Flat-band physics in the spin-1/2 sawtooth chain [PDF]
European Physical Journal B : Condensed Matter Physics, 2020 We consider the strongly anisotropic spin-1/2 XXZ model on the sawtooth-chain lattice with ferromagnetic longitudinal interaction J zz = Δ J and aniferromagnetic transversal interaction J xx = J yy = J > 0.

Echoes of compact objects: New physics near the surface and matter at a distance [PDF]
Physical Review D, 2018 It is well known that a hypothetical compact object that looks like an Einsteinian (Schwarzschild or Kerr) black hole everywhere except a small region near its surface should have the ringdown profile predicted by the Einstein theory at early and ...

Screening nature of the van der Waals density functional method: a review and analysis of the many-body physics foundation [PDF]
Journal of Physics: Condensed Matter, 2019 We review the screening nature and many-body physics foundation of the van der Waals density functional (vdW-DF) method [Berland K et al 2015 Rep. Prog. Phys.

European Physical Journal C: Particles and Fields, 2019 This paper is an addendum to Ref. Eur. Phys. J. C79 (2019) no. 8, 714 that supersedes all results (Tables and Figures) in that paper after including the new data on the $$B\rightarrow K^*\mu \mu $$ B → K ∗ μ μ angular distribution released in 2020 by the

Physics-based modeling and data representation of pairwise interactions among pedestrians [PDF]
Physical Review E, 2018 In this work we study pedestrian-pedestrian interactions from observational experimental data in diluted pedestrian crowds. While in motion, pedestrians continuously adapt their walking paths trying to preserve mutual comfort distances and to avoid ...

Efimov Physics in Quenched Unitary Bose Gases. [PDF]
Physical Review Letters, 2018 We study the impact of three-body physics in quenched unitary Bose gases, focusing on the role of the Efimov effect. Using a local density model, we solve the three-body problem and determine three-body decay rates at unitarity, finding density-dependent,

Quantum-optical tests of Planck-scale physics [PDF]
Physical Review A, 2017 Recently it was proposed to use cavity-optomechanical systems to test for quantum gravity corrections to quantum canonical commutation relations [Nat. Phys. 8, 393-397 (2012)].

B→πll Form Factors for New Physics Searches from Lattice QCD. [PDF]
Physical Review Letters, 2015 The rare decay B→πℓ^{+}ℓ^{-} arises from b→d flavor-changing neutral currents and could be sensitive to physics beyond the standard model. Here, we present the first ab initio QCD calculation of the B→π tensor form factor f_{T}.
