Light-wave Control of Non-equilibrium Correlated States using Quantum Femtosecond Magnetism and Time-Periodic Modulation of Coherent Transport
P. C. Lingos, M. D. Kapetanakis, J. Wang +1
Lightwave quantum electronics utilizes the oscillating carrier wave of intense laser fields to control quantum materials properties. Using quantum kinetic equations of motion, we d…
Theory of Ultrafast Spin--Charge Quantum Dynamics in Strongly Correlated Systems Controlled by Femtosecond Photoexcitation: an Application to Insulating Antiferromagnetic Manganites
P. C. Lingos, M. D. Kapetanakis, M. Mootz +2
We use a non-equilibrium many-body theory that engages the elements of transient coherence, correlation, and nonlinearity to describe changes in the magnetic and electronic phases…
All-optical four-state magnetization reversal in (Ga,Mn)As ferromagnetic semiconductors
M. D. Kapetanakis, P. C. Lingos, C. Piermarocchi +2
Using density matrix equations of motion and a tight-binding band calculation, we predict all-optical switching between four metastable magnetic states of (III,Mn)As ferromagnets.…
Femtosecond Coherent Control of Spin with Light in (Ga,Mn)As ferromagnets
M. D. Kapetanakis, I. E. Perakis, K. J. Wickey +2
Using density matrix equations of motion, we predict a femtosecond collective spin tilt triggered by nonlinear, near--ultraviolet (3eV), coherent photoexcitation of (Ga,Mn)As…
Magnetization Relaxation and Collective Spin Excitations in Correlated Double--Exchange Ferromagnets
M. D. Kapetanakis, I. E. Perakis
We study spin relaxation and dynamics of collective spin excitations in correlated double--exchange ferromagnets. For this, we introduce an expansion of the Green's functions equat…
Spin dynamics in (III,Mn)V ferromagnetic semiconductors: the role of correlations
M. D. Kapetanakis, I. E. Perakis
We address the role of correlations between spin and charge degrees of freedom on the dynamical properties of ferromagnetic systems governed by the magnetic exchange interaction be…
