SUMMARY:Shortcuts to adiabaticity using flow-fields
DESCRIPTION:Featuring Ayoti Patra\, Maryland\n\nPart of the Condensed Matte
	r Theory Seminar Series.\n\nAdiabatic invariants – quantities that are pr
	eserved under the slow driving of a system’s external parameters – are 
	important in classical mechanics\, quantum mechanics and thermodynamics. Sh
	ortcuts to adiabaticity are strategies for preserving adiabatic invariants 
	even under rapid driving. One such strategy utilizes an auxiliary counterdi
	abatic term to suppress the non-adiabatic excitations arising due to rapid 
	driving. I will describe a unified framework for obtaining counterdiabatic 
	terms  using flow-fields. In the flow-fields approach\, an appropriate inte
	grated function (IF) is first defined. The flow-field parameters namely the
	 velocity and acceleration are derived from the IF. Counterdiabatic terms c
	an then be constructed using simple equations involving the flow-field para
	meters. I will illustrate that the flow-fields framework provides 'shortcut
	s' for quantum\, classical as well as stochastic systems.
