Implications of triangular features in the Gaia skymap for the Caustic Ring Model of the Milky Way halo
Sankha S. Chakrabarty, Yaqi Han, Anthony H. Gonzalez +1
The Gaia map of the Milky Way reveals a pair of triangular features at nearly symmetric locations on opposite sides of the Galactic Center. In this paper we explore the implication…
Duration of Classicality of an inhomogeneous quantum field with repulsive contact self-interactions
Ariel Arza, Sankha S. Chakrabarty, Seishi Enomoto +2
Quantum fields with large degeneracy are often approximated as classical fields. Here, we show how quantum and classical evolution of a highly degenerate quantum field with repulsi…
Duration of Classicality of Homogeneous Condensates with Attractive Interactions
Sankha Chakrabarty, Seishi Enomoto, Yaqi Han +2
Dark matter axions and other highly degenerate bosonic fluids are commonly described by classical field equations. In a recent paper \cite{BECprop} we calculated the duration of cl…
Gravitational self-interactions of a degenerate quantum scalar field
Sankha S. Chakrabarty, Seishi Enomoto, Yaqi Han +2
We develop a formalism to help calculate in quantum field theory the departures from the description of a system by classical field equations. We apply the formalism to a homogeneo…
Duration of classicality in highly degenerate interacting Bosonic systems
Pierre Sikivie, Elisa M. Todarello
We study sets of oscillators that have high quantum occupancy and that interact by exchanging quanta. It is shown by analytical arguments and numerical simulation that such systems…
