A third-order exceptional point effect on the dynamics of a single particle in a time-dependent harmonic trap
Raam Uzdin, Emanuele Dalla Torre, Ronnie Kosloff +1
The time evolution of a single particle in a harmonic trap with time dependent frequency omega(t) is well studied. Nevertheless here we show that, when the harmonic trap is opened…
Time-dependent Hamiltonians with 100% evolution speed efficiency
Raam Uzdin, Uwe Guenther, Saar Rahav +1
The evolution speed in projective Hilbert space is considered for Hermitian Hamiltonians and for non-Hermitian (NH) ones. Based on the Hilbert-Schmidt norm and the spectral norm of…
Breakdown of adiabatic transfer of light in waveguides in the presence of absorption
Eva-Maria Graefe, Alexei A. Mailybaev, Nimrod Moiseyev
In atomic physics, adiabatic evolution is often used to achieve a robust and efficient population transfer. Many adiabatic schemes have also been implemented in optical waveguide s…
