Observing dissipationless flow of an impurity in a strongly repulsive quantum fluid
Milena Horvath, Sudipta Dhar, Elisabeth Wybo +6
The frictionless motion of an object through a fluid medium is commonly viewed as a hallmark of superfluidity. According to Landau, kinematic constraints prohibit superfluid behavi…
Experimental observation of conformal field theory spectra
Xiangkai Sun, Yuan Le, Stephen Naus +6
Conformal field theories (CFTs) feature prominently in high-energy physics, statistical mechanics, and condensed matter. For example, CFTs govern emergent universal properties of s…
Spectroscopy of Wigner crystal polarons in an atomically thin semiconductor
L. Wang, F. Menzel, F. Pichler +5
Strongly interacting electrons in two-dimensional systems can spontaneously break translational symmetry, forming a periodic Wigner crystal. Although these crystals have been reali…
Strong-to-weak symmetry breaking in monitored dipole conserving quantum circuits
Caterina Zerba, Sarang Gopalakrishnan, Michael Knap
We explore the information-theoretic phases of monitored quantum circuits subject to dynamics that conserves both charge and dipole moment, as well as measurements of the local cha…
Strong-to-Weak Symmetry Breaking Phases in Steady States of Quantum Operations
Niklas Ziereis, Sanjay Moudgalya, Michael Knap
Mixed states can exhibit two distinct kinds of symmetries, either on the level of the individual states (strong symmetry), or only on the level of the ensemble (weak symmetry). Str…
