Breakdown of emergent Lifshitz symmetry in holographic matter with Harris-marginal disorder
Journal of High Energy Physics, 2020 We revisit the theory of strongly correlated quantum matter perturbed by Harris-marginal random-field disorder, using the simplest holographic model. We argue that for weak disorder, the ground state of the theory is not Lifshitz invariant with a non ...

Model Independent Primordial Power Spectrum from Maxima, Boomerang, and DASI Data
, 2002 A model-independent determination of the primordial power spectrum of matter density fluctuations could uniquely probe physics of the very early universe, and provide powerful constraints on inflationary models.

Low-energy effects of Lepton Flavour Universality Violation
Journal of High Energy Physics, 2018 The persisting anomalous data in semileptonic B-decays point towards New Physics models exhibiting large sources of Lepton Flavour Universality Violation. In this work we generalise previous studies by considering frameworks which include an enlarged set

The Poisson structure of the mean-field equations in the Phi^4 theory
, 1998 We show that the mean-field time dependent equations in the Phi^4 theory can be put into a classical non-canonical hamiltonian framework with a Poisson structure which is a generalization of the standard Poisson bracket.

AAPM medical physics practice guideline 13.a: HDR brachytherapy, part B
Journal of Applied Clinical Medical Physics, EarlyView.Abstract The goal of this report is to assist the clinical medical physicist in assuring that key quality standards and practice considerations are met to ensure safe, reliable, and reproducible high dose rate (HDR) brachytherapy (BT) treatment. This guideline has been developed to provide appropriate minimum standards for such services.

Scale-invariant dynamical fluctuations in jet physics [PDF]
The European Physical Journal C, 1999 An interpretation of scale-invariant multiplicity fluctuations inside hadronic jets is presented. It is based on the branching mechanism with the angular ordering of soft partons in sequential branchings. A relationship with fractal distributions is demonstrated.

Automated rapidplan model validation using Eclipse scripting API
Journal of Applied Clinical Medical Physics, EarlyView.Abstract RapidPlan offers efficiency gains and quality improvements in treatment planning. Prior to its use in the clinic, it requires an extensive validation procedure in which established clinical plans and those generated by the model are compared. The manual iterative nature of this process is resource intensive, as numerous iterations are required

Experimental Non-Violation of the Bell Inequality
Entropy, 2018 A finite non-classical framework for qubit physics is described that challenges the conclusion that the Bell Inequality has been shown to have been violated experimentally, even approximately.
