Absence of a Superradiant Phase Transition in Dirac Landau Polaritons
Elsa Jöchl, Felix Helmrich, Frieder Lindel +6
One of the most striking predictions in cavity quantum electrodynamics is the condensation of photons into a macroscopically populated ground state, the so-called superradiant phas…
Cavity-Driven Attractive Interactions in Quantum Materials
F. Helmrich, H. S. Adlong, I. Khanonkin +5
Many-body phenomena in quantum materials emerge from the interplay among a broad continuum of electronic states, and controlling these interactions is critical for engineering nove…
Optical Stabilization of Fluctuating High Temperature Ferromagnetism in YTiO
A. S. Disa, J. Curtis, M. Fechner +9
In quantum materials, degeneracies and frustrated interactions can have a profound impact on the emergence of long-range order, often driving strong fluctuations that suppress func…
Vibrational coherent control of localized d-d electronic excitation
Alexandre Marciniak, Stefano Marcantoni, Francesca Giusti +10
Addressing the role of quantum coherence in the interplay between the different matter constituents (electrons, phonons and spin) is a critical step towards understanding transitio…
Polarizing an antiferromagnet by optical engineering of the crystal field
Ankit S. Disa, Michael Fechner, Tobia F. Nova +5
Strain engineering is widely used to manipulate the electronic and magnetic properties of complex materials. An attractive route to control magnetism with strain is provided by the…
Metastable ferroelectricity in optically strained
Tobia Nova, Ankit Disa, Michael Fechner +1
Fluctuating orders in solids are generally considered high-temperature precursors of broken symmetry phases. However, in some cases these fluctuations persist to zero temperature a…
Parametric amplification of optical phonons
Andrea Cartella, Tobia Federico Nova, Michael Fechner +2
Amplification of light through stimulated emission or nonlinear optical interactions has had a transformative impact on modern science and technology. The amplification of other bo…
An effective magnetic field from optically driven phonons
T. F. Nova, A. Cartella, A. Cantaluppi +6
Light fields at THz and mid-infrared frequencies allow for the direct excitation of collective modes in condensed matter, which can be driven to large amplitudes. For example, exci…
