Not all doped Mott insulators have a pseudogap: key role of van Hove singularities
Wei Wu, Mathias S. Scheurer, Michel Ferrero +1
The Mott insulating phase of the parent compounds is frequently taken as starting point for the underdoped high- cuprate superconductors. In particular, the pseudogap state is…
Modes and states in Quantum Optics
Claude Fabre, Nicolas Treps
A few decades ago, quantum optics stood out as a new domain of physics by exhibiting states of light with no classical equivalent. The first investigations concerned single photons…
Role of charge transfer in hybridization-induced spin transition in metal-organic molecules
Jakob Steinbauer, Silke Biermann, Sumanta Bhandary
The spin-crossover in organometallic molecules constitutes one of the most promising routes towards the realization of molecular spintronic devices. In this article, we explore the…
Superfluid ground state phase diagram of the two-dimensional Hubbard model in the emergent Bardeen-Cooper-Schrieffer regime
Fedor Šimkovic, Youjin Deng, Evgeny Kozik
In nonperturbative regimes, the superfluid instability in the two-dimensional Hubbard model can be described by an emergent BCS theory with small effective pairing constants. We co…
Versatile photonic entanglement synthesizer in the spatial domain
David Barral, Mattia Walschaers, Kamel Bencheikh +4
Multimode entanglement is an essential resource for quantum information in continuous-variable systems. Light-based quantum technologies will arguably not be built upon table-top b…
Molecular gas in distant brightest cluster galaxies
G. Castignani, F. Combes, P. Salomé +1
The stellar mass assembly of brightest cluster galaxies (BCGs) is still debated. We have observed in CO with the IRAM-30m two star forming BCGs belonging to SpARCS clusters, 3C 244…
