Holography for fermions

open access: yesJournal of High Energy Physics, 2004
The holographic interpretation is a useful tool to describe 5D field theories in a 4D language. In particular it allows one to relate 5D AdS theories with 4D CFTs. We elaborate on the 5D/4D dictionary for the case of fermions in AdS$_5$ with boundaries.

Heterodyne Holography with full control of both signal and reference arms

open access: yes, 2015
Heterodyne holography is a variant of phase shifting holography in which reference and signal arms are controlled by acousto optic modulators. In this review paper, we will briefy describe the method and its properties, and we will illustrate its ...

Compressive Holographic Video [PDF]

open access: yes, 2016
Compressed sensing has been discussed separately in spatial and temporal domains. Compressive holography has been introduced as a method that allows 3D tomographic reconstruction at different depths from a single 2D image.

Optoelectronic Devices for In‐Sensor Computing

open access: yesAdvanced Materials, EarlyView.
The raw data obtained directly from sensors in the noisy analogue domain is often unstructured, which lacks a predefined format or organization and does not conform to a specific data model. Optoelectronic devices for in‐sensor visual processing can integrate perception, memory, and processing functions in the same physical units, which can compress ...

Fabrication Method for Spin-Coating ITO-Competitive PEDOT:PSS onto PVDF Film

open access: yesInternational Journal of Polymer Science
This paper shows a four-order reduction of magnitude in sheet resistance for spin-coating poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) onto polyvinylidene fluoride (PVDF) film for a final sheet resistance comparable to commercially ...

Scalable Lithium Niobate Nanoimprinting for Nonlinear Metalenses

open access: yesAdvanced Materials, EarlyView.
A broadband polycrystalline lithium niobate platform is developed for highly versatile and scalable fabrication of nonlinear metasurfaces. This work demonstrates simultaneous second harmonic generation and wavefront‐shaping via a metalens on this platform.

Comments on Holographic Entanglement Entropy in TT Deformed CFTs

open access: yes, 2019
The Ryu-Takayanagi (RT) formula has been a key ingredient in our understanding of holography. Recent work on TT deformations has also boosted our understanding of holography away from the conformal boundary of AdS.

Holography and unitarity [PDF]

open access: yesJournal of High Energy Physics, 2020
Abstract If holography is an equivalence between quantum theories, one might expect it to be described by a map that is a bijective isometry between bulk and boundary Hilbert spaces, preserving the hamiltonian and symmetries.
