Self-Pinning Transition of a Tonks-Girardeau Gas in a Bose-Einstein Condensate
Tim Keller, Thomás Fogarty, Thomas Busch
We show that a Tonks-Girardeau (TG) gas that is immersed in a Bose-Einstein condensate can undergo a transition to a crystal-like Mott state with regular spacing between the atoms…

Adiabatic critical quantum metrology cannot reach the Heisenberg limit even when shortcuts to adiabaticity are applied
Karol Gietka, Friederike Metz, Tim Keller +1
We show that the quantum Fisher information attained in an adiabatic approach to critical quantum metrology cannot lead to the Heisenberg limit of precision and therefore regular q…
