Sub-Shot-Noise Magnetometry with a Correlated Spin-Relaxation Dominated Alkali-Metal Vapor
I. K. Kominis
Spin noise sets fundamental limits to the precision of measurements using spin-polarized atomic vapors, such as performed with sensitive atomic magnetometers. Spin squeezing offers…
Negative Energy Resonances of Bosons in a Magnetic Quadrupole Trap
Shahpoor Saeidian, Igor Lesanovsky, Peter Schmelcher
We investigate resonances of spin 1 bosons in a three-dimensional magnetic quadrupole field. Complementary to the well-known positive energy resonances it is shown that there exist…
Controlling ultracold Rydberg atoms in the quantum regime
Bernd Hezel, Igor Lesanovsky, Peter Schmelcher
We discuss the properties of Rydberg atoms in a magnetic Ioffe-Pritchard trap being commonly used in ultracold atomic physics experiments. The Hamiltonian is derived and it is demo…
Manipulation of ultracold atoms in dressed adiabatic radio frequency potentials
I. Lesanovsky, S. Hofferberth, J. Schmiedmayer +1
We explore properties of atoms whose magnetic hyperfine sub-levels are coupled by an external magnetic radio frequency (rf) field. We perform a thorough theoretical analysis of thi…
