Motivated by recent advances in quantum dynamics, we investigate the dynamics of the system with SU (1, 1) symmetry. Instead of performing the time-ordered integral for the …

The concept of contact interaction is fundamental in various areas of physics. It simplifies physical models by replacing the detailed short-range interaction with a zero-range contact …

We demonstrate the existence of exact Floquet flat bands implying strong violation of the eigenstate thermalization hypothesis in a large class of closed quantum many-body systems …
The Floquet time crystal, which breaks discrete time-translation symmetry, is an intriguing phenomenon in nonequilibrium systems. It is crucial to understand the rigidity and …
We consider the long-term weakly nonlinear evolution governed by the two-dimensional nonlinear Schrödinger (NLS) equation with an isotropic harmonic oscillator potential. The …
Two-dimensional Fermi gases with universal short-range interactions are known to exhibit a quantum anomaly, where a classical scale and conformal invariance is broken by quantum …
We show that quantum dynamics of any systems with SU (1, 1) symmetry are governed by the same underlying geometry of an anti-de Sitter spacetime in 2+ 1 dimensions (AdS 2+ 1) …
