Unifying gravity and quantum theory requires better understanding of time
Quantum mechanics is our most successful physical theory. Created to account for atomic phenomena, it has a vast…
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…

Fifty-six years after Disney filmmakers imagined what it would be like for a spacecraft crew to journey to…
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…
