Ladder-like optical conductivity in the spin-fermion model
Laura Classen, Neil J. Robinson, Alexei M. Tsvelik
In the nested limit of the spin-fermion model for the cuprates, one-dimensional physics in the form of half-filled two-leg ladders emerges. We show that the renormalization group f…
Characterizing the quantum field theory vacuum using temporal Matrix Product states
Emanuele Tirrito, Neil J. Robinson, Maciej Lewenstein +2
In this paper we construct the continuous Matrix Product State (MPS) representation of the vacuum of the field theory corresponding to the continuous limit of an Ising model. We do…
Structure of eta' mesonic nuclei in a relativistic mean field theory
Daisuke Jido, Hanayo Masutani, Satoru Hirenzaki
The structure and the energy spectrum of the mesonic nuclei are investigated in a relativistic mean field theory. One expects a substantial attraction for the $η^{\pri…
Non-Topological Majorana Zero Modes in Inhomogeneous Spin Ladders
Neil J. Robinson, Alexander Altland, Reinhold Egger +6
We show that the coupling of homogeneous Heisenberg spin-1/2 ladders in different phases leads to the formation of interfacial zero energy Majorana bound states. Unlike Majorana bo…
Nonthermal states arising from confinement in one and two dimensions
Andrew J. A. James, Robert M. Konik, Neil J. Robinson
We show that confinement in the quantum Ising model leads to nonthermal eigenstates, in both continuum and lattice theories, in both one (1D) and two dimensions (2D). In the ordere…
