Braiding fractional quantum Hall quasiholes on a superconducting quantum processor
Ammar Kirmani, Derek S. Wang, Pouyan Ghaemi +1
Direct experimental detection of anyonic exchange statistics in fractional quantum Hall systems by braiding the excitations and measuring the wave-function phase is an enormous cha…
Engineering quasi-steady-state correlations in uncorrelated thermal states using stochastic driving
Armin Rahmani
Nonequilibrium quantum dynamics can give rise to the emergence of novel steady states. We propose a scheme for driving an initially uncorrelated thermal state to generate customize…
Creating and manipulating a Laughlin-type fractional quantum Hall state on a quantum computer with linear depth circuits
Armin Rahmani, Kevin J. Sung, Harald Putterman +3
Here we present an efficient quantum algorithm to generate an equivalent many-body state to Laughlin's fractional quantum Hall state on a digitized quantum computer. Our al…
Interacting Majorana Fermions
Armin Rahmani, Marcel Franz
Majorana fermions are the real (in a mathematical sense) counterparts of complex fermions like ordinary electrons. The promise of topological quantum computing has lead to substant…
Phase diagrams of Majorana-Hubbard ladders
Armin Rahmani, Dmitry Pikulin, Ian Affleck
Models of interacting Majorana modes may be realized in vortex lattices in superconducting films in contact with topological insulators and may be tuned to the strong-interaction r…
Majorana-Hubbard model on the square lattice
Ian Affleck, Armin Rahmani, Dmitry Pikulin
We study a tight-binding model of interacting Majorana (Hermitian) modes on a square lattice. The model may have an experimental realization in a superconducting-film--topological-…
Phase Diagram of the Interacting Majorana Chain Model
Armin Rahmani, Xiaoyu Zhu, Marcel Franz +1
The Hubbard chain and spinless fermion chain are paradigms of strongly correlated systems, very well understood using Bethe ansatz, Density Matrix Renormalization Group (DMRG) and…
Emergent Supersymmetry from Strongly Interacting Majorana Zero Modes
Armin Rahmani, Xiaoyu Zhu, Marcel Franz +1
We show that a strongly interacting chain of Majorana zero modes exhibits a supersymmetric quantum critical point corresponding to the tricritical Ising model, whic…
Anyonic Liquids in Nearly Saturated Spin Chains
Armin Rahmani, Adrian E. Feiguin, Cristian D. Batista
Most Heisenberg-like spin chains flow to a universal free-fermion fixed point near the magnetic-field induced saturation point. Here we show that an exotic fixed point, characteriz…
A Renormalization-Group Study of the Symmetry-Breaking Order Parameters in Spin-Orbit Coupled Iridates and Related Systems
Tanmoy Das, Armin Rahmani
We study the competition between various forms of density-wave-like order parameters that may arise in multi-orbital correlated materials with strong spin-orbit coupling (SOC) with…
Low-energy theory of a two-dimensional itinerant chiral magnet
Armin Rahmani, Rodrigo A. Muniz, Ivar Martin
Effective actions, such as nonlinear sigma models, are important tools in studying low-energy fluctuations of magnetically ordered states. Here we derive an effective action for th…
Anyons in integer quantum Hall magnets
Armin Rahmani, Rodrigo A. Muniz, Ivar Martin
Strongly correlated fractional quantum Hall liquids support fractional excitations, which can be understood in terms of adiabatic flux insertion arguments. A second route to fracti…
Universal Renyi mutual information in classical systems: the case of kagome ice
Armin Rahmani, Gia-Wei Chern
We study the Renyi mutual information of classical systems characterized by a transfer matrix. We first establish a general relationship between the Renyi mutual information of suc…
Junctions of multiple quantum wires with different Luttinger parameters
Chang-Yu Hou, Armin Rahmani, Adrian E. Feiguin +1
Within the framework of boundary conformal field theory, we evaluate the conductance of stable fixed points of junctions of two and three quantum wires with different Luttinger par…
Fractionalization in spontaneous integer quantum Hall systems
Rodrigo A. Muniz, Armin Rahmani, Ivar Martin
It is widely believed that integer quantum Hall systems do not have fractional excitations. Here we show the converse to be true for a class of systems where integer quantum Hall e…
General method for calculating the universal conductance of strongly correlated junctions of multiple quantum wires
Armin Rahmani, Chang-Yu Hou, Adrian Feiguin +3
We develop a method to extract the universal conductance of junctions of multiple quantum wires, a property of systems connected to reservoirs, from static ground-state computation…
