Ansätz Expressivity and Optimization in Variational Quantum Simulations of Transverse-field Ising Model Across System Sizes
Ashutosh P. Tripathi, Nilmani Mathur, Vikram Tripathi
The paper studies how well the Variational Quantum Eigensolver can find ground‑state properties, especially entanglement entropy, of the transverse‑field Ising model in 1‑D, 2‑D, a…
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…
