Dynamics of the dissipative two-state system
This paper presents the results of a functional-integral approach to the dynamics of a two-state system coupled to a dissipative environment. It is primarily an extended account of results obtained
Deconfined Quantum Critical Points
TLDR
It is shown that near second-order quantum phase transitions, subtle quantum interference effects can invalidate this paradigm for quantum criticality, and a theory of quantum critical points in a variety of experimentally relevant two-dimensional antiferromagnets is presented.
Determination of jet energy calibration and transverse momentum resolution in CMS
Measurements of the jet energy calibration and transverse momentum resolution in CMS are presented, performed with a data sample collected in proton-proton collisions at a centre-of-mass energy of
Quantum criticality beyond the Landau-Ginzburg-Wilson paradigm
We present the critical theory of a number of zero-temperature phase transitions of quantum antiferromagnets and interacting boson systems in two dimensions. The most important example is the
Non-Abelian statistics and topological quantum information processing in 1D wire networks
The synthesis of a quantum computer remains an ongoing challenge in modern physics. Whereas decoherence stymies most approaches, topological quantum computation schemes evade decoherence at the
Particle-hole symmetry and the nu=5/2 quantum Hall state.
TLDR
The implications of approximate particle-hole symmetry in a half-filled Landau level in which a paired quantum Hall state forms is discussed, and the anti-Pfaffian state, which is degenerate with the Pfaffian in this limit of vanishing Landau-level mixing, is discussed.
Plaquette ordered phase and quantum phase diagram in the spin-1/2 J(1)-J(2) square Heisenberg model.
We study the spin-1/2 Heisenberg model on the square lattice with first- and second-neighbor antiferromagnetic interactions J(1) and J(2), which possesses a nonmagnetic region that has been debated
