Quantum complexity across thermal phase transition in the transverse field Ising chain with long-range couplings
Meghadeepa Adhikary, Nishan Ranabhat, Mario Collura
We investigate the behavior of the Schmidt gap, the von Neumann entanglement entropy, and the non-stabiliserness in proximity to the classical phase transition of the one-dimension…
Classical fracton spin liquid and Hilbert space fragmentation in a 2D spin- model
Nils Niggemann, Meghadeepa Adhikary, Yannik Schaden-Thillmann +1
Classical U(1) fracton spin liquids feature an extensive ground state degeneracy and follow an effective description in terms of a tensor Gauss' law where charges, so-called fracto…
Gapless fracton quantum spin liquid and emergent photons in a 2D spin-1 model
Nils Niggemann, Meghadeepa Adhikary, Yannik Schaden-Thillmann +1
Gapless fracton quantum spin liquids are exotic phases of matter described by higher-rank U(1) gauge theories which host gapped and immobile fracton matter excitations as well as g…
Quantum paramagnetism and magnetization plateaus in a kagome-honeycomb Heisenberg antiferromagnet
Meghadeepa Adhikary, Arnaud Ralko, Brijesh Kumar
A spin-1/2 Heisenberg model on honeycomb lattice is investigated by doing triplon analysis and quantum Monte Carlo calculations. This model, inspired by Cu(pymca)(ClO),…
