We derive the full linear-response theory for nonrelativistic quantum electrodynamics in the long wavelength limit and provide a practical framework to solve the resulting equations by using ...

GPT is a Python measurement toolkit built on Grid data parallelism (MPI, OpenMP, SIMD, and SIMT). It provides a physics library for lattice QCD and related theories, a QIS module including a digital ...

In the present study, several mixed quantum-classical (MQC) methods are applied to on-the-fly nonadiabatic molecular dynamics simulations of hole transport in molecular organic semiconductors (OSCs).

A new study shows quantum entanglement follows universal rules across dimensions using thermal effective theory.

Classical simulations of quantum computations are vital for the future development of this emerging technology. To this end, decision diagrams have been proposed as a complementary technique which ...

The classical simulation of quantum circuits is essential in the development and testing of quantum algorithms. Methods based on tensor networks or decision diagrams have proven to alleviate the ...

When mathematicians revived ignored mathematical structures, they found that overlooked particles, called "neglectons," could complete the quantum computing puzzle.

String theory—the idea that particles are not point-like, but instead one-dimensional strings—is a popular theoretical framework that attempts to combine general relativity and quantum field ...

These quasiparticles, first introduced in high-energy physics and quantum field theory, have since attracted intense interest in condensed matter physics and photonics, owing to their potential as ...

The same has been true of loop quantum gravity, an even more radical approach that replaces the fabric of space-time (not just the elementary particles that live in it) with tiny loops.
