Ultrafocused Electromagnetic Field Pulses with a Hollow Cylindrical Waveguide
P. Maurer, J. Prat-Camps, J. I. Cirac +2
We theoretically show that an externally driven dipole placed inside a cylindrical hollow waveguide can generate a train of ultrashort and ultrafocused electromagnetic pulses. The…
Cooperative Effects in Closely Packed Quantum Emitters with Collective Dephasing
B. Prasanna Venkatesh, M. L. Juan, O. Romero-Isart
In a closely packed ensemble of quantum emitters, cooperative effects are typically suppressed due to the dephasing induced by the dipole-dipole interactions. Here, we show that by…
Quantum Spin Stabilized Magnetic Levitation
Cosimo C. Rusconi, Vera Pöchhacker, Katja Kustura +2
We theoretically show that, despite Earnshaw's theorem, a non-rotating single magnetic domain nanoparticle can be stably levitated in an external static magnetic field. The stabili…
Linear Stability Analysis of a Levitated Nanomagnet in a Static Magnetic Field: Quantum Spin Stabilized Magnetic Levitation
Cosimo C. Rusconi, Vera Pöchhacker, J. Ignacio Cirac +1
We theoretically study the levitation of a single magnetic domain nanosphere in an external static magnetic field. We show that apart from the stability provided by the mechanical…
