Statistical Fluctuations as Primordial Correlators in the CMB: Finite Chemical Potential Thermodynamics
Anish Ghoshal, Anupam Mazumdar, Bartłomiej Sikorski
Can primordial cosmological correlations originate from statistical fluctuations of an early-universe thermal system? We connect grand-canonical thermodynamics, stochastic transpor…
(De)Coherence of a quantum system in an anti-de Sitter spacetime
Mandas Biswas, Anupam Mazumdar
In this paper, we study the coherence/decoherence of a quantum harmonic oscillator in anti-de Sitter (AdS) spacetime by quantising the graviton in a curved background with a nontri…
The Weinberg no-go theorem for cosmological constant and nonlocal gravity
Salvatore Capozziello, Anupam Mazumdar, Giuseppe Meluccio
We show how a nonlocal gravitational interaction can circumvent the Weinberg no-go theorem on cosmological constant, which forbids the existence of any solution to the cosmological…
Spin-Dependent Force and Inverted Harmonic Potential for Rapid Creation of Macroscopic Quantum Superpositions
Run Zhou, Qian Xiang, Anupam Mazumdar
Creating macroscopic spatial superposition states is crucial for investigating matter-wave interferometry and advancing quantum sensor technology. Currently, two potential methods…
Can nonlocal gravity really explain dark energy?
Salvatore Capozziello, Anupam Mazumdar, Giuseppe Meluccio
In view to scrutinize the idea that nonlocal modifications of General Relativity could dynamically address the dark energy problem, we investigate the evolution of the Universe at…
Inertial Torsion Noise in Matter-Wave Interferometers for Gravity Experiments
Meng-Zhi Wu, Marko Toroš, Sougato Bose +1
Matter-wave interferometry is susceptible to non-inertial noise sources, which can induce dephasing and a resulting loss of interferometric visibility. Here, we focus on inertial t…
