Hood Lab

Purdue Ultracold Molecule Lab

Welcome to the Hood lab at Purdue.
We create ultracold molecules for quantum chemistry
and quantum simulation.


Welcome to the Hood ultracold atom and molecule lab at Purdue.  Our experimental group started in the spring of 2020.  We are in both the Department of Chemistry and the Department of Physics and Astronomy.  Our goal is to trap single atoms and molecules with optical tweezers in ultrahigh vacuum chambers. Find more about our research here

We are looking for enthusiastic graduate students, postdocs, and undergraduates.  Come help build a new quantum science lab!  If you are interested, email hoodjd@purdue.edu. 












October 2021: First Cs Raman signal


 September 2021: Three new graduate students 

Three new 1st year graduate students joined the group.  Christian and Emma are starting a new quantum optics experiment using an organic molecule as a quantum emitter.    Saumitra is joining the ultracold molecule experiment. 


 August 2021: First DBT Fluorescence!


 March 2021: First single atom! 

We have trapped a single Cs atom in an optical tweezer.  The micron size optical tweezer picks out a single atom from the magneto-optical trap.  The flickering is the atom coming into the trap, and then being kicked out by collisions with background gas.


 And welcome to our new visiting scholar, Maria.














January 2021: First magneto-optical trap! 

We created a cesium magneto-optical trap.  The white dot in the center of the glass cell is a cloud of 105 cesium atoms at a temperature of 200µK.  The cesium atoms are trapped by 6 laser beams and a magnetic field gradient inside an ultrahigh vacuum chamber glass cell (10-10  Torr).  The magnetic field gradient is made by the orange coils in the right picture. 














December 2020: Pumping down vacuum chamber 

Assembling, baking, and pumping the vacuum chamber down to ultrahigh vacuum  (<10-10  Torr).

October 2020: Cesium lasers are locked

Using cesium saturation absorption spectroscopy to lock a diode laser to the cesium transition.  Laser will be used for the magneto-optical trap.
