Quantum half-orphans in kagome antiferromagnets
Pranay Patil, Fabien Alet, Sylvain Capponi +1
We numerically study the effects of non-magnetic impurities (vacancies) in the spin- Heisenberg antiferromagnet on the kagomé lattice. For a range of low but nonzero temperature…
A Semiconductor Topological Photonic Ring Resonator
M. Jalali Mehrabad, A. P. Foster, R. Dost +6
Unidirectional photonic edge states arise at the interface between two topologically-distinct photonic crystals. Here, we demonstrate a micron-scale GaAs photonic ring resonator, c…
Hilbert Space Fragmentation and Ashkin-Teller Criticality in Fluctuation Coupled Ising Models
Pranay Patil, Anders W. Sandvik
We discuss the effects of exponential fragmentation of the Hilbert space on phase transitions in the context of coupled ferromagnetic Ising models in arbitrary dimension with speci…
Obstacles to quantum annealing in a planar embedding of XORSAT
Pranay Patil, Stefanos Kourtis, Claudio Chamon +2
We introduce a planar embedding of the k-regular k-XORSAT problem, in which solutions are encoded in the ground state of a classical statistical mechanics model of reversible logic…
Numerical Investigations of SO(4) Emergent Extended Symmetry in Spin-1/2 Heisenberg Antiferromagnetic Chains
Pranay Patil, Emanuel Katz, Anders W. Sandvik
The antiferromagnetic Heisenberg chain is expected to have an extended symmetry, [SU(2)xSU(2)]/Z 2 , in the infrared limit, whose physical interpretation is that the spin and dimer…
