Variationally Optimized Imaginary-time Polynomial Filters for Ground State Projection
Bahman Seifi, Ibsal Assi, J. P. F. LeBlanc
In this work, we develop a variational imaginary-time evolution (ITE) framework based on polynomial filtering, derived from an operator-level action principle, which yields an opti…
A Variational Framework for Time-Dependent Quantum Systems with Applications to Floquet Hamiltonians
Ibsal Assi, Meenu Kumari, J. P. F. LeBlanc
We introduce a variational framework for approximating the time-evolution operator within a physically motivated operator manifold, reformulating quantum dynamics as a…
Beyond Trotterization: Variational Product Formulas for Quantum Simulation
Ibsal Assi, Michael Vogl, Meenu Kumari +1
We propose a variational alternative to the Trotter-Suzuki decomposition that provides greater control over errors while preserving the unitary structure of time evolution. The var…
NonHermitian Topological Phases in a Hermitian Modified Bosonic Kitaev Chain
Raditya Weda Bomantara, Ibsal Assi, J. P. F. LeBlanc +1
We present a modification to the bosonic Kitaev chain that, despite being Hermitian, supports both nonHermitian skin effect and nontrivial topological edge modes in its excitation…
Designing Majorana Quasiparticles in InAsP Quantum Dots in InP Nanowires with Variational Quantum Eigenvalue Solver
Mahan Mohseni, Iann Cunha, Daniel Miravet +5
This work presents steps toward the design of Majorana zero modes (MZM) in InAsP quantum dots (QD) embedded in an InP semiconducting nanowire in contact with a p-type superconducto…
Bound-states for generalized trigonometric and hyperbolic Pöschl-Teller potentials
A. D. Alhaidari, I. A. Assi, A. Mebirouk
We use the "tridiagonal representation approach" to solve the time-independent Schrödinger equation for the bound states of generalized versions of the trigonometric and hyperbolic…
