Dirac surface states and nature of superconductivity in noncentrosymmetric BiPd
, 2015 In non-magnetic bulk materials, inversion symmetry protects the spin degeneracy. If the bulk crystal structure lacks a centre of inversion, however, spin-orbit interactions lift the spin degeneracy, leading to a Rashba metal whose Fermi surfaces exhibit ...

Search for ambient superconductivity in the Lu–N–H system
, 2023 Motivated by the recent report of room-temperature superconductivity at near-ambient pressure in N-doped lutetium hydride, we performed a comprehensive, detailed study of the phase diagram of the Lu–N–H system, looking for superconducting phases.

Numerical studies of superfluids and superconductors [PDF]
, 2001 In this thesis we demonstrate the power of the Gross-Pitaevskii and the time-dependent Ginzburg-Landau equations by numerically solving them for various fundamental problems related to superfluidity and superconductivity.

Competing Orders In Underdoped (ba1-xkx)fe 2as2
, 2015 We report 75As Nuclear Magnetic Resonance (NMR) measurements in the high-Tc superconductor (Ba1-xKx)Fe 2As2 in the underdoped regime. A structural transition at Ts ≃110 K is followed by an antiferromagnetic (AFM) order at TN ≃102 K for our x = 0.16 ...

Multicritical matrix models and the chiral phase transition
, 1998 Universality of multicritical unitary matrix models is shown and a new scaling behavior is found in the microscopic region of the spectrum, which may be relevant for the low energy spectrum of the Dirac operator at the chiral phase ...

Spontaneous symmetry breaking and Nambu–Goldstone bosons in quantum many-body systems
, 2010 Spontaneous symmetry breaking is a general principle that constitutes the underlying concept of a vast number of physical phenomena ranging from ferromagnetism and superconductivity in condensed matter physics to the Higgs mechanism in the standard model

, 2009 The archetypal high temperature superconductor Bi₂Sr₂CaCu₂O[subscript[8+δ]] has been extensively investigated. However, until now, little has been known about the behaviour of the magnetic vortices inside the Vortex Glass and liquid state.

, 2006 We have altered the superconductivity of a suspended rope of single walled carbon nanotubes, by coating it with organic polymers. Upon coating, the normal state resistance of the rope changes by less than 20%.

Effective low-energy theory of superconductivity in carbon nanotube ropes
, 2004 We derive and analyze the low-energy theory of superconductivity in carbon nanotube ropes. A rope is modelled as an array of metallic nanotubes, taking into account phonon-mediated as well as Coulomb interactions, and arbitrary Cooper pair hopping ...

, 2005 4 pages, 3 figuresUsing density functional theory we demonstrate that superconductivity in C6Ca is due to a phonon-mediated mechanism with electron-phonon coupling 0.83 and phonon-frequency logarithmic-average 24.7 meV.
