DESCRIPTION:Speakers: Wade DeGottardi (Texas Tech University)\n\nLow-dimen
 sional quantum systems display collective behavior fundamentally different
  from that of ordinary matter. Electrons can separate into distinct spin a
 nd charge excitations\; insulators can conduct along their boundaries\; su
 perconducting systems can host non-Abelian Majorana modes\; and quantum cr
 itical systems can exhibit emergent symmetries and supersymmetries. While 
 traditional experimental probes can sometimes offer glimpses of this behav
 ior\, many of these predictions remain difficult to probe experimentally.R
 ecent experimental technologies\, particularly those developed for quantum
  computing\, are providing new tools to probe and simulate these systems. 
 In this talk\, I will describe our efforts to exploit these emerging capab
 ilities to reveal quantum many-body physics. I will first discuss how stro
 ng light-matter coupling can be used to generate and reveal quantum correl
 ations in one-dimensional electronic systems and how superconducting circu
 its can be used to probe and simulate many-body quantum states. I will the
 n turn to quantum-computing platforms themselves\, including quantum annea
 lers and digital quantum computers\, as platforms for studying coherent ma
 ny-body dynamics. In turn\, these simulations offer invaluable feedback ab
 out the coherence properties of the emerging NISQ (noisy intermediate-scal
 e quantum) technology landscape. Along the way\, I will highlight contribu
 tions from students and collaborators who have made this work possible.I w
 ill conclude by discussing future directions aimed at attacking longstandi
 ng questions in quantum many-body physics: how can emergent behavior and s
 ymmetries be directly probed? How can we approach strongly interacting sys
 tems when a simple quasiparticle description is no longer available? I wil
 l describe how fluorescence spectroscopy may provide signatures of emergen
 t symmetries and quantum critical behavior. I will also point to theoretic
 al and quantum-simulation approaches that may help us understand many-body
  dynamics beyond the quasiparticle paradigm. \n\nhttps://eventreg.ads.ttu
