Fast collisional gate for fermionic atoms in an optical superlattice
Rafi Weill, Jonathan Nemirovsky, Yoav Sagi
Collisional gates in optical superlattices have recently achieved record fidelities, but their operation times are typically limited by tunneling. Here we propose and analyze an al…
Atomic interferometer based on optical tweezers
Jonathan Nemirovsky, Rafi Weill, Ilan Meltzer +1
Atomic interferometers measure forces and acceleration with exceptional precision. The conventional approach to atomic interferometry is to launch an atomic cloud into a ballistic…
Generalization of Kirchhoff's Law of Thermal Radiation: The Inherent Relations Between Quantum Efficiency and Emissivity
M. Kurtulik, M. Shimanovic, T. Bar Lev +4
Planck's law of thermal radiation depends on the temperature, , and the emissivity, , of a body, where emissivity is the coupling of heat to radiation that depends on both ph…
Spatial adiabatic passage of ultracold atoms in optical tweezers
Yanay Florshaim, Elad Zohar, David Zeev Koplovich +5
Spatial adiabatic passage (SAP) is a process that facilitates the transfer of a wave packet between two localized modes that are not directly coupled, but rather interact through a…
Generalization of Kirchhoff's Law: The inherent relations between quantum efficiency and emissivity
Matej Kurtulik, Michal Shimanovich, Rafi Weill +3
Planck's law of thermal radiation depends only on the temperature T and emissivity . It is one of the most fundamental discoveries about light-matter interaction that…
High-temperature photoluminescence reveals the inherent relations between quantum efficiency and emissivity
Matej Kurtulik, Rafi Weill, Assaf Manor +1
Photoluminescence (PL) is a light-matter quantum interaction associated with the chemical potential of light formulated by the Generalized Planck's law. Without knowing the inheren…
Temperature-dependent photoluminescence: A theoretical study
Matej Kurtulik, Assaf Manor, Rafi Weill +1
Photoluminescence (PL) is a light matter quantum interaction associated with the chemical potential of light formulated by the Generalized Planck's law. Without knowing the inheren…
Thermalization of one-dimensional photon gas and thermal lasers in erbium-doped fibers
Rafi Weill, Alexander Bekker, Boris Levit +2
We demonstrate thermalization and Bose-Einstein (BE) distribution of photons in standard erbium-doped fibers (edf) in a broad spectral range up to ~200nm at the 1550nm wavelength r…
When does lasing become a condensation phenomenon?
Baruch Fischer, Rafi Weill
We present a generic classical light condensation (LC) phenomenon in linear photonic mode systems, such as cw laser cavities, in a noisy environment (spontaneous emission, etc.), b…
Spectral Sidebands and Multi-Pulse Formation in Passively Mode Locked Lasers
Rafi Weill, Alexander Bekker, Vladimir Smulakovsky +2
Pulse formation in passively mode locked lasers is often accompanied with dispersive waves that form of spectral sidebands due to spatial inhomogoneities in the laser cavity. Here…
Critical Behavior of Light
Rafi Weill, Amir Rosen, Ariel Gordon +2
Light is shown to exhibit critical and tricritical behavior in passive mode-locked lasers with externally injected pulses. It is a first and unique example of critical phenomena in…
Formation and annihilation of laser light pulse quanta in thermodynamic-like pathway
Boris Vodonos, Rafi Weill, Ariel Gordon +4
We present a theoretical and experimental study of multiple pulse formation in passively mode-locked (PML) lasers. Following a statistical mechanics approach, the study yields a th…
