Majumdar 3 Gregory Schehr 3, * Journal of Statistical Mechanics: Theory and Experiment, IOP Science, 2017, 2017 (6), pp.063301 (1-39). 〈10.1088/1742-5468/aa6dda〉 We consider N non-interacting fermions in an isotropic d-dimensional harmonic trap. We compute analytically the cumulative distribution of the maximal radial distance of the

Bertrand Lacroix-A-Chez-Toine 1 Pierre Le Doussal 2 Satya Majumdar 1 Grégory Schehr 1 EPL, 2017, 120 (1), pp.10006. 〈10.1209/0295-5075/120/10006〉 We study N noninteracting fermions in a domain bounded by a hard-wall potential in dimensions. We show that for large N, the correlations at the edge of the Fermi gas (near the wall) at zero temperature

Bertrand Lacroix-A-Chez-Toine 1 Pierre Le Doussal 2 Satya N. Majumdar 1 Gregory Schehr 1 EPL – Europhysics Letters, European Physical Society/EDP Sciences/Società Italiana di Fisica/IOP Publishing, 2017 We study $N$ noninteracting fermions in a domain bounded by a hard wall potential in $d \geq 1$ dimensions. We show that for large $N$, the correlations at

J. Brox 1 P. Kiefer 1 M. Bujak 1 H. Landa 2 T. Schaetz 1 Physical Review Letters, American Physical Society, 2017, 119 (15), 〈10.1103/PhysRevLett.119.153602〉 We study experimentally and theoretically discrete solitons in crystalline structures consisting of several tens of laser-cooled ions confined in a radiofrequency trap. Resonantly exciting localized, spectrally gapped vibrational modes of

Kolton 3 Alberto Rosso 4 Physical Review Letters, American Physical Society, 2017, 118 (14), pp.147208 In presence of impurities, ferromagnetic and ferroelectric domain walls slide only above a finite external field. Close to this depinning threshold, they proceed by large and abrupt jumps,

S. K. Ivanov 1, 2 A. M. Kamchatnov 3, 1 T. Congy 4 N. Pavloff 4 Physical Review E , American Physical Society (APS), 2017, 96 (6), 〈10.1103/PhysRevE.96.062202〉 We provide a classification of the possible flow of two-component Bose-Einstein condensates evolving from initially discontinuous profiles. We consider the situation where the dynamics can be reduced

Thierry Jolicoeur 1 Physical Review B : Condensed matter and materials physics, American Physical Society, 2017, 95, pp.075201 We revisit the theory of the collective neutral excitation mode in the fractional quantum Hall effect at Landau level filling fractions $\nu=1/3$ and $\nu=7/3$. We include the effect of finite thickness of the two-dimensional electron gas and

Vladimir Belavin 1, 2 Xiangyu Cao 3 Benoit Estienne 4 Raoul Santachiara 3 Journal of High Energy Physics, Springer, 2017, 3, pp.008 In a recent study we considered W3 Toda 4-point functions that involve matrix elements of a primary field with the highest-weight in the adjoint representation of sl3. We generalize this result by considering

This long-standing question belongs to the extensively studied class of explore/exploit problems that arise in a wide range of situations, from animal foraging, to robotic exploration,
