Ansätz Expressivity and Optimization in Variational Quantum Simulations of Transverse-field Ising Model Across System Sizes
Ashutosh P. Tripathi, Nilmani Mathur, Vikram Tripathi
We explore the application of the Variational Quantum Eigensolver (VQE) to investigate the ground state properties, particularly the entanglement entropy, of the Transverse Field I…
Optimization of the HHL Algorithm
Dhruv Sood, Nilmani Mathur, Vikram Tripathi
The Harrow-Hassidim-Lloyd (HHL) algorithm is a quantum algorithm for solving systems of linear equations that, in principle, offers an exponential improvement in scaling with the s…
Hidden subspace symmetry protection for quantum scars
Ayush Sharma, Vikram Tripathi
We study the paradigmatic spin-1 XY chain under open boundary conditions, which hosts exact quantum many-body scars generated by an emergent Spectrum Generating Algebra (SGA). We s…
Web of Non-invertible Dualities for (2+1) Dimensional Models with Subsystem Symmetries
Avijit Maity, Vikram Tripathi, Andriy H. Nevidomskyy
We extend non-invertible duality concepts from one-dimensional systems to two spatial dimensions by constructing a web of non-invertible dualities for lattice models with subsystem…
Identifying chiral topological order in microscopic spin models by modular commutator
Avijit Maity, Aman Kumar, Vikram Tripathi
The chiral central charge is a key topological invariant of the edge characterizing the bulk two-dimensional chiral topological order, but its direct evaluation in microscopi…
Thermal Hall response of an abelian chiral spin liquid at finite temperatures
Avijit Maity, Haoyu Guo, Subir Sachdev +1
Thermal Hall transport has emerged as a valuable tool for probing the fractionalized excitations in chiral quantum spin liquids. Observing quantized thermal Hall response, expected…
Robustness of a state with Ising topological order against local projective measurements
Sanjeev Kumar, Vikram Tripathi
We investigate the fragility of a topologically ordered state, namely, the ground state of a weakly Zeeman perturbed honeycomb Kitaev model to environment induced decoherence effec…
Field tuning Kitaev systems for spin fractionalization and topological order
Jagannath Das, Sarbajaya Kundu, Aman Kumar +1
The honeycomb Kitaev model describes a spin liquid with topological order and fractionalized excitations consisting of gapped -fluxes and free Majorana fermions. Competing…
Microscopic theory of field-tuned topological transitions in the Kitaev honeycomb model
Jagannath Das, Aman Kumar, Vikram Tripathi
We microscopically construct an abelian mutual Chern-Simons lattice gauge theory for magnetic field-tuned topological transitions in the Kitaev model and obtain a complete characte…
Competing phases and critical behavior in three coupled spinless Luttinger liquids
S. Kundu, V. Tripathi
We study electronic phase competition in a system of three coupled spinless Luttinger liquids using abelian bosonization, together with a perturbative renormalization group (RG) an…
Quantum Criticality in the 122 Iron Pnictide Superconductors Emerging from Orbital-Selective Mottness
S. D. Das, M. S. Laad, L. Craco +3
The twin issues of the nature of the normal state and competing order(s) in the iron arsenides are central to understanding their unconventional, high-Tc superconductivity. We use…
