Momentum-dependent power law measured in an interacting quantum wire beyond the Luttinger limit
Power laws are usually associated with a scale invariance due to the absence of a length scale. Here, Jin et al. report experimental evidence of a new type of power law in a GaAs/AlGaAs double quantum-well heterostructure, suggesting existence of a new type of universality that emerges at finite ene...

Power laws are usually associated with a scale invariance due to the absence of a length scale. Here, Jin et al. report experimental evidence of a new type of power law in a GaAs/AlGaAs double quantum-well heterostructure, suggesting existence of a new type of universality that emerges at finite energy and momentum. |
