On the emergence of quantum many-body chaos for tunably-broken integrability
Sounak Biswas, Sthitadhi Roy, Roderich Moessner
We develop a quantitative theory for the emergence of quantum many-body chaos as integrability is broken via a tunable parameter. In a circuit model of free fermions, 'doped' with…
Minimal Hubbard models of maximal Hilbert space fragmentation
Yves H. Kwan, Patrick H. Wilhelm, Sounak Biswas +1
We show that Hubbard models with nearest-neighbor hopping and a nearest-neighbor hardcore constraint exhibit `maximal' Hilbert space fragmentation in many lattices of arbitrary dim…
Discrete scale invariant fixed point in a quasiperiodic classical dimer model
Sounak Biswas, S. A. Parameswaran
We study close-packed dimers on the quasiperiodic Ammann-Beenker (AB) graph, that was recently shown to have the unusual feature that hard-core dimer constraints are exactly reprod…
Compression theory for inhomogeneous systems
Doruk Efe Gökmen, Sounak Biswas, Sebastian D. Huber +3
The physics of complex systems stands to greatly benefit from the qualitative changes in data availability and advances in data-driven computational methods. Many of these systems…
Beyond the Freshman's Dream: Classical fractal spin liquids from matrix cellular automata in three-dimensional lattice models
Sounak Biswas, Yves H. Kwan, S. A. Parameswaran
We construct models hosting classical fractal spin liquids on two realistic three-dimensional (3D) lattices of corner-sharing triangles: trillium and hyperhyperkagome (HHK). Both m…
Statistical mechanics of dimers on quasiperiodic Ammann-Beenker tilings
Jerome Lloyd, Sounak Biswas, Steven H. Simon +2
We study classical dimers on two-dimensional quasiperiodic Ammann-Beenker (AB) tilings. Despite the lack of periodicity we prove that each infinite tiling admits 'perfect matchings…
Dulmage-Mendelsohn percolation: Geometry of maximally-packed dimer models and topologically-protected zero modes on site-diluted bipartite lattices
R. Bhola, S. Biswas, Md M. Islam +1
The classic combinatorial construct of {\em maximum matchings} probes the random geometry of regions with local sublattice imbalance in a site-diluted bipartite lattice. We demonst…
Singular ferromagnetic susceptibility of the transverse-field Ising antiferromagnet on the triangular lattice
Sounak Biswas, Kedar Damle
A transverse magnetic field is known to induce antiferromagnetic three-sublattice order of the Ising spins in the triangular lattice Ising antiferromagnet at low enough t…
