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…
Semi-classical kinetic theory for massive spin-half fermions with leading-order spin effects
Arpan Das, Wojciech Florkowski, Avdhesh Kumar +2
We consider the quantum kinetic-theory description for interacting massive spin-half fermions using the Wigner function formalism. We derive a general kinetic theory description as…
Canonical and phenomenological formulations of spin hydrodynamics
Asaad Daher, Arpan Das, Wojciech Florkowski +1
Two formulations of relativistic hydrodynamics of particles with spin 1/2 are compared. The first approach, dubbed the canonical one, uses expressions for the energy-momentum and s…
