Exploring robust correlations between fermionic dark matter model parameters and neutron star properties: A two-fluid perspective
Prashant Thakur, Tuhin Malik, Arpan Das +2
The current observational properties of neutron stars have not definitively ruled out the possibility of dark matter. In this study, we primarily focus on exploring correlations be…
Relativistic second-order spin hydrodynamics: an entropy-current analysis
Rajesh Biswas, Asaad Daher, Arpan Das +2
We present a new derivation of Israel-Stewart-like relativistic second-order dissipative spin hydrodynamic equations using the entropy current approach. In our analysis, we conside…
Boost invariant spin hydrodynamics within the first order in derivative expansion
Rajesh Biswas, Asaad Daher, Arpan Das +2
Boost-invariant equations of spin hydrodynamics confined to the first-order terms in gradients are numerically solved. The spin equation of state, relating the spin density tensor…
Stability studies of first order spin-hydrodynamic frameworks
Asaad Daher, Arpan Das, Radoslaw Ryblewski
We study the stability of first-order dissipative spin-hydrodynamic frameworks. We considered two different first-order dissipative spin-hydrodynamic frameworks. The first one cons…
Strongly coupled quantum Otto cycle with single qubit bath
Sagnik Chakraborty, Arpan Das, Dariusz Chruściński
We discuss a model of a closed quantum evolution of two-qubits where the joint Hamiltonian is so chosen that one of the qubits acts as a bath and thermalize the other qubit which i…
Precision bound and optimal control in periodically modulated continuous quantum thermal machines
Arpan Das, Shishira Mahunta, Bijay Kumar Agarwalla +1
We use Floquet formalism to study fluctuations in periodically modulated continuous quantum thermal machines. We present a generic theory for such machines, followed by specific ex…
