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…

Majorana Fermions in spin up and down electronic complexes in spin-orbit coupled array of semiconductor quantum dots in proximity to -type superconductor and in magnetic field

Mijanur Islam, Mahan Mohseni, Ibsal Assi +2

Semiconductor-s-type superconductor nanowires host spinful fermions and cannot be reduced to a single spinless Kitaev chain hosting single Majorana zero mode. Instead, such systems…

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…
