Prethermal fragmentation in a periodically driven Fermionic chain
Somsubhra Ghosh, Indranil Paul, K. Sengupta
We study a Fermionic chain with nearest-neighbor hopping and density-density interactions, where the nearest-neighbor interaction term is driven periodically. We show that such a d…
Superradiant phononic emission from the analog spin ergoregion in a two-component Bose-Einstein condensate
Anna Berti, Luca Giacomelli, Iacopo Carusotto
We make use of an analog gravity perspective to obtain a physical understanding of hydrodynamic instabilities stemming from the presence of quantized vortices in two-component atom…
Disentangling lattice and electronic instabilities in the excitonic insulator candidate TaNiSe by nonequilibrium spectroscopy
Kota Katsumi, Alexandr Alekhin, Sofia-Michaela Souliou +7
TaNiSe is an excitonic insulator candidate showing the semiconductor/semimetal-to-insulator (SI) transition below = 326 K. However, since a structural transi…
Achieving one-dimensionality with attractive fermions
F Chevy, G Orso
In this article we discuss the accuracy of effective one-dimensional theories used to describe the behavior of ultracold atomic ensembles confined in quantum wires by a harmonic tr…
Observation of edge magnetoplasmon squeezing in a quantum Hall conductor
H. Bartolomei, R. Bisognin, H. Kamata +10
Squeezing of the quadratures of the electromagnetic field has been extensively studied in optics and microwaves. However, previous works focused on the generation of squeezed state…
Supermoiré low-energy effective theory of twisted trilayer graphene
Yuncheng Mao, Daniele Guerci, Christophe Mora
Stacking three monolayers of graphene with a twist generally produces two moiré patterns. A moiré of moiré structure then emerges at larger distance where the three layers periodic…
