Challenges in using GPUs for the real-time reconstruction of digital hologram images [PDF]
, 2013 This is the pre-print version of the final published paper that is available from the link below.In-line holography has recently made the transition from silver-halide based recording media, with laser reconstruction, to recording with large-area pixel ...

The Covariant Entropy Bound, Brane Cosmology, and the Null Energy Condition [PDF]
, 2002 In discussions of Bousso's Covariant Entropy Bound, the Null Energy Condition is always assumed, as a sufficient {\em but not necessary} condition which helps to ensure that the entropy on any lightsheet shall necessarily be finite.

Lensfree super-resolution holographic microscopy using wetting films on a chip. [PDF]
, 2011 We investigate the use of wetting films to significantly improve the imaging performance of lensfree pixel super-resolution on-chip microscopy, achieving < 1 µm spatial resolution over a large imaging area of ~24 mm(2).

Three-dimensional spatiotemporal focusing of holographic patterns
Nature Communications, 2016 Three-dimensional computer-generated holography cannot be implemented with temporal focusing. Here, Hernandez et al. use two spatial light modulators to control transverse- and axial-target light distribution, generating spatiotemporally focused patterns

Moment‐Based Shape‐Learning Holography for Fast Classification of Microparticles
Advanced Photonics Research, 2023 Compact computational in‐line holography based on deep learning is an attractive single‐shot approach to image microparticles dispersed in 3D volume. The particle shape contains valuable information for species classification, but the dataset acquisition

Crossing a large-N phase transition at finite volume
Journal of High Energy Physics, 2021 The existence of phase-separated states is an essential feature of infinite-volume systems with a thermal, first-order phase transition. At energies between those at which the phase transition takes place, equilibrium homogeneous states are either ...

Supersymmetric black holes with spiky horizons
Journal of High Energy Physics, 2021 We use the recipe of [1] to find half-BPS near-horizon geometries in the t3 model of N = 2, D = 4 gauged supergravity, and explicitely construct some new examples.
