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,…
Collective modes in the charge-density wave state of KMoO: The role of long-range Coulomb interactions revisited
Max O. Hansen, Yash Palan, Viktor Hahn +7
We re-examine the effect of long-range Coulomb interactions on the collective amplitude and phase modes in the incommensurate charge-density-wave ground state of quasi-one-dimensio…
Splitting of Fermi point of strongly interacting electrons in one dimension: A nonlinear effect of spin-charge separation
O. Tsyplyatyev
A system of one-dimensional electrons interacting via a short-range potential described by Hubbard model is considered in the regime of strong coupling using the Bethe ansatz appro…
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…
Semiconductor nanodevices as a probe of strong electron correlations
P. M. T. Vianez, O. Tsyplyatyev, C. J. B. Ford
Interactions between electrons in solids are often behind exciting novel effects such as ferromagnetism, antiferromagnetism and superconductivity. All these phenomena break away fr…
