Unraveling the Effect of Circularly Polarized Light on Reciprocal Media: Breaking Time Reversal Symmetry with Non-Maxwellian Magnetic-esque Fields
R. Merlin
Optical rectification of intense, circularly polarized light penetrating a material generates a static magnetic field aligned with the light's direction and proportional to its int…
Surface Phonons in the Topological Insulators Bi2Se3 and Bi2Te3
Ibrahim Boulares, Guangsha Shi, Emmanouil Kioupakis +2
Raman scattering [K. M. F. Shahil et al., Appl. Phys. Lett. 96, 153103 (2010), V. Gnezdilov et al., Phys. Rev. B 84, 195118 (2011) and H. H. Kung et al., Phys. Rev. B 95, 245406 (2…
A dynamical stability limit for the charge density wave in K0.3MoO3
Roman Mankowsky, Biaolong Liu, Srivats Rajasekaran +6
We study the response of the one-dimensional charge density wave in K0.3MoO3 to different types of excitation with femtosecond optical pulses. We compare the response to direct exc…
Real-time Observation of Phonon-Mediated - Interband Scattering in MgB2
Edoardo Baldini, Andreas Mann, Lara Benfatto +11
In systems having an anisotropic electronic structure, such as the layered materials graphite, graphene and cuprates, impulsive light excitation can coherently stimulate specific b…
Terahertz Spectrometer of Wavelength Dimensions Based on Extraordinary Transmission
Meredith Henstridge, J. Zhou, L. Jay Guo +1
Subwavelength-slotted parallel plate waveguides exhibit a localized electromagnetic resonance bound to the slits at a frequency slightly below the transverse electric cutoff [R. Me…
Exciton Beats in GaAs Quantum Wells: Bosonic Representation and Collective Effects
J. Fernandez-Rossier, C. Tejedor, R. Merlin
We discuss light-heavy hole beats observed in transient optical experiments in GaAs quantum wells in terms of a free-boson coherent state model. This approach is compared with desc…
Magnetic Raman Scattering in Two-Dimensional Spin-1/2 Heisenberg Antiferromagnets: Spectral Shape Anomaly and Magnetostrictive Effects
Franco Nori, Roberto Merlin, Stephan Haas +2
We calculate the Raman spectrum of the two-dimensional (2D) spin-1/2 Heisenberg antiferromagnet by exact diagonalization and quantum Monte Carlo techniques on clusters of up to 144…
