Long-Range Interactions in Weyl-Dense Atomic Arrays Protected from Dissipation and Disorder

Marcelo Castellanos2025-04-29T11:13:08+02:00Tags: Multidisciplinary. , Physics|

Authors: Garcia-Elcano, Inaki; Huidobro, Paloma A.; Bravo-Abad, Jorge; Gonzalez-Tudela, Alejandro Journal: PHYSICAL REVIEW LETTERS Publication date: 2025/03/28 DOI: 10.1103/PhysRevLett.134.123602 Abstract: Long-range interactions are a key resource in many quantum phenomena and technologies. Free-space photons mediate power-law interactions but lack tunability and suffer from decoherence processes due to their omnidirectional emission. Engineered dielectrics can yield tunable [...]

Exact Quantization of Nonreciprocal Quasilumped Electrical Networks

Authors: Parra-Rodriguez, A.; Egusquiza, I. L. Journal: PHYSICAL REVIEW X Publication date: 2025/03/28 DOI: 10.1103/PhysRevX.15.011072 Abstract: Following a consistent geometrical description previously introduced [Quantum 8, 1466 (2024)], we present an exact method for obtaining canonically quantizable Hamiltonian descriptions of nonlinear, nonreciprocal quasilumped electrical networks. We identify and classify singularities arising in the quest for Hamiltonian [...]

Dipole-dipole interactions mediated by a photonic flat band

Authors: Di Benedetto, Enrico; Gonzalez-Tudela, Alejandro; Ciccarello, Francesco Journal: QUANTUM Publication date: 2025/03/25 DOI: Abstract: Flat bands (FBs) are energy bands with zero group velocity, which in electronic systems were shown to favor strongly correlated phenomena. Indeed, a FB can be spanned with a basis of strictly localized states, the so called compact localized states [...]
