Entangled Polariton States in the Visible and Mid-Infrared Spectral Ranges
Vladislav Yu. Shishkov, Oleg Kotov, Emily Haughton +5
Entanglement generation in polariton systems is fundamentally constrained by high losses and decoherence, which typically outweigh polariton nonlinearities. Here, we propose a conc…
Squeezing and quantum control of antiferromagnetic magnon pseudospin
Anna-Luisa E. Römling, Johannes Feist, Francisco J. GarcÃa-Vidal +1
Antiferromagnets have been shown to harbor strong magnon squeezing in equilibrium, making them a potential resource for quantum correlations and entanglement. Recent experiments ha…
General theory of cavity-mediated interactions between low-energy matter excitations
Carlos J. Sánchez MartÃnez, Frieder Lindel, Francisco J. GarcÃa-Vidal +1
The manipulation of low-energy matter properties such as superconductivity, ferromagnetism and ferroelectricity via cavity quantum electrodynamics engineering has been suggested as…
Taming the Bloch-Redfield equation: Recovering an accurate Lindblad equation for general open quantum systems
Diego Fernández de la Pradilla, Esteban Moreno, Johannes Feist
Master equations play a pivotal role in investigating open quantum systems. In particular, the Bloch-Redfield equation stands out due to its relation to a concrete physical environ…
Unconventional magnetism mediated by spin-phonon-photon coupling
Petros Andreas Pantazopoulos, Johannes Feist, Francisco J. GarcÃa-Vidal +1
Magnetic order typically emerges due to the short-range exchange interaction between the constituent electronic spins. Recent discoveries have found a crucial role for spin-phonon…
