Enhanced Drude weight in a 1D system of fermions with pair hopping events
M. S. Bahovadinov, R. O. Sharipov, B. L. Altshuler +1
In one dimension density-density interactions of particles reduce their mobility and hence the Drude weight, which controls the divergence of the optical conductivity at zero frequ…

Tomonaga-Luttinger liquid-Bose glass phase transition in a system of 1D disordered fermions with pair hoppings
M. S. Bahovadinov, R. O. Sharipov, B. L. Altshuler +1
We consider a one-dimensional system of spinless fermions with single particle and pair hoppings in a potential on-site disorder. The pair hopping term violates integrability of th…
