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…
Classification of spin- fermionic quantum spin liquids on the trillium lattice
Ming-Hao Li, Sounak Biswas, S. A. Parameswaran
We study fermionic quantum spin liquids (QSLs) on the three-dimensonal trillium lattice of corner-sharing triangles. We are motivated by recent experimental and theoretical investi…
Reflectionless propagation of beams through a stratified medium
Sounak Sinha Biswas, Ghanasyam Remesh, Venu Gopal Achanta +3
Reflectionless potentials following the prescription of Kay and Moses allow for total transmission of incoming waves of any kinetic energy. The optical analogue of such potentials…
Quantum Fisher information in a strange metal
Federico Mazza, Sounak Biswas, Xinlin Yan +5
A strange metal is an exotic state of correlated quantum matter; intensive efforts are ongoing to decipher its nature. Here we explore whether the quantum Fisher information (QFI),…
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…
Enhanced beam shifts mediated by Bound States in Continuum
Sounak Sinha Biswas, Ghanasyam Remesh, Venu Gopal Achanta +3
The interaction of light beams with resonant structures has led to the development of various optical platforms for sensing, particle manipulation, and strong light-matter interact…
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…
Hydrodynamic non-linear response of interacting integrable systems
Michele Fava, Sounak Biswas, Sarang Gopalakrishnan +2
We develop a formalism for computing the non-linear response of interacting integrable systems. Our results are asymptotically exact in the hydrodynamic limit where perturbing fiel…
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…
Efficient quantum cluster algorithms for frustrated transverse field Ising antiferromagnets and Ising gauge theories
Sounak Biswas, Kedar Damle
Working within the Stochastic Series Expansion (SSE) framework, we construct efficient quantum cluster algorithms for transverse field Ising antiferromagnets on the pyrochlore latt…
Gravitomagnetism and Pulsar Beam Precession near a Kerr Black Hole
Prashant Kocherlakota, Pankaj S. Joshi, Sudip Bhattacharyya +3
A rotating black hole causes the spin-axis of a nearby pulsar to precess due to geodetic and gravitomagnetic frame-dragging effects. The aim of our theoretical work here is to expl…
Semiclassical theory for liquid-like behaviour of the frustrated magnet
Sounak Biswas, Kedar Damle
We identify the low energy effective Hamiltonian that is expected to describe the low temperature properties of the frustrated magnet $\mathrm{Ca}_{10}\mathrm{Cr}_{7}\mathrm{O}_{28…
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…

Sounak Biswas, Geet Rakala, Kedar Damle
Working within the stochastic series expansion framework, we introduce and characterize a new quantum cluster algorithm for quantum Monte Carlo simulations of transverse field Isin…
