Numerous correlated electron systems exhibit a strongly scale-dependent behavior. Upon
lowering the energy scale, collective phenomena, bound states, and new effective degrees …

The purpose of this review is to survey the status of the theory and experiment which can
contribute to our knowledge of plasmon excitations in synthetic semiconductor …

The description of solids at a microscopic level is complex, involving the interaction of a
huge number of its constituents, such as ions or electrons. It is impossible to solve the …

Motivated by recent experiments, we investigate the excitation energy of a proximitized
Rashba wire in the presence of a position dependent pairing. In particular, we focus on the …

The density matrix renormalization (DMRG) group method for ladders works much more
efficiently with open boundary conditions. One consequence of these boundary conditions is …

The presence of defects subtly alters all of a material's properties. Chemical reactivity,
mechanical strength, optical absorption, and electronic transport all vary with defect …

We derive the effective low-energy theory for single-wall carbon nanotubes including the
Coulomb interactions among electrons. The generic model found here consists of two spin …

We study a one-dimensional system of interacting spinless fermions subject to a localized
loss, where the interplay of gapless quantum fluctuations and particle interactions leads to …

These lectures provide a simple introduction to non perturbative methods of field theory in
1+ 1 dimensions, and their application to the study of strongly correlated condensed matter …

We discuss the effective interactions between two localized perturbations in one-
dimensional quantum liquids. For noninteracting fermions, the interactions exhibit Friedel …
