Local Quantum Cooling for Large Fermi Systems with Pairing

J. E. Alba-Arroyo, Daniel Pęcak, Michael McNeil Forbes +1

We present a framework for local quantum cooling that can be efficiently applied to large-scale Fermi systems. The method introduces local Hermitian operators as a cooling potentia…

A Minimal Nuclear Energy Density Functional

Aurel Bulgac, Michael McNeil Forbes, Shi Jin +2

We present a minimal nuclear energy density functional (NEDF) called "SeaLL1" that has the smallest number of possible phenomenological parameters to date. SeaLL1 is defined by 7 s…

Microscopic Calculations of Vortex-Nucleus Interaction in the Neutron Star Crust

Kazuyuki Sekizawa, Gabriel Wlazłowski, Piotr Magierski +2

We investigate the dynamics of a quantized vortex and a nuclear impurity immersed in a neutron superfluid within a fully microscopic time-dependent three-dimensional approach. The…

Nuclear Energy Density Functionals: What do we really know?

Aurel Bulgac, Michael McNeil Forbes, Shi Jin

We present the simplest nuclear energy density functional (NEDF) to date, determined by only 4 significant phenomenological parameters, yet capable of fitting measured nuclear mass…

The neutron polaron as a constraint on nuclear density functionals

M. M. Forbes, A. Gezerlis, K. Hebeler +2

We study the energy of an impurity (polaron) that interacts strongly in a sea of fermions when the effective range of the impurity-fermion interaction becomes important, thereby ma…

Quantum Friction: Cooling Quantum Systems with Unitary Time Evolution

Aurel Bulgac, Michael McNeil Forbes, Kenneth J. Roche +1

We introduce a type of quantum dissipation -- local quantum friction -- by adding to the Hamiltonian a local potential that breaks time-reversal invariance so as to cool the system…

Strength of the Vortex-Pinning Interaction from Real-Time Dynamics

Aurel Bulgac, Michael McNeil Forbes, Rishi Sharma

We present an efficient and general method to compute vortex-pinning interactions - which arise in neutron stars, superconductors, and trapped cold atoms - at arbitrary separations…

Use of the Discrete Variable Representation Basis in Nuclear Physics

Aurel Bulgac, Michael McNeil Forbes

The discrete variable representation (DVR) basis is nearly optimal for numerically representing wave functions in nuclear physics: Suitable problems enjoy exponential convergence,…

Broyden's Method in Nuclear Structure Calculations

Andrzej Baran, Aurel Bulgac, Michael McNeil Forbes +4

Broyden's method, widely used in quantum chemistry electronic-structure calculations for the numerical solution of nonlinear equations in many variables, is applied in the context…
