Ferromagnetic transition in a chiral spin chain
Yuan Xiao, Rimika Jaiswal, Oleg A. Starykh +1
We study the zero-temperature properties of a spin- Heisenberg chain with an additional three-site chiral term of strength . The model is known to be integrable and previou…
Agents' Last Exam
Yiyou Sun, Xinyang Han, Weichen Zhang +378
Recent AI systems have achieved strong results on a wide range of benchmarks, yet these gains have not translated into economically meaningful deployment across many professional d…
MoSAIC: Scalable Probabilistic Error Cancellation via Variational Blockwise Noise Aggregation
Maya Ma, Rimika Jaiswal, Murphy Yuezhen Niu
Quantum error mitigation is essential for extracting trustworthy results from noisy intermediate-scale quantum (NISQ) processors. Yet, current approaches face a core scalability bo…
Simulating a quasiparticle on a quantum device
Rimika Jaiswal, Izabella Lovas, Leon Balents
We propose a variational approach to explore quasiparticle excitations in interacting quantum many-body systems, motivated by the potential in leveraging near-term noisy intermedia…
Stabilizing topological superconductivity in disordered spin-orbit coupled semiconductor-superconductor heterostructures
Binayyak B. Roy, Rimika Jaiswal, Tudor D. Stanescu +1
We investigate theoretically a one-dimensional semiconductor-superconductor (SM-SC) heterostructure with Rashba spin-orbit coupling and parallel Zeeman field in the presence of dis…
Scalable Quantum Ground State Preparation of the Heisenberg Model: A Variational Quantum Eigensolver Approach
Jinao Wang, Rimika Jaiswal
Quantum systems have historically been formidable to simulate using classical computational methods, particularly as the system size grows. In recent years, advancements in quantum…
A Tropical Geometric Approach To Exceptional Points
Ayan Banerjee, Rimika Jaiswal, Madhusudan Manjunath +1
Non-Hermitian systems have been widely explored in platforms ranging from photonics to electric circuits. A defining feature of non-Hermitian systems is exceptional points (EPs), w…
Characterizing and Tuning Exceptional Points Using Newton Polygons
Rimika Jaiswal, Ayan Banerjee, Awadhesh Narayan
The study of non-Hermitian degeneracies -- called exceptional points -- has become an exciting frontier at the crossroads of optics, photonics, acoustics, and quantum physics. Here…
Floquet Engineering of Multifold Fermions
Rimika Jaiswal, Awadhesh Narayan
Using Floquet theory, we investigate the effect of light on triple fold fermions. We study a low energy model as well as a simplified tight binding model under illumination. We fin…
