Constructing Effective Interactions via Projection-Based Inversion
Hang Yu, Serdar Elhatisari, Sebastian König +3
We present a numerical prescription for extracting continuum scattering information from discrete spectra by constraining effective interactions inspired by effective field theory…
Geometric factors in the volume dependence of many-body bound states
Hang Yu
I derive the volume dependence of bound states from a cluster-cluster picture with nucleon degrees of freedom. A constant factor called the geometric factor appears in the generali…
Impact of on-site potentials on -breathers in nonlinear chains
Lin Deng, Chengguan Fang, Hang Yu +5
On-site potentials are ubiquitous in physical systems and strongly influence their heat transport and energy localization. These potentials will inevitably affect the dynamical pro…
An Efficient Learning Method to Connect Observables
Hang Yu, Takayuki Miyagi
Constructing fast and accurate surrogate models is a key ingredient for making robust predictions in many topics. We introduce a new model, the Multiparameter Eigenvalue Problem (M…
-Breathers in the diatomic -Fermi-Pasta-Ulam- Tsingou chains
Lin Deng, Hang Yu, Zhigang Zhu +3
-Breathers (QBs) represent a quintessential phenomenon of energy localization, manifesting as stable periodic orbits exponentially localized in normal mode space. Their existenc…
Complex scaling in finite volume
Hang Yu, Nuwan Yapa, Sebastian König
Quantum resonances, i.e., metastable states with a finite lifetime, play an important role in nuclear physics and other domains. Describing this phenomenon theoretically is general…
