Deconfined quantum criticality in Ising gauge theory entangled with single-component fermions
Umberto Borla, Snir Gazit, Sergej Moroz
We highlight the exotic quantum criticality of quasi-two-dimensional single-component fermions at half-filling that are minimally coupled to a dynamical Ising gauge theory. With th…
Wegner's Ising gauge spins versus Kitaev's Majorana partons: Mapping and application to anisotropic confinement in spin-orbital liquids
Urban F. P. Seifert, Sergej Moroz
Emergent gauge theories take a prominent role in the description of quantum matter, supporting deconfined phases with topological order and fractionalized excitations. A common con…
Noncommutative Field Theory of the Tkachenko Mode: Symmetries and Decay Rate
Yi-Hsien Du, Sergej Moroz, Dung Xuan Nguyen +1
We construct an effective field theory describing the collective Tkachenko oscillation mode of a vortex lattice in a two-dimensional rotating Bose-Einstein condensate in the long-w…
Higgs Condensates are Symmetry-Protected Topological Phases: I. Discrete Symmetries
Ruben Verresen, Umberto Borla, Ashvin Vishwanath +2
Where in the landscape of many-body phases of matter do we place the Higgs condensate of a gauge theory? On the one hand, the Higgs phase is gapped, has no local order parameter, a…
Fractionalized holes in one-dimensional gauge theory coupled to fermion matter -- deconfined dynamics and emergent integrability
Aritra Das, Umberto Borla, Sergej Moroz
We investigate the interplay of quantum one-dimensional discrete gauge fields and fermion matter near full filling in terms of deconfined fractionalized hole excitat…
Fragmentation and emergent integrable transport in the weakly tilted Ising chain
Alvise Bastianello, Umberto Borla, Sergej Moroz
We investigate emergent quantum dynamics of the tilted Ising chain in the regime of a weak transverse field. Within the leading order perturbation theory, the Hilbert space is frag…
