Physical properties of an aperiodic monotile with graphene-like features, chirality, and zero modes

J Schirmann, S Franca, F Flicker, AG Grushin - Physical Review Letters, 2024 - APS
The discovery of the Hat, an aperiodic monotile, has revealed novel mathematical aspects of
aperiodic tilings. However, the physics of particles propagating in such a setting remains …

Nematic superconductivity and its critical vestigial phases in the quasicrystal

YB Liu, J Zhou, F Yang - Physical Review Letters, 2024 - APS
We propose a general mechanism to realize nematic superconductivity (SC) and reveal its
exotic vestigial phases in the quasicrystal (QC). Starting from a Penrose-Hubbard model, our …

Hamiltonian cycles on ammann-beenker tilings

S Singh, J Lloyd, F Flicker - Physical Review X, 2024 - APS
We provide a simple algorithm for constructing Hamiltonian graph cycles (visiting every
vertex exactly once) on a set of arbitrarily large finite subgraphs of aperiodic two …

Statistical mechanics of dimers on quasiperiodic Ammann-Beenker tilings

J Lloyd, S Biswas, SH Simon, SA Parameswaran… - Physical Review B, 2022 - APS
We study classical dimers on two-dimensional quasiperiodic Ammann-Beenker (AB) tilings.
Using the discrete scale-symmetry of quasiperiodic tilings, we prove that each infinite tiling …

Emergent moments and random singlet physics in a Majorana spin liquid

S Sanyal, K Damle, JT Chalker, R Moessner - Physical Review Letters, 2021 - APS
We exhibit an exactly solvable example of a SU (2) symmetric Majorana spin liquid phase, in
which quenched disorder leads to random-singlet phenomenology of emergent magnetic …

Infinite randomness with continuously varying critical exponents in the random XYZ spin chain

B Roberts, OI Motrunich - Physical Review B, 2021 - APS
We study the antiferromagnetic XYZ spin chain with quenched bond randomness, focusing
on a critical line between localized Ising magnetic phases. A previous calculation using the …

Theory of collective topologically protected Majorana fermion excitations of networks of localized Majorana modes

K Damle - Physical Review B, 2022 - APS
Predictions of localized Majorana modes, and ideas for manipulating these degrees of
freedom, are the two key ingredients in proposals for physical platforms for Majorana …

Multiscale Excitations in the Diluted Two-dimensional S= 1/2 Heisenberg Antiferromagnet

L Dao, H Shao, AW Sandvik - arxiv preprint arxiv:2408.06749, 2024 - arxiv.org
We study the excitation spectrum of the $ S= 1/2$ Heisenberg model on the randomly
diluted square lattice by analytic continuation of QMC data. At dilution fractions $ p= 1/16 …

MZ Ansari, K Damle - Physical Review Letters, 2024 - APS
We study the effect of a small density nv of quenched nonmagnetic impurities, ie, vacancy
disorder, in gapped short-range resonating valence bond (RVB) spin liquid states and …

Gallai-Edmonds percolation of topologically protected collective Majorana excitations

R Bhola, K Damle - arxiv preprint arxiv:2311.05634, 2023 - arxiv.org
Majorana networks, whose vertices represent localized Majorana modes and edges
correspond to bilinear mixing amplitudes between them, provide a unified framework for …
