DESCRIPTION:Consider some of the most basic questions in quantum mechanics 
 and its measurement via spectroscopy. One of the first questions in quantu
 m mechanics is whether to work in the position or momentum representation.
  Chemists working with molecules prefer position\, along with things like 
 potential energy surfaces and reaction coordinates. Physicists working wit
 h extended solids prefer momentum\, along with things like band structures
 . How to think about a mesoscopic material? In this case mesoscopic means 
 meso between macroscale and microscale – nanoscale materials like quantu
 m dots. In terms of measurement\, one can perform spectroscopy in either t
 he frequency domain or the time domain. Isolated molecules and perfect sol
 ids are generally studied in the frequency domain\, whereas disordered liq
 uids and glasses are generally studied in the time domain. What about the 
 meso scale in terms of order and disorder? How to measure and describe the
  new metal halide perovskites which have recently been shown to support li
 quid/solid duality ? These two fundamental and profound questions connecti
 ng Chemistry and Physics and Engineering and Materials Science will be dis
 cussed. We will use the full suite of our ultrafast laser spectroscopic to
 ols to explore some of the deepest ideas in liquid/solid duality in new ma
 terials.\n\nOur approach begins with time-resolved photoluminescence spect
 roscopy (t-PL) as a simple and intuitive method to reveal light emissive p
 roperties of materials. We then move to transient-absorption (TA) spectros
 copy to probe earlier time dynamics of excitons and phonons and polarons. 
 We ultimately move to two-dimensional electronic (2DE) spectroscopy to rev
 eal glimpses of the earliest dynamics\, many-body processes\, and coherent
  effects. In short\, we apply three world leading spectroscopies to unrave
 l some of the deepest questions of mesoscale materials for our optoelectro
 nic future.  \n\n \n\nDr. Patanjali Kambhampati is a Professor in the Depa
 rtment of Chemistry at McGill University and is an internationally recogni
 zed expert on semiconductor quantum dots and ultrafast laser science. He h
 as published over 80 papers with over 8000 citations. He has delivered inv
 ited departmental colloquia in over 50 institutions including. He has writ
 ten five invited review articles on the state of the field of quantum dots
 \, one invited white paper on laser science\, and has had six primary arti
 cles publicized in the media. Kambhampati has been awarded the McGill Univ
 ersity Fessenden Professorship as well as the Fessenden Prize (2012) for r
 esearch innovation towards commercialization activities\, followed by the 
 Wares Prize (2019). He was awarded a Lady Davis Visiting Professorship at 
 the Hebrew University in Jerusalem (2021). He was awarded the Polanyi Awar
 d of the Chemical Society of Canada (2022). He is on the International Adv
 isory Board of the Journal of Physical Chemistry Letters.
