Opening a gap in the dispersion of the collective excitations of a driven-dissipative condensate subject to an external coherent drive
E. Stazzu, G. A. P. Sacchetto, I. Carusotto
We build a minimal theoretical model to describe the opening of a gap in the dispersion of the collective excitations of a driven-dissipative condensate when the condensate phase i…
Cavity modification of magnetoplasmon mode through coupling with intersubband polaritons
Lucy L. Hale, Daniele De Bernardis, Stephan Lempereur +12
We investigate the coupling of a multi-mode metal-insulator-metal cavity to a two-dimensional electron gas (2DEG) in a quantum well in the presence of a strong magnetic field. The…
Unidirectional lasing in nonlinear Taiji micro-ring resonators
Alberto Muñoz de las Heras, Iacopo Carusotto
We develop a general formalism to study laser operation in active micro-ring resonators supporting two counterpropagating modes. Our formalism is based on the coupled-mode equation…
Refermionized theory of the edge modes of a fractional quantum Hall cloud
Alberto Nardin, Iacopo Carusotto
Making use of refermionization techniques, we map the nonlinear chiral Luttinger liquid model of the edge modes of a spatially confined fractional quantum Hall cloud developed in o…
Linear and nonlinear edge dynamics of trapped fractional quantum Hall droplets
Alberto Nardin, Iacopo Carusotto
We report numerical studies of the linear and nonlinear edge dynamics of a non-harmonically confined macroscopic fractional quantum Hall fluid. In the long-wavelength and weak exci…
Stimulated Hawking effect and quasinormal mode resonance in a polariton simulator of field theory on curved spacetime
Mattheus Burkhard, Malte Kroj, Kévin Falque +3
The Hawking effect amplifies fluctuations in the vicinity of horizons, both in black holes and in analogue platforms. Here, we consider a polariton simulator and numerically examin…
