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 (MF) phase; a massive fermion phase with spontaneous symmetry breaki…
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…
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…
