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…
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…
Pairing in pure neutron matter
S. Ramanan, M. Urban
We review the long standing problem of superfluid pairing in pure neutron matter. For the -wave pairing, we summarize the state of the art of many-body approaches including diff…
Neutron pairing with medium polarization beyond the Landau approximation
M. Urban, S. Ramanan
We revisit the long-standing problem of the superfluid transition temperature in dilute neutron matter. It is well known that is strongly affected by medium polarizatio…
Screening and anti-screening of the pairing interaction in low-density neutron matter
S. Ramanan, M. Urban
We study pairing in low-density neutron matter including the screening interaction due to the exchange of particle-hole and RPA excitations. As bare force we employ the effective l…
