Present status and future challenges of non-interferometric tests of collapse models
The superposition principle is the cornerstone of quantum mechanics, leading to a variety of
genuinely quantum effects. Whether the principle applies also to macroscopic systems or …

Statistical mechanics of active Ornstein-Uhlenbeck particles
We study the statistical properties of active Ornstein-Uhlenbeck particles (AOUPs). In this
simplest of models, the Gaussian white noise of overdamped Brownian colloids is replaced …

Black holes: eliminating information or illuminating new physics?
S Chakraborty, K Lochan - Universe, 2017 - mdpi.com
Black holes, initially thought of as very interesting mathematical and geometric solutions of
general relativity, over time, have come up with surprises and challenges for modern …

Quantum corrected charged thin-shell wormholes surrounded by quintessence
In this manuscript, we inspect the stable geometry of thin-shell wormholes in the framework
of static, spherically-symmetric quantum corrected charged black hole solution bounded by …

Quantum discord of cosmic inflation: Can we show that CMB anisotropies are of quantum-mechanical origin?
J Martin, V Vennin - Physical Review D, 2016 - APS
We investigate the quantumness of primordial cosmological fluctuations and its detectability.
The quantum discord of inflationary perturbations is calculated for an arbitrary splitting of the …

Assessing the scientific status of inflation after Planck
D Chowdhury, J Martin, C Ringeval, V Vennin - Physical Review D, 2019 - APS
Inflation is considered as the best theory of the early universe by a very large fraction of
cosmologists. However, the validity of a scientific model is not decided by counting the …

Note on single-field inflation and the swampland criteria
S Das - Physical Review D, 2019 - APS
The recently proposed swampland criteria aim to evade any (meta-) stable de Sitter
constructions within string landscapes, making it difficult to accommodate accelerating …

Obstructions to Bell CMB experiments
J Martin, V Vennin - Physical Review D, 2017 - APS
We present a general and systematic study of how a Bell experiment on the cosmic
microwave background could be carried out. We introduce different classes of pseudo-spin …
