“…Still more heavy nucleus 31 Ne, predicted to be one neutron-halo as per our model, found experimental confirmation in 2009 [14]. Still heavier nucleus 37 Mg, was found to be a one neutron halo nucleus in 2014 [15], one more confirmation of our model. All this provides clear and unambiguos support to our model.…”

In a decade-and-a-half old experiment, Raabe et al. (Nature 431 (2004) 823), had studied fusion of an incoming beam of halo nucleus 6 He with the target nucleus 238 U. We extract a new interpretation of the experiment, different from the one that has been inferred so far. We show that their experiment is actually able to discriminate between the structures of the target nucleus (behaving as standard nucleus with density distribution described with canonical RMS radius r = r 0 A 1 3 with r 0 = 1.2 fm), and the "core" of the halo nucleus, which surprisingly, does not follow the standard density distribution with the above RMS radius. In fact the core has the structure of a tennis-ball (bubble) like nucleus, with a "hole" at the centre of the density distribution. This novel interpretation of the fusion experiment provides an unambigous support to an almost two decades old model (Abbas, Mod. Phys. Lett. A 16 (2001) 755), of the halo nuclei. This Quantum Chromodyanamics based model, succeeds in identifyng all known halo nuclei and makes clear-cut and unique predictions for new and heavier halo nuclei. This model supports the existence of tennis-ball (bubble) like core, of even the giant-neutron halo nuclei. This should prove beneficial to the experimentalists, to go forward more confidently, in their study of exotic nuclei.

“…Finally, the observation of anisotropic responses gives experimental support for the existence of the quantum Hall stripe phase [15][16][17][18]. In addition, the anisotropy is an intrinsic property of many quasi-two-dimensional materials such as organic compounds, for example, Bechgaard salts, in which quantum Hall effect has been studied [19][20][21][22][23][24][25]. For the use of wire construction beyond quantum Hall effect we refer to Refs.…”

Helical nuclear spin order in a strip of stripes in the quantum Hall regime

et al. 2014

View full text Add to dashboard Cite

We investigate nuclear spin effects in a two-dimensional electron gas in the quantum Hall regime modeled by a weakly coupled array of interacting quantum wires. We show that the presence of hyperfine interaction between electron and nuclear spins in such wires can induce a phase transition, ordering electrons and nuclear spins into a helix in each wire. Electron-electron interaction effects, pronounced within the one-dimensional stripes, boost the transition temperature up to tens to hundreds of millikelvins in GaAs. We predict specific experimental signatures of the existence of nuclear spin order, for instance for the resistivity of the system at transitions between different quantum Hall plateaus.

“…On the other hand, in many cases, the LMA phenomena are experimentally claimed [9-13] to be of a nonFermi-liquid nature. This was claimed by Chaikin's group for the Nernst effect in (TMTSF) 2 PF 6 [9,10,12], by Brooks' group for the Nernst effect in (TMTSF) 2 ClO 4 [11], and recently by Uji's group [13] for the Hall effect in (TMTSF) 2 ClO 4 . In our opinion, some non-Fermi-liquid effects were also observed in the LMA resistive experiments in the Q1D compound (Per) 2 Au(mnt) 2 by Graf et al [14].…”

Non-Fermi-liquid magic angle effects in high magnetic fields

We investigate a theoretical problem of electron-electron interactions in an inclined magnetic field in a quasi-one-dimensional (Q1D) conductor. We show that they result in strong non-Fermi-liquid corrections to a specific heat, provided that the direction of the magnetic field is far from the so-called Lebed's magic angles (LMAs). If magnetic field is directed close to one of the LMAs, the specific heat corrections become small and the Fermi-liquid picture restores. As a result, we predict Fermi-liquid-non-Fermi-liquid angular crossovers in the vicinities of the LMA directions of the field. We suggest to perform the corresponding experiment in the Q1D conductor (Per) 2 Au(mnt) 2 under pressure in magnetic fields of the order of H 25 T. DOI: 10.1103/PhysRevB.94.035162 It is well known that closed electron orbits in a magnetic field in metals are characterized by de Haas-van Alphen and Shubnikov-de Haas quantum oscillations [1]. For open orbits, Landau quantization is not possible and another quantum effect-Bragg reflection from boundaries of the Brillouin zone-plays an important role [2][3][4]. In particular, it has been shown [5][6][7][8] that the latter effect results in the appearance of angular magnetic oscillations, such as the so-called Lebed's magic angles (LMAs), Danner-Kang-Chaikin's (DKC) oscillations, and Lee-Naughton-Lebed's (LNL) ones. It is important that the DKC and LNL oscillations are well explained within the Fermi-liquid approach to open quasi-one-dimensional (Q1D) pieces of the Fermi surface in the Q1D conductors (TMTSF) 2 X (X = ClO 4 , PF 6 , etc.), (DMET) 2 I 3 , and some others [4,[6][7][8]. On the other hand, in many cases, the LMA phenomena are experimentally claimed [9-13] to be of a nonFermi-liquid nature. This was claimed by Chaikin's group for the Nernst effect in (TMTSF) 2 PF 6 [9,10,12], by Brooks' group for the Nernst effect in (TMTSF) 2 ClO 4 [11], and recently by Uji's group [13] for the Hall effect in (TMTSF) 2 ClO 4 . In our opinion, some non-Fermi-liquid effects were also observed in the LMA resistive experiments in the Q1D compound (Per) 2 Au(mnt) 2 by Graf et al. [14].A non-Fermi-liquid theory of the LMA phenomenon was suggested in Ref. [15]. In particular, we showed [15] that an inverse electron-electron scattering time increased at the LMA directions of a magnetic field due to some commensurability effects in a "one-dimensionalized" electron spectrum in a Q1D conductor, resulting from Bragg reflections. Yakovenko studied the same "commensurability" effects in several thermodynamic properties of a Q1D conductor [16], including specific heat (see also Refs. [17,18]). Note that the physical conclusion of the work [16] was similar to that of Ref. [15], that a Q1D metal became more 1D at the LMA directions of the field. There are two main goals of the current article. The first one is that we consider the case of high magnetic fields and come to the conclusion that, at directions of the magnetic field far from one of the LMAs, the corrections to specific heat from electron...
