Phase transitions in the frustrated Ising model on the square lattice
Songbo Jin, Arnab Sen, Wenan Guo +1
We consider the thermal phase transition from a paramagnetic to stripe-antiferromagnetic phase in the frustrated two-dimensional square-lattice Ising model with competing interacti…
Coulomb phase diagnostics as function of temperature, interaction range and disorder
Arnab Sen, R. Moessner, S. L. Sondhi
The emergent gauge field characteristic of the Coulomb phase of spin ice betrays its existence via pinch points in the spin structure factor in reciprocal space which t…
Geometric Influences II: Correlation Inequalities and Noise Sensitivity
Nathan Keller, Elchanan Mossel, Arnab Sen
In a recent paper, we presented a new definition of influences in product spaces of continuous distributions, and showed that analogues of the most fundamental results on discrete…
Vacancy-induced spin textures and their interactions in a classical spin liquid
Arnab Sen, Kedar Damle, R. Moessner
Motivated by experiments on the archetypal frustrated magnet SrCrGaO (SCGO), we study the classical Heisenberg model on the pyrochlore slab (Kagomé bilayer)…
