Hartree shift and pairing gap in ultracold Fermi gases in the framework of low-momentum interactions
Michael Urban, S. Ramanan
In this paper we consider a two-component gas of fermions on the BCS side of the BCS-BEC crossover at zero temperature. We use a momentum dependent interaction that reproduces the…
Estimation of deuteron binding energy with renormalization group-based effective interactions using the variational quantum eigensolver
Sreelekshmi Pillai, S. Ramanan, V. Balakrishnan +1
We have obtained the energy of the deuteron on a quantum simulator using the variational quantum eigensolver. We have employed realistic two-body interactions, namely, chiral N4LO…
Induced three-neutron interactions with low cutoffs for dilute neutron matter
Viswanathan Palaniappan, S. Ramanan, Michael Urban
The properties of dilute neutron matter are mostly determined by the s-wave two-body (2N) interaction, while three-body (3N) interactions are suppressed by the Pauli principle. In…
A tomographic approach to the sum uncertainty relation and quantum entanglement in continuous variable systems
Soumyabrata Paul, S. Lakshmibala, V. Balakrishnan +1
Entropic uncertainty relations (EURs) have been examined in various contexts, primarily in qubit systems, including their links with entanglement, as they subsume the Heisenberg un…
Equation of state of superfluid neutron matter with low-momentum interactions
Viswanathan Palaniappan, S. Ramanan, Michael Urban
In this work, we calculate the ground state energy of pure neutron matter using the renormalization group based low-momentum effective interaction in Bogoliubov…
Manifestations of changes in entanglement and onset of synchronization in tomograms
Soumyabrata Paul, S. Lakshmibala, V. Balakrishnan +1
Quantum state reconstruction for continuous-variable systems such as the radiation field poses challenges which arise primarily from the large dimensionality of the Hilbert space.…
