Parisi formula, disorder chaos and fluctuation for the ground state energy in the spherical mixed p-spin models
Wei-Kuo Chen, Arnab Sen
We show that the limiting ground state energy of the spherical mixed p-spin model can be identified as the infimum of certain variational problem. This complements the well-known P…
Entanglement generation in periodically driven integrable systems: dynamical phase transitions and steady state
Arnab Sen, Sourav Nandy, K. Sengupta
We study a class of periodically driven dimensional integrable models and show that after drive cycles with frequency , pure states with non-area-law entanglement entrop…
Classical spin-liquid on the maximally frustrated honeycomb lattice
J. Rehn, Arnab Sen, Kedar Damle +1
We show that the honeycomb Heisenberg antiferromagnet with , where are first-, second- and third-neighbour couplings respectively, forms a classical spin…
Velocity of excitations in ordered, disordered and critical antiferromagnets
Arnab Sen, Hidemaro Suwa, Anders W. Sandvik
We test three different approaches, based on quantum Monte Carlo simulations, for computing the velocity of triplet excitations in antiferromagnets. We consider the standard $S…
Random Coulomb antiferromagnets: from diluted spin liquids to Euclidean random matrices
J. Rehn, Arnab Sen, Alexei Andreanov +3
We study a disordered classical Heisenberg magnet with uniformly antiferromagnetic interactions which are frustrated on account of their long-range Coulomb form, {\em i.e.} $J(r)\s…
