Entropic order parameters for the phases of QFT [PDF]

Journal of High Energy Physics, 2020
We propose entropic order parameters that capture the physics of generalized symmetries and phases in QFT’s. We do it through an analysis of simple properties (additivity and Haag duality) of the net of operator algebras attached to space-time regions ...

The pragmatic QFT measurement problem and the need for a Heisenberg-like cut in QFT [PDF]

Synthese, 2022
Despite quantum theory’s remarkable success at predicting the statistical results of experiments, many philosophers worry that it nonetheless lacks some crucial connection between theory and experiment.

Comparing the diagnostic performance of QuantiFERON-TB Gold Plus with QFT-GIT, T-SPOT.TB and TST: a systematic review and meta-analysis

BMC Infectious Diseases, 2023
Background QuantiFERON-TB Gold Plus (QFT-Plus) is an important test that has emerged in recent years for detecting TB infection. We conducted a review to compare the sensitivity, specificity and positive rate of QFT-Plus with that of QuantiFERON-TB Gold ...

Canonical Quantum Gravity, Constructive QFT, and Renormalisation [PDF]

Frontiers of Physics, 2020
The canonical approach to quantum gravity has been put on a firm mathematical foundation in the recent decades. Even the quantum dynamics can be rigorously defined, however, due to the tremendously non-polynomial character of the gravitational ...

Complexity of mixed states in QFT and holography [PDF]

Journal of High Energy Physics, 2019
We study the complexity of Gaussian mixed states in a free scalar field theory using the ‘purification complexity’. The latter is defined as the lowest value of the circuit complexity, optimized over all possible purifications of a given mixed state.

Comparing the Diagnostic Performance of QFT-Plus to Other Tests of Latent Tuberculosis Infection: A Systematic Review and Meta-analysis.

Clinical Infectious Diseases, 2020
BACKGROUND We conducted this review to compare the sensitivity, specificity, reproducibility, and predictive ability of QFT-Plus with that of QFT-GIT (QIAGEN, Hilden, Germany), T-SPOT.TB (Oxford Immunotec, Oxford, United Kingdom) and the tuberculin skin ...

Strongly coupled QFT dynamics via TQFT coupling [PDF]

, 2020
We consider a class of quantum field theories and quantum mechanics, which we couple to ZN topological QFTs, in order to classify non-perturbative effects in the original theory.

Comparing QuantiFERON-TB Gold Plus with QuantiFERON-TB Gold in-tube for diagnosis of latent tuberculosis infection among highly TB exposed gold miners in South Africa [version 3; peer review: 2 approved, 1 approved with reservations]

Gates Open Research, 2022
Background: QuantiFERON-TB-Gold-in-tube (QFT-GIT) is an interferon-gamma release assay (IGRA) used to diagnose latent tuberculosis infection. Limited data exists on performance of QuantiFERON-TB Gold-Plus (QFT-Plus), a next generation of IGRA that ...

Leading exponential finite size corrections for non-diagonal form factors

Journal of High Energy Physics, 2019
We derive the leading exponential finite volume corrections in two dimensional integrable models for non-diagonal form factors in diagonally scattering theories.

Comparison of QuantiFERON-TB Gold In-Tube and QuantiFERON-TB Gold-Plus in the Diagnosis of Mycobacterium tuberculosis Infections in Immunocompromised Patients: a Real-World Study

Microbiology Spectrum, 2022
QuantiFERON-TB Gold Plus (QFT-Plus) is an emerging QuantiFERON test after QuantiFERON-TB Gold In-Tube (QFT-GIT) for tuberculosis infection detection; it is an IFN-γ release assay.
