Multi-photon stimulated grasers assisted by laser-plasma interactions
C. -J. Yang, K. M. Spohr, D. Doria
We investigate theoretically the possibility of achieving the stimulated amplification of -rays. Herein, our approach circumvents the so-called ``graser dilemma" through a non-l…
A new scheme for isomer pumping and depletion with high-power lasers
C. -J. Yang, K. M. Spohr, M. Cernaianu +3
We propose a novel scheme for the population and depletion of nuclear isomers. The scheme combines the -photons with energies keV emitted during the interaction of…
Feasibility of perturbative generation of bound-states from resonances or virtual states
C. -J. Yang
I investigate whether it is possible to generate bound-states from resonances or virtual states through first-order perturbation theory. Using contact-type potentials as those appe…
Calculations for nuclear matter and finite nuclei within and beyond energy--density--functional theories through interactions guided by effective field theory
C. J. Yang, W. G. Jiang, S. Burrello +1
We propose a novel idea to construct an effective interaction under energy-density-functional (EDF) theories which is adaptive to the enlargement of the model space. Guided by effe…
The importance of few-nucleon forces in chiral effective field theory
C. -J. Yang, A. Ekström, C. Forssén +3
We study the importance of few-nucleon forces in chiral effective field theory for describing many-nucleon systems. A combinatorial argument suggests that three-nucleon forces -- w…
A Lee-Yang--inspired functional with a density--dependent neutron-neutron scattering length
M. Grasso, D. Lacroix, C. J. Yang
Inspired by the low--density Lee-Yang expansion for the energy of a dilute Fermi gas of density and momentum , we introduce here a Skyrme--type functional that contains on…
From bare interactions, low--energy constants and unitary gas to nuclear density functionals without free parameters: application to neutron matter
Denis Lacroix, Antoine Boulet, Marcella Grasso +1
We further progress along the line of Ref. [Phys. Rev. {\bf A 94}, 043614 (2016)] where a functional for Fermi systems with anomalously large -wave scattering length was p…
Power Counting in Peripheral Partial Waves: The Singlet Channels
M. Pavón Valderrama, M. Sánchez Sánchez, C. -J. Yang +3
We analyze the power counting of the peripheral singlet partial waves in nucleon-nucleon scattering. In agreement with conventional wisdom, we find that pion exchanges are perturba…
Chiral potential renormalized in harmonic-oscillator space
C. -J. Yang
We renormalize the chiral effective field theory (EFT) potential in harmonic-oscillator (HO) model space. The low energy constants (LECs) are utilized to absorb not just the ultra-…
From dilute matter to the equilibrium point in the energy--density--functional theory
C. J. Yang, M. Grasso, D. Lacroix
Due to the large value of the scattering length in nuclear systems, standard density--functional theories based on effective interactions usually fail to reproduce the nuclear Ferm…
Second--order equation of state with the Skyrme interaction. Cutoff and dimensional regularization with the inclusion of rearrangement terms
C. J. Yang, M. Grasso, X. Roca-Maza +2
We evaluate the second--order (beyond--mean--field) contribution to the equation of state of nuclear matter with the effective Skyrme force and use cutoff and dimensional regulariz…
Recent progress towards a chiral effective field theory for the NN system
C. J. Yang, Bingwei Long
Since Weinberg's proposal two decades ago, chiral effective field theory in the NN sector has been developed and applied up to order . In principle it could provid…
Renormalizability of the nuclear many-body problem with the Skyrme interaction beyond mean field
C. J. Yang, M. Grasso, K. Moghrabi +1
Phenomenological effective interactions like Skyrme forces are currently used in mean--field calculations in nuclear physics. Mean--field models have strong analogies with the firs…
The longitudinal response function of the deuteron in chiral effective field theory
C. -J. Yang, Daniel R. Phillips
We use chiral effective field theory (EFT) to make predictions for the longitudinal electromagnetic response function of the deuteron, f_L, which is measured in d(e,e'N) reactions.…
Renormalizing Chiral Nuclear Forces: A Case Study of 3P0
Bingwei Long, C. -J. Yang
We discuss in this paper the subleading contact interactions, or counterterms, in the 3P0 channel of nucleon-nucleon scattering up to O(Q^3), where, already at leading order, Weinb…
