There is a large variety of quantum and classical systems in which the quenched disorder
plays a dominant rôle over quantum, thermal, or stochastic fluctuations: these systems …

Topological quantum memory can protect information against local errors up to finite error
thresholds. Such thresholds are usually determined based on the success of decoding …

An algebraic theory of dualities is developed based on the notion of bond algebras. It deals
with classical and quantum dualities in a unified fashion explaining the precise connection …

A bstract We discuss two-dimensional conformal field theories (CFTs) which are invariant
under gauging a non-invertible global symmetry. At every point on the orbifold branch of c …

We show that disordered flat phases in crystal surfaces are equivalent to valence-bond-type
phases in integer and half-integer spin quantum chains. In the quantum spin representation …

We propose a global measure for quantum correlations in multipartite systems, which is
obtained by suitably recasting the quantum discord in terms of relative entropy and local von …

The phase diagram for a general model for cuprates is derived in a mean-field
approximation. A phase-violating time reversal without breaking translational symmetry is …

Eigenspectra of the critical quantum Ashkin-Teller and Potts chains with free boundaries can
be obtained from that of the XXZ chain with free boundaries and a complex surface field. By …

Critical phenomena arise in a wide variety of physical systems. Classi cal examples are the
liquid-vapour critical point or the paramagnetic ferromagnetic transition. Further examples …

We construct an exactly solvable lattice model for a deconfined quantum critical point
(DQCP) in (1+ 1) dimensions. This DQCP occurs in an unusual setting, namely, at the edge …
