Swinging small quantum systems out of available values of control parameters
Xikun Li, Tomasz Sowiński
When a quantum system is prepared in its many-body ground state, it can be adiabatically driven to another ground state by changing its control parameter. However, relying on adiab…

Lissajous dynamics of a quantum particle in a tilted two-dimensional discrete lattice
Grzegorz Jaczewski, Tomasz Sowiński
The quantum dynamics of a single particle in a discrete two-dimensional tilted lattice is analyzed from the perspective of the classical-quantum correspondence. Utilizing the fact…

Universality of internal correlations of strongly interacting p-wave fermions in one-dimensional geometry
Przemysław Kościk, Tomasz Sowiński
We consider the many-body ground state of polarized fermions interacting via zero-range -wave forces in a one-dimensional geometry. We rigorously prove that in the li…
