Entanglement theory with limited computational resources
We now aim to determine the fundamental limits and possibilities of computationally efficient entanglement manipulation. Here the goal…
Inadequacy of the Casimir force for explaining a strong attractive force in a micrometre-sized narrow-gap re-entrant cavity
Pate, J., Goryachev, M., Chiao, R., Sharping, J. & Tobar, M. Casimir spring and dilution in macroscopic cavity…
6 Times Einstein Missed the Mark, but Still Changed Physics
Albert Einstein is undeniably one of the greatest names in physics. But Einstein, for all his contributions to…
Researchers Claim First ‘Unconditional Proof’ of Quantum Advantage. What Happens Next?
Quantum computers are already here, even though it’s not readily apparent. Now, researchers say quantum advantage—the field’s long-promised…
Entanglement and the density matrix renormalization group in the generalized Landau paradigm
Dualities We explain here how to obtain the models dual to equation (1) considered in the main text.…
Exact collective occupancies of the Moshinsky model in two-dimensional geometry
We consider a system of N bosons in a two-dimensional isotropic harmonic potential, interacting with a force proportional…
Twist on Famous Double-Slit Experiment Deals a Blow to Einstein’s Quantum Doubts
Albert Einstein famously disliked quantum theory’s understanding that physical objects, including light, exist as both a particle and…
After 100 Years of Quantum Mechanics, Physicists Still Can’t Agree on Anything
In July 1925—exactly a century ago—famed physicist Werner Heisenberg wrote a letter to his equally famous colleague, Wolfgang…
Microscopic theory of polariton group velocity renormalization
Model system We use the Generalized Holstein-Tavis-Cummings (GHTC) Hamiltonian23,24,25,26 to describe N excitons interacting with \({{{\mathcal{M}}}}\) cavity modes,…
Radical New Theory Rewrites the Story of the Earliest Universe
Following the Big Bang, our universe expanded at an exponential rate. According to this theory, known as cosmic…
