$$H=\mathop{\sum }\limits_{pq=1}^{N}{h}_{pq}{a}_{p}^{\dagger }{a}_{q}+\frac{1}{2}\mathop{\sum }\limits_{pqrs=1}^{N}{h}_{pqrs}{a}_{p}^{\dagger }{a}_{q}^{\dagger }{a ...
Researchers at Freie Universität Berlin, University of Maryland and NIST, Google AI, and Abu Dhabi set out to robustly estimate the free Hamiltonian parameters of bosonic excitations in a ...
A fast and adaptable method for high accuracy integration of the time-dependent Schrödinger equation
We present an adaptable, fast, and robust method for integrating the time-dependent Schrödinger equation. We apply the method to calculations of High Harmonic (HHG) and Above Threshold Ionisation (ATI ...
Hermitian Hamiltonians are a fundamental concept in quantum mechanics, serving as the mathematical foundation for describing the energy and time evolution of quantum systems. They are named after the ...
