Experimental quantum state learning with pairs of photons
C. Pria Dobney, Johan Henaff, Allen Kasum +5
Tomography allows one to estimate the density matrix describing the state an ensemble of quantum systems are prepared in (for example, polarization tomography determines the polari…
Thomas-Fermi equation revisited: A variation on a theme by Majorana
Berthold-Georg Englert
Majorana found a way to exploit the scaling properties of the Thomas-Fermi equation for converting this second-order differential equation into one of first order. We explore his m…
State learning from pairs of states
Pranjal Agarwal, Nada Ali, Camilla Polvara +3
Suppose you receive a sequence of qubits where each qubit is guaranteed to be in one of two pure states, but you do not know what those states are. Your task is to determine the st…
Uncertainty relations revisited
Berthold-Georg Englert
Introductory courses on quantum mechanics usually include lectures on uncertainty relations, typically the inequality derived by Robertson and, perhaps, other statements. For the b…
Single-particle-exact density functional theory
Martin-Isbjörn Trappe, Jun Hao Hue, Jonah Huang Zi Chao +4
We introduce 'single-particle-exact density functional theory' (1pEx-DFT), a novel density functional approach that represents all single-particle contributions to the energy with…
Contactium: A strongly correlated model system
Jerzy Cioslowski, Berthold-Georg Englert, Martin-Isbjörn Trappe +1
At the limit of an infinite confinement strength , the ground state of a system that comprises two fermions or bosons in a harmonic confinement interacting through the Fermi--Hu…
