Truncated many-body dynamics of interacting bosons: A variational principle with error monitoring
Kang-Soo Lee, Uwe R. Fischer
We develop a method to describe the temporal evolution of an interacting system of bosons, for which the field operator expansion is truncated after a finite number of modes, i…

Emergence of a new pair-coherent phase in many-body quenches of repulsive bosons
Uwe R. Fischer, Kang-Soo Lee, Bo Xiong
We investigate the dynamical mode population statistics and associated first- and second-order coherence of an interacting bosonic two-mode model when the pair-exchange coupling is…
