Infinite-Level Hierarchy of Solvable Quantum Circuits
Michael A. Rampp, Suhail A. Rather, Pieter W. Claeys
Dual-unitary circuits have emerged as a paradigm of exactly solvable yet non-integrable quantum dynamics. Recently, a generalization of dual unitarity attempting to extend the phen…
Solvable Quantum Circuits from Spacetime Lattices
Michael A. Rampp, Suhail A. Rather, Pieter W. Claeys
In recent years dual-unitary circuits and their multi-unitary generalizations have emerged as exactly solvable yet chaotic models of quantum many-body dynamics. However, a systemat…
Free Cumulants and Full Eigenstate Thermalization from Boundary Scrambling
Felix Fritzsch, Gabriel O. Alves, Michael A. Rampp +1
Out-of-time-order correlation functions (OTOCs) and their higher-order generalizations present important probes of quantum information dynamics and scrambling. We introduce a solva…
Geometric constructions of generalized dual-unitary circuits from biunitarity
Michael A. Rampp, Suhail A. Rather, Pieter W. Claeys
We present a general framework for constructing solvable lattice models of chaotic many-body quantum dynamics with multiple unitary directions using biunitary connections. We show…
The entanglement membrane in exactly solvable lattice models
Michael A. Rampp, Suhail A. Rather, Pieter W. Claeys
Entanglement membrane theory is an effective coarse-grained description of entanglement dynamics and operator growth in chaotic quantum many-body systems. The fundamental quantity…
Hayden-Preskill recovery in chaotic and integrable unitary circuit dynamics
Michael A. Rampp, Pieter W. Claeys
The Hayden-Preskill protocol probes the capability of information recovery from local subsystems after unitary dynamics. As such it resolves the capability of quantum many-body sys…
From Dual Unitarity to Generic Quantum Operator Spreading
Michael A. Rampp, Roderich Moessner, Pieter W. Claeys
Dual-unitary circuits are paradigmatic examples of exactly solvable yet chaotic quantum many-body systems, but solvability naturally goes along with a degree of non-generic behavio…
Josephson junctions of 2D time-reversal invariant superconductors: signatures of the topological phase
Gabriel F. Rodríguez Ruiz, Michael A. Rampp, A. A. Aligia +2
We determine the current-phase relation (CPR) of two-terminal configurations of Josephson junctions containing two-dimensional (2D) time-reversal invariant topological superconduct…
Integer and fractionalized vortex lattices and off-diagonal long-range order
Michael A. Rampp, Jörg Schmalian
We analyze the implication of off-diagonal long-range order (ODLRO) for inhomogeneous periodic field configurations and multi-component order parameters. For single component order…
Topologically enabled superconductivity
Michael A. Rampp, Elio J. König, Jörg Schmalian
Majorana zero modes are a much sought-after consequence of one-dimensional topological superconductivity. Here, we show that, in turn, zero modes accompanying dynamical instanton e…
