A microscopic approach to nonlinear theory of spin-charge separation
Oleksandr Tsyplyatyev, Yiqing Jin, María Moreno +2
The fate of spin-charge separation beyond the low energy remains elusive up to now. Here we develop a microscopic theory of the correlation functions using the strong coupling expa…
Dominant end-tunneling effect in two distinct Luttinger liquids coexisting in one quantum wire
Henok Weldeyesus, Pedro M. T. Vianez, Omid Sharifi Sedeh +10
Luttinger liquids occupy a special place in physics as the most understood case of essentially quantum many-body systems. The experimental mission of measuring its main prediction,…
Decoupling of the many-body effects from the electron mass in GaAs by means of reduced dimensionality
P. M. T. Vianez, Y. Jin, W. K. Tan +6
Determining the (bare) electron mass in crystals is often hindered by many-body effects since Fermi-liquid physics renormalises the band mass, making the observed effective m…
Microscopic metallic air-bridge arrays for connecting quantum devices
Y. Jin, M. Moreno, P. M. T. Vianez +5
We present a single-exposure fabrication technique for a very large array of microscopic air-bridges using a tri-layer resist process with electron-beam lithography. The technique…
Observing separate spin and charge Fermi seas in a strongly correlated one-dimensional conductor
P. M. T. Vianez, Y. Jin, M. Moreno +9
An electron is usually considered to have only one form of kinetic energy, but could it have more, for its spin and charge, by exciting other electrons? In one dimension (1D), the…
Momentum-dependent power law measured in an interacting quantum wire beyond the Luttinger limit
Y. Jin, O. Tsyplyatyev, M. Moreno +8
Power laws in physics have until now always been associated with a scale invariance originating from the absence of a length scale. Recently, an emergent invariance even in the pre…
Nature of the many-body excitations in a quantum wire: theory and experiment
O. Tsyplyatyev, A. J. Schofield, Y. Jin +8
The natural excitations of an interacting one-dimensional system at low energy are hydrodynamic modes of Luttinger liquid, protected by the Lorentz invariance of the linear dispers…
Hierarchy of modes in an interacting system
O. Tsyplyatyev, A. J. Schofield, Y. Jin +7
Studying interacting fermions in 1D at high energy, we find a hierarchy in the spectral weights of the excitations theoretically and we observe evidence for second-level excitation…
