Andreev–Bashkin effect in superfluid cold gases mixtures

Autor: Jacopo Nespolo, Grigori E Astrakharchik, Alessio Recati

Publikováno v: New Journal of Physics, Vol 19, Iss 12, p 125005 (2017)

We study a mixture of two superfluids with density–density and current–current (Andreev–Bashkin) interspecies interactions. The Andreev–Bashkin coupling gives rise to a dissipationless drag (or entrainment) between the two superfluids. Within

Spin- and density-resolved microscopy of antiferromagnetic correlations in Fermi-Hubbard chains

Autor: Guillaume Salomon, Jacopo Nespolo, Immanuel Bloch, Martin Boll, Lode Pollet, Ahmed Omran, Christian Gross, Timon A. Hilker

Publikováno v: Science

The repulsive Hubbard Hamiltonian is one of the foundational models describing strongly correlated electrons and is believed to capture essential aspects of high-temperature superconductivity. Ultracold fermions in optical lattices allow for the simu

The interplay between magnetism and doping is at the origin of exotic strongly correlated electronic phases and can lead to novel forms of magnetic ordering. One example is the emergence of incommensurate spin-density waves, which have wavevectors th

Author Correction: Direct observation of incommensurate magnetism in Hubbard chains

Autor: Immanuel Bloch, Jacopo Nespolo, Joannis Koepsell, Jayadev Vijayan, Christian Gross, Lode Pollet, Timon A. Hilker, Guillaume Salomon

Publikováno v: Nature. 566:E5-E5

In this Letter, the affiliation for Christian Gross should have been 'Max-Planck-Institut für Quantenoptik, Garching, Germany' instead of 'Fakultät für Physik, Ludwig-Maximilians-Universität, Munich, Germany'; this has been corrected online.

Phase diagram and multicritical behaviors of mixtures of three-dimensional bosonic gases

Autor: Giacomo Ceccarelli, Jacopo Nespolo, Ettore Vicari, Andrea Pelissetto

We investigate the Bose-Einstein condensation (BEC) patterns, the critical and multicritical behaviors of three-dimensional mixtures of bosonic gases with density-density interactions, characterized by a global U(1)circle plus U(1) symmetry [one U(1)

Bose-Einstein condensation and critical behavior of two-component bosonic gases

Autor: Ettore Vicari, Giacomo Ceccarelli, Jacopo Nespolo, Andrea Pelissetto

We study Bose-Einstein condensation (BEC) in three-dimensional two-component bosonic gases, characterizing the universal behaviors of the critical modes arising at the BEC transitions. For this purpose, we use field-theoretical (FT) renormalization-g

Finite-size scaling at the first-order quantum transitions of quantum Potts chains

Autor: Jacopo Nespolo, Andrea Pelissetto, Ettore Vicari, Massimo Campostrini

We investigate finite-size effects in quantum systems at first-order quantum transitions. For this purpose we consider the one-dimensional q-state Potts models which undergo a first-order quantum transition for any q>4, separating the quantum disorde

Finite-size scaling at first-order quantum transitions

Autor: Jacopo Nespolo, Ettore Vicari, Massimo Campostrini, Andrea Pelissetto

We study finite-size effects at first-order quantum transitions (FOQTs). We show that the low-energy properties show a finite-size scaling (FSS) behavior, the relevant scaling variable being the ratio of the energy associated with the perturbation dr

Scaling phenomena driven by inhomogeneous conditions at first-order quantum transitions

Autor: Jacopo Nespolo, Andrea Pelissetto, Ettore Vicari, Massimo Campostrini

We investigate the effects of smooth inhomogeneities at first-order quantum transitions (FOQT), such as those arising from the presence of a space-dependent external field, which smooths out the typical discontinuities of the low-energy properties. W
