From Quantum Dimers to the -flux Toric Code via Deconfined Multicriticality
Ankush Chaubey, Sergej Moroz, Subhro Bhattacharjee
Two-dimensional Rokhsar-Kivelson (RK) dimer models on bipartite lattices are generally limited to translation-symmetry-broken dimer crystals. We introduce a tensor-product regulari…
Arrested Relaxation in a Disorder-Free Coulomb Spin Liquid
Souvik Kundu, Arnab Seth, Sthitadhi Roy +2
We investigate Coulomb spin liquids in classical spin-3/2 ice and show that the enlarged on-site Hilbert space gives rise to a qualitatively new class of such phases. Beyond the co…
How many-body chaos emerges in the presence of quasiparticles
Sibaram Ruidas, Sthitadhi Roy, Subhro Bhattacharjee +1
Many-body chaos is a default property of many-body systems; at the same time, near-integrable behaviour due to weakly interacting quasiparticles is ubiquitous throughout condensed…
Stress Response of Jammed Solids: Prestress and Screening
Surajit Chakraborty, Jishnu N. Nampoothiri, Subhro Bhattacharjee +2
Unlike classical elasticity, where stresses arise from deformations relative to a stress-free reference configuration, rigidity in amorphous systems is maintained by disordered for…
Multiple Dirac Spin-Orbital Liquids in SU(4) Heisenberg Antiferromagnets on the Honeycomb Lattice
Manoj Gupta, Arijit Haldar, Subhro Bhattacharjee +1
We study the strong coupling model of transition metal tri-halides in the large spin-orbit coupled limit. By considering ab-initio-calculation-inspired hierarchy of hopping p…
Intermittent fluctuations determine the nature of chaos in turbulence
Aikya Banerjee, Ritwik Mukherjee, Sugan Durai Murugan +2
We adapt recent ideas for many-body chaos in nonlinear, Hamiltonian fluids [Murugan \textit{et al.}, Phys. Rev. Lett. 127, 124501 (2021)] to revisit the question of the Reynolds nu…
