Analytically solvable quasi-one-dimensional Kronig-Penney model
Marta Sroczyńska, Tomasz Wasak, Zbigniew Idziaszek
We generalize the textbook Kronig-Penney model to realistic conditions for a quantum-particle moving in the quasi-one-dimensional (quasi-1D) waveguide, where motion in the transver…
A strong Bell correlation witness between spatially separated pairs of atoms
D. K. Shin, B. M. Henson, S. S. Hodgman +3
The violation of a Bell inequality is a striking demonstration of how quantum mechanics contradicts local realism. Although the original argument was presented with a pair of spin…
Magnetic-field gradiometer based on ultracold collisions
Tomasz Wasak, Krzysztof Jachymski, Tommaso Calarco +1
We present a detailed analysis of the usefulness of ultracold atomic collisions for sensing the strength of an external magnetic field as well as its spatial gradient. The core ide…
Quantum state engineering with a trapped atom and a set of static impurities
Marta Sroczyńska, Tomasz Wasak, Krzysztof Jachymski +2
Hybrid systems of ultracold atoms and trapped ions or Rydberg atoms can be useful for quantum simulation purposes. By tuning the geometric arrangement of the impurities it is possi…
Single-atom transistor as a precise magnetic field sensor
Krzysztof Jachymski, Tomasz Wasak, Zbigniew Idziaszek +3
Feshbach resonances, which allow for tuning the interactions of ultracold atoms with an external magnetic field, have been widely used to control the properties of quantum gases. W…
Criteria for particle entanglement in many-body systems of bosons
T. Wasak, P. Szankowski, M. Trippenbach +1
Basing on the analogy between the coherent states of light and separable states of bosons, we demonstrate that the violation Cauchy-Schwarz inequality for any-order correlation…
