Hydrogenic Spin-Valley states of the Bromine donor in 2H-MoTe
Valeria Sheina, Guillaume Lang, Vasily Stolyarov +14
In semiconductors, the identification of doping atomic elements allowing to encode a qubit within spin states is of intense interest for quantum technologies. In transition metal d…
Love--Lieb integral equations: applications, theory, approximations, and computation
Leandro Farina, Guillaume Lang, P. A. Martin
This paper is concerned mainly with the deceptively simple integral equation \[ u(x) - \frac{1}π\int_{-1}^{1} \frac{α\, u(y)}{α^2+(x-y)^2} \, \rd y = 1, \quad -1 \leq x \leq 1, \]…
Conjectures about the structure of strong- and weak-coupling expansions of a few ground-state observables in the Lieb-Liniger and Yang-Gaudin models
Guillaume Lang
In this paper, we apply experimental number theory to two integrable quantum models in one dimension, the Lieb-Liniger Bose gas and the Yang-Gaudin Fermi gas with contact interacti…
Correlations in low-dimensional quantum gases
Guillaume Lang
Ultracold gases are a versatile platform to simulate condensed matter physics, as virtually any parameter is experimentally tunable. In particular, highly anisotropic traps allow t…
A connection between non-local one-body and local three-body correlations of the Lieb-Liniger model
Maxim Olshanii, Vanja Dunjko, Anna Minguzzi +1
We derive a connection between the fourth coefficient of the short-distance Taylor expansion of the one-body correlation function, and the local three-body correlation function of…
Tan's contact of a harmonically trapped one-dimensional Bose gas: strong-coupling expansion and conjectural approach at arbitrary interactions
Guillaume Lang, Patrizia Vignolo, Anna Minguzzi
We study Tan's contact, i.e. the coefficient of the high-momentum tails of the momentum distribution at leading order, for an interacting one-dimensional Bose gas subjected to a ha…
