Dissipative Majorana Chain---Anomalies and Non-Invertible Symmetries
We study symmetries and anomalies of dissipative Majorana chains described by Lindblad dynamics.Spacetime Quasicrystals and Computational Complexity Theory in the Road Towards Quantum Gravity
Part I: Semiclassical Gravity Efficiently Solves $\mathsf{NP}$-Complete Problems Assuming the gravitational field is classical and that it couples to quantum fields via the semiclassical Einstein…Fast holographic inversion of superconducting domes
A holographic superconductor whose scalar mass depends on the gauge field strength, $M(\Fsq)$, reproduces a superconducting dome for a suitable $M$, and recovering that $M$ from a given dome has so…Can we make sense out of negative kinetic energy?
Many Quantum Field Theory models, either designed to improve the ultraviolet behavior via higher derivative terms or aimed at providing unified descriptions of Gravity, inevitably introduce…Black hole radial geometry from a quantum spin chain
We show that the radial differential equation for a scalar field in an anti-de Sitter black brane background can be encoded in an exactly solvable semi-infinite spin chain independent of…Scattering entanglement entropy between one particle species and the others
We construct the entanglement entropy of a general scattering process between one particle species (denoted as $A$) and the rest of the final state.Reconstruction of Black Hole Islands from Hawking Radiation via the Algebraic Petz Map
The island proposal guarantees a unitary Page curve for evaporating black holes, implying that operators deep behind the horizon must be fully reconstructable from asymptotic Hawking radiation.Quantum geometry at arbitrary genus - I: Anharmonic potentials
In quantum mechanics of genus-1 potentials, perturbation theory around the topologically trivial saddle and non-perturbative instanton saddle are constructively related via the P/NP relation.Spontaneous Hawking Radiation from Dynamical Black-Hole Formation in Quantum Spin Systems
We show that Hawking radiation spontaneously generated by dynamical black-hole formation can be realized in a local quantum spin model.Relative-Entropy Flow Across the Page Transition
We develop a computational framework for the quantum relative entropy based on the replica trick and apply it to analyze the evaporation process method of Jackiw-Teitelboim black holes.Universal critical $g$ factor for spin-1/2 Aharonov-Bohm bound states
Whether the spin-1/2 Aharonov-Bohm Hamiltonian supports bound states has remained controversial since Hagen concluded that no such states exist for a Dirac particle.Sampling SU(N) gauge theory on a 2D lattice from independent plaquettes via holonomies and corner reweighting
In the Wilson formulation of lattice gauge theory, the fundamental degrees of freedom are group-valued link variables, while the action is a sum over the trace of the plaquettes, the smallest Wilson…An efficient Hamiltonian-based quantum algorithm for characters of the symmetric group
Consider a quantum state vector proportional to any given column of the character table of the symmetric group ($S_n$), corresponding to a superposition over the irreps weighted by the character…Local universality of non-local quantum resources in rotationally invariant scattering
Elastic scattering can generate entanglement and non-local magic between the spins of the two outgoing particles.Magnus: neutrino oscillation probabilities for any Hermitian Hamiltonian, any number of flavors, and any matter profile
Interpreting neutrino oscillation measurements requires computing the probability that a neutrino born with one flavor is detected with another.Generalised entanglement wedges in three dimensions
Generalized entanglement wedges (GWs), proposed by Bousso and Penington for gravitating regions in general spacetimes, share many properties of ordinary entanglement wedges, including nesting…Quantum Algorithms for Finding Vacua in the ADK Landscape
We study quantum algorithms for finding a vacuum with a small cosmological constant in the toy model for string Landscape proposed by Arkani-Hamed, Dimopoulos, and Kachru.How to distinguish chaos from integrability using OTOC
The decay of out-of-time-ordered correlators (OTOCs) to a small residual value signals the scrambling of quantum information.Optimal Interferometer Geometry for Gravitationally Induced Quantum Entanglement
The quest for a quantum theory of gravity remains a central challenge in modern physics, driven by the goal of unifying general relativity and quantum mechanics.Majorana bilinears, compact modular seeds and the approach to the Tsirelson bound
In this work we study the Bell-CHSH inequality in the vacuum of the free massive Majorana field in $1+1$ dimensions, taking as the dichotomic observables of the two parties even bilinears of smeared…
