Entanglement and the density matrix renormalisation group in the generalised Landau paradigm
Laurens Lootens, Clement Delcamp, Frank Verstraete
The fields of entanglement theory and tensor networks have recently emerged as central tools for characterising quantum phases of matter. In this article, we determine the entangle…
Low-depth unitary quantum circuits for dualities in one-dimensional quantum lattice models
Laurens Lootens, Clement Delcamp, Dominic Williamson +1
A systematic approach to dualities in symmetric (1+1)d quantum lattice models has recently been proposed in terms of module categories over the symmetry fusion categories. By chara…
Dualities in one-dimensional quantum lattice models: topological sectors
Laurens Lootens, Clement Delcamp, Frank Verstraete
It has been a long-standing open problem to construct a general framework for relating the spectra of dual theories to each other. Here, we solve this problem for the case of one-d…
Dualities in one-dimensional quantum lattice models: symmetric Hamiltonians and matrix product operator intertwiners
Laurens Lootens, Clement Delcamp, Gerardo Ortiz +1
We present a systematic recipe for generating and classifying duality transformations in one-dimensional quantum lattice systems. Our construction emphasizes the role of global sym…
