Anyon Quasilocalization in a Quasicrystalline Toric Code
Soumya Sur, Mohammad Saad, Adhip Agarwala
An exactly solvable model of a quantum spin liquid on a quasicrystal, akin to Kitaev's honeycomb model, was introduced in Kim \textit{et al.}, \href{https://doi.org/10.1103/PhysRev…
Signatures of emergent surface states across a displacive topological phase transition in BiI
Deep Singha Roy, Sk Kalimuddin, Subrata Pachhal +13
Topological phase transitions involving crystalline symmetry breaking provide a fertile ground to explore the interplay between symmetry, topology, and emergent quantum phenomena.…
Tunable anyonic permeability across spin liquid junctions
Sayak Bhattacharjee, Soumya Sur, Adhip Agarwala
We introduce two classes of junctions in a toric code, a prototypical model of a quantum spin liquid, and study the nature of anyonic transport across them mediated…
Quasicrystalline Spin Liquid
Sunghoon Kim, Mohammad Saad, Dan Mao +2
The interplay of electronic interactions and frustration in crystalline systems leads to a panoply of correlated phases, including exotic Mott insulators with non-trivial patterns…
Signatures of quantum phases in a dissipative system
Rohan Joshi, Saikat Mondal, Souvik Bandyopadhyay +2
Lindbladian formalism, as tuned to dissipative and open systems, has been all-pervasive to interpret non-equilibrium steady states of quantum many-body systems. We study the fate o…
Symmetry-Enriched Criticality in a Coupled Spin-Ladder
Suman Mondal, Adhip Agarwala, Tapan Mishra +1
We study a one-dimensional ladder of two coupled XXZ spin chains and identify several distinct gapless symmetry-enriched critical phases. These have the same unbroken symmetries an…
Dimensional reduction of Kitaev spin liquid at quantum criticality
Shi Feng, Adhip Agarwala, Nandini Trivedi
We investigate the fate of the Kitaev spin liquid (KSL) under the influence of an external magnetic field in the [001] direction and upon tuning bond anisotropy of the Kitaev c…
Correlation-driven non-trivial phases in single bi-layer Kagome intermetallics
Aabhaas Vineet Mallik, Adhip Agarwala, Tanusri Saha-Dasgupta
Bi-layer Kagome compounds provide an exciting playground where the interplay of topology and strong correlations can give rise to exotic phases of matter. Motivated by recent first…
Spectral Form Factors of Topological Phases
Anurag Sarkar, Subrata Pachhal, Adhip Agarwala +1
Signatures of dynamical quantum phase transitions and chaos can be found in the time evolution of generalized partition functions such as spectral form factors (SFF) and Loschmidt…
Anyon dynamics in field-driven phases of the anisotropic Kitaev model
Shi Feng, Adhip Agarwala, Subhro Bhattacharjee +1
The Kitaev model on a honeycomb lattice with bond-dependent Ising interactions offers an exactly solvable model of a quantum spin liquid (QSL) with gapped fluxes and gapless…
Fractionalization and topology in amorphous electronic solids
Sunghoon Kim, Adhip Agarwala, Debanjan Chowdhury
Band-topology is traditionally analyzed in terms of gauge-invariant observables associated with crystalline Bloch wavefunctions. Recent work has demonstrated that many of the free…
Phases and Quantum Phase Transitions in Anisotropic Antiferromagnetic Kitaev-Heisenberg- magnet
Animesh Nanda, Adhip Agarwala, Subhro Bhattacharjee
We study the Kitaev-Heisenberg- model with antiferromagnetic Kitaev exchanges in the strong anisotropic (toric code) limit to understand the phases and the intervening phase tra…
Statistics tuned entanglement of the boundary modes in coupled Su-Schrieffer-Heeger chains
Saikat Santra, Adhip Agarwala, Subhro Bhattacharjee
We show that mutual statistics between quantum particles can be tuned to generate emergent novel few particle quantum mechanics for the boundary modes of symmetry-protected topolog…
Gapless state of interacting Majorana fermions in a strain-induced Landau level
Adhip Agarwala, Subhro Bhattacharjee, Johannes Knolle +1
Mechanical strain can generate a pseudo-magnetic field, and hence Landau levels (LL), for low energy excitations of quantum matter in two dimensions. We study the collective state…
Statistics-tuned phases of pseudofermions in one dimension
Adhip Agarwala, Gaurav Kumar Gupta, Vijay B. Shenoy +1
We show that a quadratic system of pseudofermions, with tunable fractionalised statistics, can host a rich phase diagram on a one dimensional chain with nearest and next nearest ne…
