A universal speed limit for spreading of quantum coherence

Autor: Martirosyan, Gevorg, Gazo, Martin, Etrych, Jiří, Fischer, Simon M., Morris, Sebastian J., Ho, Christopher J., Eigen, Christoph, Hadzibabic, Zoran

Discoveries of fundamental limits for the rates of physical processes, from the speed of light to the Lieb-Robinson bound for information propagation, are conceptual breakthroughs that often challenge our understanding of the underlying physics. Here

Universal quantum dynamics of Bose polarons

Autor: Etrych, Jiří, Martirosyan, Gevorg, Cao, Alec, Ho, Christopher J., Hadzibabic, Zoran, Eigen, Christoph

Predicting the emergent properties of impurities immersed in a quantum bath is a fundamental challenge that can defy quasiparticle treatments. Here, we measure the spectral properties and real-time dynamics of mobile impurities injected into a homoge

Energy-space random walk in a driven disordered Bose gas

Autor: Zhang, Yansheng, Martirosyan, Gevorg, Ho, Christopher J., Etrych, Jiří, Eigen, Christoph, Hadzibabic, Zoran

Motivated by the experimental observation [1] that driving a non-interacting Bose gas in a 3D box with weak disorder leads to power-law energy growth, $E \propto t^{\eta}$ with $\eta=0.46(2)$, and compressed-exponential momentum distributions that sh

Report

Observation of subdiffusive dynamic scaling in a driven and disordered Bose gas

Autor: Martirosyan, Gevorg, Ho, Christopher J., Etrych, Jiří, Zhang, Yansheng, Cao, Alec, Hadzibabic, Zoran, Eigen, Christoph

Publikováno v: Phys. Rev. Lett. 132, 113401 (2024)

We explore the dynamics of a tuneable box-trapped Bose gas under strong periodic forcing in the presence of weak disorder. In absence of interparticle interactions, the interplay of the drive and disorder results in an isotropic nonthermal momentum d
