 min to 12 h, minimal drift (≤0.1%/h), and very little 1/f noise at frequencies greater than 200 Hz, which are comparable to or better than an ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Lowering operating temperatures in high-power laser-excited LuAG:Ce films by improving crystallinity and increasing Ce3+ content

Journal of Advanced Ceramics
High operating temperatures generally degrade the luminous performance of color converters used in high-power, laser-driven white lighting systems. This study demonstrated that the operating temperature of LuAG:Ce films can be significantly reduced ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Broadband white light emission from Ce:AlN ceramics: High thermal conductivity down-converters for LED and laser-driven solid state lighting

APL Materials, 2016
We introduce high thermal conductivity aluminum nitride (AlN) as a transparent ceramic host for Ce3+, a well-known active ion dopant. We show that the Ce:AlN ceramics have overlapping photoluminescent (PL) emission peaks that cover almost the entire ...

Investigating transcription factor dynamics in health and disease using FRAP

FEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...
