Embedding Unimodular Gravity in string theory
Journal of High Energy Physics, 2023 Unimodular Gravity is a theory displaying Weyl rescalings of the metric and transverse (volume-preserving) diffeomorphisms as gauge symmetries, as opposed to the full set of diffeomorphisms displayed by General Relativity.

ECSS: High-Embedding-Capacity Audio Watermarking with Diversity Reception
Entropy, 2022 Digital audio watermarking is a promising technology for copyright protection, yet its low embedding capacity remains a challenge for widespread applications. In this paper, the spread-spectrum watermarking algorithm is viewed as a communication channel,

Quantum Embedding Theory for Strongly Correlated States in Materials
Journal of Chemical Theory and Computation, 2021 : Quantum embedding theories are promising approaches to investigate strongly correlated electronic states of active regions of large-scale molecular or condensed systems. Notable examples are spin defects in semiconductors and insulators.

Green’s Function Formulation of Quantum Defect Embedding Theory [PDF]
Journal of Chemical Theory and Computation, 2022 We present a Green's function formulation of the quantum defect embedding theory (QDET) where a double counting scheme is rigorously derived within the $G_0 W_0$ approximation.

Density Matrix Embedding: A Strong-Coupling Quantum Embedding Theory [PDF]
Journal of Chemical Theory and Computation, 2013 We extend our density matrix embedding theory (DMET) [Phys. Rev. Lett. 109 186404 (2012)] from lattice models to the full chemical Hamiltonian. DMET allows the many-body embedding of arbitrary fragments of a quantum system, even when such fragments are open systems and strongly coupled to their environment (e.g., by covalent bonds).

Quantum mechanical embedding theory based on a unique embedding potential
The Journal of Chemical Physics, 2011 We remove the nonuniqueness of the embedding potential that exists in most previous quantum mechanical embedding schemes by letting the environment and embedded region share a common embedding (interaction) potential.
