Nonperturbative decay of bipartite discrete time crystals
Lennart Fernandes, Joseph Tindall, Dries Sels
We study prethermal time-crystalline order in periodically driven quantum Ising models on disorder-free decorated lattices. Using a tensor network ansatz for the state which reflec…
Analog Hawking radiation from a spin-sonic horizon in a two-component Bose-Einstein condensate
Anna Berti, Lennart Fernandes, Salvatore Giulio Butera +3
We theoretically study stimulated and spontaneous Hawking emission from an analog horizon for spin modes in a two-component Bose-Einstein condensate, both with and without a cohere…
Gaussian trajectory description of fragmentation in an isolated spinor condensate
Lennart Fernandes, Michiel Wouters, Jacques Tempere
Spin-1 Bose gases quenched to spin degeneracy exhibit fragmentation: the appearance of a condensate in more than one single-particle state. Due to its highly entangled nature, the…
Effect of segregation on inequality in kinetic models of wealth exchange
Lennart Fernandes, Jacques Tempere
Empirical distributions of wealth and income can be reproduced using simplified agent-based models of economic interactions, analogous to microscopic collisions of gas particles. B…
