The LAMP group explores light-matter interactions through experimental, numerical and theoretical methods.

Various states of matter in a diversity of compositions - atoms, molecules, ions, solid-state materials and fabricated novel materials - are actively used in these investigations. The interactions are studied at very high temperatures, room temperature and in the very cold, including at extremely low temperatures, attained by laser cooling methods. Various forms of Laser sources are used in these studies ranging from very narrow line-width lasers with hundreds of milliwatts of power to high intensity pulsed lasers with pulse duration as small as a hundred femtoseconds.

The scientific endeavor of the group is centered on utilizing the very nature of light-matter interactions to study quantum and classical aspects of matter, their interactions with light and the quantum nature of light itself.

The research focus of the group is in:

  • Demonstration of quantum logic using ultra-cold atoms loaded in optical lattices and various kinds of nano-traps.
  • Investigation of transport and localization properties of light in random media.
  • Ultrafast laser induced plasmas from solid targets.
  • Nonlinear optical properties of nanomaterials.
  • Laser cooling and trapping of atoms.
  • Quantum Non-demolition (QND) measurements of quantum superposition states.
  • Creation and manipulation of quantum correlations and their transfer from photons to material objects like dilute collections of atoms to more solid state objects like a micromechanical spring.
  • Electromagnetically induced transparency and other related phenomena both from a theoretical and experimental point of view.
  • Manufacture of single photon sources based on spontaneous parametric down-conversion and their applications to fundamental tests of quantum mechanics, quantum information and computing and quantum communication.
  • Cold molecule production, trapping, detection and manipulation.
  • Ion trapping.
  • Cold collisions between cold atoms, ions and molecules.
  • Atoms in cavities.
  • Response of atoms to external fields.
  • Chemical processes at ultra-cold temperatures.
  • Quantum optics with neutral atoms and non-classical light sources.
