Exact group invariant scar towers in two dimensional gauge theories
João Barata, Kiryl Pakrouski, Andrey V. Sadofyev
We construct exact many-body scar towers in two dimensional gauge theories with two flavors of massless fundamental fermions. For oppositely charged fermions, the scar subspace is…
Unconventional superconducting correlations in fermionic many-body scars
Kiryl Pakrouski, K. V. Samokhin
Weak ergodicity breaking in interacting quantum systems may occur due to the existence of a subspace dynamically decoupled from the rest of the Hilbert space. In two-orbital spinfu…
Certain BCS wavefunctions are quantum many-body scars
Kiryl Pakrouski, Zimo Sun
We construct many-body scar states in multi-flavour fermionic lattice models that possess strong magnetic or superconducting correlations of a given type specified by a unitary mat…
Stability of the many-body scars in fermionic spin-1/2 models
Patrice Kolb, Kiryl Pakrouski
We study the stability of the many-body scars in spin-1/2 fermionic systems under the most typical perturbations in relevant materials. We find that some families of scars are comp…
Majorana Scars as Group Singlets
Z. Sun, F. K. Popov, I. R. Klebanov +1
In some quantum many-body systems, the Hilbert space breaks up into a large ergodic sector and a much smaller scar subspace. It has been suggested [arXiv:2007.00845] that the two s…
Approximate two-body generating Hamiltonian for the PH-Pfaffian wavefunction
Kiryl Pakrouski
We present two 2-body Hamiltonians that approximate the exact PH-Pfaffian wavefunction with their ground states for all the system sizes where this wavefunction has been numericall…
Group theoretic approach to many-body scar states in fermionic lattice models
Kiryl Pakrouski, Preethi N. Pallegar, Fedor K. Popov +1
It has been shown [arXiv:2007.00845] that three families of highly symmetric states are many-body scars for any spin-1/2 fermionic Hamiltonian of the form , where is a…
Energetics of the PH-Pfaffian state and the 5/2-fractional quantum Hall effect
Edward H. Rezayi, Kiryl Pakrouski, F. D. M. Haldane
We present a method for the exact construction of the fully particle-hole symmetric PH-Pfaffian ground state and its charged excitations on a sphere. We adopt the Moore-Read state,…
Many Body Scars as a Group Invariant Sector of Hilbert Space
Kiryl Pakrouski, Preethi N. Pallegar, Fedor K. Popov +1
We present a class of Hamiltonians for which a sector of the Hilbert space invariant under a Lie group , which is not a symmetry of , possesses the essential properties o…
Hagedorn Temperature in Large Majorana Quantum Mechanics
Gabriel Gaitan, Igor R. Klebanov, Kiryl Pakrouski +2
We discuss two types of quantum mechanical models that couple large numbers of Majorana fermions and have orthogonal symmetry groups. In models of vector type, only one of the symm…
Automatic design of Hamiltonians
Kiryl Pakrouski
We formulate an optimization problem of Hamiltonian design based on the variational principle. Given a variational ansatz for a Hamiltonian we construct a loss function to be minim…
Spectrum of Majorana Quantum Mechanics with Symmetry
Kiryl Pakrouski, Igor R. Klebanov, Fedor Popov +1
We study the quantum mechanics of 3-index Majorana fermions governed by a quartic Hamiltonian with symmetry. Similarly to the Sachdev-Ye-Kitaev model, this tenso…
Experimental Signatures of the Inverted Phase in InAs/GaSb Coupled Quantum Wells
Matija Karalic, Susanne Mueller, Christopher Mittag +8
Transport measurements are performed on InAs/GaSb double quantum wells at zero and finite magnetic fields applied parallel and perpendicular to the quantum wells. We investigate a…
The enigmatic 12/5 fractional quantum Hall effect
Kiryl Pakrouski, Matthias Troyer, Yang-Le Wu +2
We numerically study the fractional quantum Hall effect at filling factors and 13/5 (the particle-hole conjugate of 12/5) in high-quality two-dimensional GaAs heterostruct…
Two-dimensional epitaxial superconductor-semiconductor heterostructures: A platform for topological superconducting networks
J. Shabani, M. Kjaergaard, H. J. Suominen +12
Progress in the emergent field of topological superconductivity relies on synthesis of new material combinations, combining superconductivity, low density, and spin-orbit coupling…
The Phase Diagram of the Fractional Quantum Hall Effect: Effects of Landau Level Mixing and Non-Zero Width
Kiryl Pakrouski, Michael R. Peterson, Thierry Jolicoeur +3
Interesting non-Abelian states, e.g., the Moore-Read Pfaffian and the anti-Pfaffian, offer candidate descriptions of the fractional quantum Hall state. But the significant…
A model project for reproducible papers: critical temperature for the Ising model on a square lattice
M. Dolfi, J. Gukelberger, A. Hehn +8
In this paper we present a simple, yet typical simulation in statistical physics, consisting of large scale Monte Carlo simulations followed by an involved statistical analysis of…
