Nucleon-nucleon potentials evolved to low momentum, which show great promise in fewand many-body calculations, have generally been formulated with a sharp cutoff on relative momenta. However, a sharp cutoff has technical disadvantages and can cause convergence problems at the 10–100 keV level in the deuteron and triton. This motivates using smooth momentum-space regulators as an alternative. We...

With the advent of realistic nucleon-nucleon interactions, which reproduce the experimental NN scattering phase shifts and deuteron properties with high precision, the importance of three-body interactions became evident. Ab initio solutions of the nuclear many-body problem for p-shell nuclei, e.g. in the framework of Green’s Function Monte Carlo or no-core shell model approaches, have demonstr...

Cold Rydberg atoms subject to long-range dipole-dipole interactions represent a particularly interesting system for exploring few-body interactions and probing the transition from 2-body physics to the many-body regime. In this work we report the direct observation of a resonant 4-body Rydberg interaction. We exploit the occurrence of an accidental quasicoincidence of a 2-body and a 4-body reso...

Many people experience vibration effects on whole-body throughout their lives frequently. Vibrating energy absorbed is exposed all-body caused with vibration hazard in the vertically on body and biodynamic responses from body in speed 2.37 to 5.14 m/s could captivate with car seat on user body, so the vibration energy transferred to a seated people body. In this paper, the human body is modeled...

Many-body localization (MBL) is a mechanism by which quantum chains with strong enough disorder can avoid thermalization. Here, the authors define and locate several distinct landmarks having to do thermalization, rare many-body resonances, so-called thermal avalanches in systems that exhibit MBL. These are well separated strength of disorder, estimate where MBL breaks down asymptotically large...
