Confinement transition in a Kitaev-like honeycomb model with bond anisotropy
Gideon Wachtel, Dror Orgad
The honeycomb model is known to have both deconfined spin liquid and confined phases. We study here a confinement transition between the Kitaev spin liquid and a dimerized ph…
Pseudo-Landau levels of Bogoliubov quasiparticles in strained nodal superconductors
Geremia Massarelli, Gideon Wachtel, John Y. T. Wei +1
Motivated by theory and experiments on strain induced pseudo-Landau levels (LLs) of Dirac fermions in graphene and topological materials, we consider its extension for Bogoliubov q…
Optimal inhomogeneity for pairing in Hubbard systems with next-nearest-neighbor hopping
Gideon Wachtel, Shirit Baruch, Dror Orgad
Previous studies have shown that bipartite Hubbard systems with inhomogeneous hopping amplitudes can exhibit higher pair-binding energies than the uniform model. Here we examine wh…
Quantum spin liquid signatures in Kitaev-like frustrated magnets
Matthias Gohlke, Gideon Wachtel, Youhei Yamaji +2
Motivated by recent experiments on -RuCl, we investigate a possible quantum spin liquid ground state of the honeycomb-lattice spin model with bond-dependent interactions. We…
Magnetic and nematic orders of the 2DEG at oxide (111) surfaces and interfaces
Nazim Boudjada, Gideon Wachtel, Arun Paramekanti
Recent experiments have explored two-dimensional electron gases (2DEGs) at oxide (111) surfaces and interfaces, finding evidence for hexagonal symmetry breaking in SrTiO at low…
Path to stable quantum spin liquids in spin-orbit coupled correlated materials
Andrei Catuneanu, Youhei Yamaji, Gideon Wachtel +2
The spin liquid phase is one of the prominent strongly interacting topological phases of matter whose unambiguous confirmation is yet to be reached despite intensive experimental e…
Nodal-line pairing with 1D-3D coupled Fermi surfaces: a model motivated by Cr-based superconductors
Gideon Wachtel, Yong Baek Kim
Motivated by the recent discovery of a new family of Chromium based superconductors, we consider a two-band model, where a band of electrons dispersing only in one direction intera…
Long-range order and pinning of charge-density waves in competition with superconductivity
Yosef Caplan, Gideon Wachtel, Dror Orgad
Recent experiments show that charge-density-wave correlations are prevalent in underdoped cuprate superconductors. The correlations are short ranged at weak magnetic fields but the…
Signatures of thermally excited vortices in a superconductor with competing orders
Gideon Wachtel, Dror Orgad
Experimental evidence for the existence of a fluctuating charge-density wave order in the pseudogap regime of YBaCuO has renewed interest in its interplay with supe…
Transverse thermoelectric transport in a model of many competing order parameters
Gideon Wachtel, Dror Orgad
Coexisting fluctuations towards various ordered states are ubiquitous in strongly correlated electronic systems. In particular, measurements of underdoped cuprate high-temperature…
The Role of the Core Energy in the Vortex Nernst Effect
Gideon Wachtel, Dror Orgad
We present an analytical study of diamagnetism and transport in a film with superconducting phase fluctuations, formulated in terms of vortex dynamics within the Debye-Hückle appro…
Superfluid stiffness renormalization and critical temperature enhancement in a composite superconductor
Gideon Wachtel, Assaf Bar-Yaacov, Dror Orgad
We study a model of a composite system constructed from a "pairing layer" of disconnected attractive-U Hubbard sites that is coupled by single-particle tunneling, t_perp, to a diso…
Inhomogeneous Phases in a Double-Exchange Magnet with Long Range Coulomb Interactions
Gideon Wachtel, Dror Orgad, D. I. Golosov
We consider a model with competing double-exchange (ferromagnetic) and super-exchange (anti-ferromagnetic) interactions in the regime where phase separation takes place. The presen…
