Entanglement flow in the Kane-Fisher quantum impurity problem
Chunyu Tan, Yuxiao Hang, Stephan Haas +1
The problem of a local impurity in a Luttinger liquid, just like the anisotropic Kondo problem (of which it is technically a cousin), describes many different physical systems. As…
Superconductivity in the Fibonacci Chain
Ying Wang, Gautam Rai, Chris Matsumura +2
Superconductivity was recently reported in several quasicrystalline systems. These are materials which are structurally ordered, but since they are not translationally invariant, t…
Dynamics of Symmetry-Protected Topological Matter on a Quantum Computer
Miguel Mercado, Kyle Chen, Parth Darekar +3
Control of topological edge modes is desirable for encoding quantum information resiliently against external noise. Their implementation on quantum hardware, however, remains a lon…
Spatial BCS-BEC crossover in superconducting p-n junctions
A. Niroula, G. Rai, S. Haas +1
We present a theory of superconducting p-n junctions. We consider a 2-band model of doped bulk semiconductors with attractive interactions between the charge carriers and derive th…
Disordered Quantum Spin Chains with Long-Range Antiferromagnetic Interactions
N. Moure, Hyun-Yong Lee, S. Haas +2
We investigate the magnetic susceptibility of quantum spin chains of spins with power-law long-range antiferromagnetic coupling as a function of their spatial decay…
Interplay of screening and superconductivity in low-dimensional materials
G. Schönhoff, M. Rösner, R. Groenewald +2
A quantitative description of Coulomb interactions is developed for two-dimensional superconducting materials, enabling us to compare intrinsic with external screening effects, suc…
