Gauge Backreaction in Standard Model Warm Inflation
Rafid H. Dejrah, Anish Ghoshal
Standard-Model warm inflation (SMWI) makes QCD the microscopic origin of inflationary dissipation, so the real-time response of the gauge plasma enters the cosmological prediction.…
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…
Primordial Black Hole Assisted Dirac Leptogenesis
Marco Manno, Anish Ghoshal
Dirac leptogenesis offers a qualitatively different route to the baryon asymmetry: total lepton number is conserved, but equal and opposite asymmetries are stored in the Standard M…
Impact of Scale-dependent Primordial Non-Gaussianity on Scalar-induced Gravitational Waves
Alisha Marriott-Best, Devanshu Sharma, Anish Ghoshal +1
Scalar-induced gravitational waves (SIGWs) probe primordial curvature perturbations beyond cosmic microwave background scales, while primordial black holes (PBHs) probe the rare ta…
Exact Lattice Identities and Continuum-Limit Dyson--Schwinger Equations for Yang-Mills Theory
Arpan Chatterjee, Marco Frasca, Anish Ghoshal +1
Starting from SU(N) on the lattice, we give a rigorous derivation of the Dyson--Schwinger equations in the continuum limit. We formulate the Dyson--Schwinger identities for the lat…
Magnetically assisted primordial scalar perturbations: Scalar-Induced Gravitational Waves
Arko Bhaumik, Theodoros Papanikolaou, Anish Ghoshal
Primordial magnetic fields (PMFs) provide a well-motivated source of cosmological perturbations through their anisotropic stress and may leave observable imprints in both the scala…
