Quantum quench in a driven Ising chain
Neil J. Robinson, Isaac Pérez Castillo, Edgar Guzmán-González
We consider the Ising chain driven by oscillatory transverse magnetic fields. For certain parameter regimes, we reveal a hidden integrable structure in the problem, which allows ac…
Laser-Induced Transient Magnons in Sr3Ir2O7 Throughout the Brillouin Zone
D. G. Mazzone, D. Meyers, Y. Cao +32
Although ultrafast manipulation of magnetism holds great promise for new physical phenomena and applications, targeting specific states is held back by our limited understanding of…
On computing non-equilibrium dynamics following a quench
Neil J. Robinson, Albertus J. J. M. de Klerk, Jean-Sébastien Caux
Computing the non-equilibrium dynamics that follows a quantum quench is difficult, even in exactly solvable models. Results are often predicated on the ability to compute overlaps…
Lack of thermalization in (1+1)-d QCD at large
Axel Cortés Cubero, Neil J. Robinson
Motivated by recent works aimed at understanding the status of equilibration and the eigenstate thermalization hypothesis in theories with confinement, we return to the 't Hooft mo…
Ladder-like optical conductivity in the spin-fermion model
Laura Classen, Neil J. Robinson, Alexei M. Tsvelik
In the nested limit of the spin-fermion model for the cuprates, one-dimensional physics in the form of half-filled two-leg ladders emerges. We show that the renormalization group f…
Characterizing the quantum field theory vacuum using temporal Matrix Product states
Emanuele Tirrito, Neil J. Robinson, Maciej Lewenstein +2
In this paper we construct the continuous Matrix Product State (MPS) representation of the vacuum of the field theory corresponding to the continuous limit of an Ising model. We do…
Structure of eta' mesonic nuclei in a relativistic mean field theory
Daisuke Jido, Hanayo Masutani, Satoru Hirenzaki
The structure and the energy spectrum of the mesonic nuclei are investigated in a relativistic mean field theory. One expects a substantial attraction for the $η^{\pri…
Non-Topological Majorana Zero Modes in Inhomogeneous Spin Ladders
Neil J. Robinson, Alexander Altland, Reinhold Egger +6
We show that the coupling of homogeneous Heisenberg spin-1/2 ladders in different phases leads to the formation of interfacial zero energy Majorana bound states. Unlike Majorana bo…
Nonthermal states arising from confinement in one and two dimensions
Andrew J. A. James, Robert M. Konik, Neil J. Robinson
We show that confinement in the quantum Ising model leads to nonthermal eigenstates, in both continuum and lattice theories, in both one (1D) and two dimensions (2D). In the ordere…
Magnetism in artificial Ruddlesden-Popper iridates leveraged by structural distortions
D. Meyers, Yue Cao, G. Fabbris +18
We report on the tuning of magnetic interactions in superlattices composed of single and bilayer SrIrO inter-spaced with SrTiO. Magnetic scattering shows predominately -…
Umklapp scattering as the origin of -linear resistivity in the normal state of high- cuprate superconductors
T. Maurice Rice, Neil J. Robinson, Alexei M. Tsvelik
The high-temperature normal state of the unconventional cuprate superconductors has resistivity linear in temperature , which persists to values well beyond the Mott-Ioffe-Regel…
Non-perturbative methodologies for low-dimensional strongly-correlated systems: From non-abelian bosonization to truncated spectrum methods
Andrew J. A. James, Robert M. Konik, Philippe Lecheminant +2
We review two important non-perturbative approaches for extracting the physics of low-dimensional strongly correlated quantum systems. Firstly, we start by providing a comprehensiv…
Excitations in the Yang-Gaudin Bose gas
Neil J. Robinson, Robert M. Konik
We study the excitation spectrum of two-component delta-function interacting bosons confined to a single spatial dimension, the Yang-Gaudin Bose gas. We show that there are pronoun…
Thermalization and light cones in a model with weak integrability breaking
Bruno Bertini, Fabian H. L. Essler, Stefan Groha +1
We employ equation of motion techniques to study the non-equilibrium dynamics in a lattice model of weakly interacting spinless fermions. Our model provides a simple setting for an…
Motion of a distinguishable impurity in the Bose gas: Arrested expansion without a lattice and impurity snaking
Neil J. Robinson, Jean-Sébastien Caux, Robert M. Konik
We consider the real time dynamics of an initially localized distinguishable impurity injected into the ground state of the Lieb-Liniger model. Focusing on the case where integrabi…
Prethermalization and thermalization in models with weak integrability breaking
Bruno Bertini, Fabian H. L. Essler, Stefan Groha +1
We study the effects of integrability breaking perturbations on the non-equilibrium evolution of many-particle quantum systems. We focus on a class of spinless fermion models with…
"Quasi-particle breakdown" in the quasi-one-dimensional Ising ferromagnet CoNbO
Neil J. Robinson, Fabian H. L. Essler, Ivelisse Cabrera +1
We present experimental and theoretical evidence that an interesting quantum many-body effect -- quasi-particle breakdown -- occurs in the quasi-one-dimensional spin-1/2 Ising-like…
Quench Dynamics in a Model with Tuneable Integrability Breaking
F. H. L. Essler, S. Kehrein, S. R. Manmana +1
We consider quantum quenches in an integrable quantum chain with tuneable-integrability-breaking interactions. In the case where these interactions are weak, we demonstrate that at…
Finite wave vector pairing in doped two-leg ladders
N. J. Robinson, F. H. L. Essler, E. Jeckelmann +1
We consider the effects of Umklapp processes in doped two-leg fermionic ladders. These may emerge either at special band fillings or as a result of the presence of external periodi…
Smooth electron waveguides in graphene
R. R. Hartmann, N. J. Robinson, M. E. Portnoi
We present exact analytical solutions for the zero-energy modes of two-dimensional massless Dirac fermions fully confined within a smooth one-dimensional potential V(x)= - α/cosh(β…
