DOI: 10.1007/s00220-018-3156-2
Abstract: We study the ground state of a large bosonic system trapped in a symmetric double-well potential, letting the distance between the two wells increase to infinity with the number of particles. In this context, one… read more here.

DOI: 10.1007/s12204-020-2238-4
Abstract: Bearing incipient fault characteristics are always submerged in strong background noise with weak fault characteristics, so that the incipient fault is hard to detect. Stochastic resonance (SR) is accepted to be an effective way to… read more here.

DOI: 10.1021/acs.jctc.2c00030
Abstract: Simulating vibrationally resolved electronic spectra of anharmonic systems, especially those involving double-well potential energy surfaces, often requires expensive quantum dynamics methods. Here, we explore the applicability and limitations of the recently proposed single-Hessian thawed Gaussian… read more here.
