Investigating Interacting Fermionic Models with Locality-Preserving Qubit Encodings
Ashutosh P. Tripathi, Debasish Banerjee, Sandip Maiti +1
We investigate the utility of the locality-preserving Derby-Klassen (DK) fermion-to-qubit mapping [arXiv:2003.06939] for variational quantum simulation of two-dimensional - a…
Frustration-Induced Expressibility Limitations in Variational Quantum Algorithms
Sandip Maiti
Geometric frustration, arising from competing interactions that prevent simultaneous energy minimization, presents a fundamental challenge for variational quantum algorithms applie…
Symmetric Mass Generation via Multicriticality in a 3D Lattice Gross-Neveu Model
Sandip Maiti, Debasish Banerjee, Shailesh Chandrasekharan +1
We investigate a three-dimensional lattice model of two flavors of massless staggered fermions coupled through two independent four-fermion interactions, and . Using lar…
Phase diagram of a lattice fermion model with symmetric mass generation
Sandip Maiti, Debasish Banerjee, Shailesh Chandrasekharan +1
We study the phase structure of a model containing two flavors of massless staggered fermions interacting through two independent four-fermion couplings, UI and UB, formulated on a…
Symmetric Mass Generation as a Multicritical Point with Enhanced Symmetry
Sandip Maiti, Debasish Banerjee, Shailesh Chandrasekharan +1
We explore the phase diagram of a lattice fermion model that exhibits three distinct phases: a massless fermion phase, a massive fermion phase with spontaneous symmetry breaking in…
Towards the phase diagram of fermions coupled with quantum links in -D
Graham Van Goffrier, Debasish Banerjee, Bipasha Chakraborty +2
Quantum link models (QLMs) are generalizations of Wilson's lattice gauge theory formulated with finite-dimensional link Hilbert spaces. In certain cases, the non-Abelian Gauss Law…
Spontaneous symmetry breaking in a non-Abelian lattice gauge theory in D with quantum algorithms
Sandip Maiti, Debasish Banerjee, Bipasha Chakraborty +1
The simulation of various properties of quantum field theories is rapidly becoming a testing ground for demonstrating the prowess of quantum algorithms. Some examples include the p…
A qubit regularization of asymptotic freedom without fine-tuning
Sandip Maiti, Debasish Banerjee, Shailesh Chandrasekharan +1
Other than the commonly used Wilson's regularization of quantum field theories (QFTs), there is a growing interest in regularizations that explore lattice models with a strictly fi…
Asymptotic Freedom at the Berezinskii-Kosterlitz-Thouless Transition without Fine-Tuning Using a Qubit Regularization
Sandip Maiti, Debasish Banerjee, Shailesh Chandrasekharan +1
We propose a two-dimensional hard-core loop-gas model as a way to regularize the asymptotically free massive continuum quantum field theory that emerges at the Berezinskii-Kosterli…
