Fluctuations of squeezing fields beyond the Tomonaga--Luttinger liquid paradigm
Kazuma Nagao, Ludwig Mathey
The concept of Tomonaga--Luttinger liquids (TLL) on the basis of the free-boson models is ubiquitous in theoretical descriptions of low-energy properties in one-dimensional quantum…
Observation of a dissipative time crystal
Hans Keßler, Phatthamon Kongkhambut, Christoph Georges +3
The formation of a phase of matter can be associated with the spontaneous breaking of a symmetry. For crystallization, this broken symmetry is the spatial translation symmetry, as…
Higgs mode mediated enhancement of interlayer transport in high- cuprate superconductors
Guido Homann, Jayson G. Cosme, Junichi Okamoto +1
We put forth a mechanism for enhancing the interlayer transport in cuprate superconductors, by optically driving plasmonic excitations along the axis with a frequency that is b…
Collective modes and superfluidity of a two-dimensional ultracold Bose gas
Vijay Pal Singh, Ludwig Mathey
The collective modes of a quantum liquid shape and impact its properties profoundly, including its emergent phenomena such as superfluidity. Here we present how a two-dimensional B…
Dynamical control of the conductivity of an atomic Josephson junction
Beilei Zhu, Vijay Pal Singh, Junichi Okamoto +1
We propose to dynamically control the conductivity of a Josephson junction composed of two weakly coupled one dimensional condensates of ultracold atoms. A current is induced by a…
Three-body bound states of an atom in a Fermi mixture
Ali Sanayei, Ludwig Mathey
We determine the three-body bound states of an atom in a Fermi mixture. Compared to the Efimov spectrum of three atoms in vacuum, we show that the Fermi seas deform the Efimov spec…
