“Ising anyons in frustration-free Majorana-dimer models”
Dimer models have long been a fruitful playground for understanding topological physics. We introduce a new class of dimer models -termed Majorana-dimer models -where the dimers represent pairs of Majorana modes, to capture the physics of strongly interacting Majoranas. We find that the simplest examples of such systems realize an intriguing, intrinsically fermionic phase of matter that can be ...
متن کاملHigh order perturbation study of the frustrated quantum Ising chain
In this paper, using high order perturbative series expansion method, the critical exponents of the order parameter and susceptibility in transition from ferromagnetic to disordered phases for 1D quantum Ising model in transverse field, with ferromagnetic nearest neighbor and anti-ferromagnetic next to nearest neighbor interactions, are calculated. It is found that for small value of the frustr...
متن کاملFrustration, area law, and interference in quantum spin models.
We study frustrated quantum systems from a quantum information perspective. Within this approach, we find that highly frustrated systems do not follow any general "area law" of block entanglement, while weakly frustrated ones have area laws similar to those of nonfrustrated systems away from criticality. To calculate the block entanglement in systems with degenerate ground states, typical in fr...
متن کاملApplication of the Interface Approach in Quantum Ising models
We investigate phase transitions in the Ising model and the ANNNI model in transverse field using the interface approach. The exact result of the Ising chain in a transverse field is reproduced. We find that apart from the interfacial energy, there are two other response functions which show simple scaling behaviour. For the ANNNI model in a transverse field, the phase diagram can be fully stud...
متن کاملQuantum simulation of transverse Ising models with Rydberg atoms
Quantum Isingmodels are canonicalmodels for the study of quantumphase transitions (Sachdev 1999QuantumPhase Transitions (Cambridge: CambridgeUniversity Press)) and are the underlying concept formany analogue quantumcomputing and quantum annealing ideas (Tanaka et al Quantum SpinGlasses, Annealing andComputation (Cambridge: CambridgeUniversity Press)). Here we focus on the implementation offinit...
