Stimulated cooling in non-equilibrium Bose-Einstein condensate
Ka Kit Kelvin Ho, Vladislav Yu. Shishkov, Mohammad Amini +10
We report on the experimental observation of stimulated cooling in the non-equilibrium Bose-Einstein condensate (BEC) of weakly interacting exciton-polaritons from approximately ro…
Topological invariants and topological charges in photonic systems
Kristian Arjas, Grazia Salerno, Päivi Törmä
Topology in photonics comes in two distinct flavors: global and local. Global topology considers invariants that are obtained by integrating over the energy band, whereas local top…
Theory of Superconductivity in LaRuSi and Predictions of New Kagome Flat Band Superconductors
Junze Deng, Yi Jiang, Tiago F. T. Cerqueira +14
We present a comprehensive investigation of the flat-band kagome superconductor LaRuSi, which has recently been reported to host charge density wave (CDW) order above room…
Superconductivity and pair density waves from nearest-neighbor interactions in frustrated lattice geometries
Eeli O. Lamponen, Sofia K. Pöntys, Päivi Törmä
We consider superconductivity and pair density waves (PDWs) arising from off-site pairing in frustrated lattice geometries. We express the pair susceptibility in a generic form tha…
Quantum Geometry in Quantum Materials
Jiabin Yu, B. Andrei Bernevig, Raquel Queiroz +3
Quantum geometry, characterized by the quantum geometric tensor, is pivotal in diverse physical phenomena in quantum materials. In condensed matter systems, quantum geometry refers…
Cascade of pressure induced competing CDWs in the kagome metal FeGe
A. Korshunov, A. Kar, C. -Y. Lim +14
Electronic ordering is prevalent in correlated systems, which commonly exhibit competing interactions. Here, we use x-ray diffraction to demonstrate a cascade of pressure induced o…
