A Single Conformal Coordinate Decodes Outcome-Resolved Measurement-Induced Entanglement
Reyhaneh Khasseh, M. A. Rajabpour
A local measurement of a critical many-body state produces exponentially many microscopic outcomes, each defining a different conditioned quantum state. We ask how much information…
Superfluidity in active quantum flocks
Byjesh N. Radhakrishnan, Reyhaneh Khasseh, Thomas Schmidt +1
Active quantum matter has very recently emerged at the intersection between bio- and quantum many-body physics, combining the self-organization of living systems with the coherence…
Quantum motility-induced phase separation
Laurin Brunner, Ricard Alert, Reyhaneh Khasseh +1
Motility-induced phase separation (MIPS) describes a central clustering phenomenon in active matter systems where particles spontaneously separate into dense and dilute phases even…
Fugacity-Resolved Stabilizer Entropy in Critical Quantum Chains: Discrete Selberg Sums and Exactly Solvable Rényi Indices
Reyhaneh Khasseh, M. A. Rajabpour
Stabilizer Rényi entropy quantifies the nonstabilizerness of a quantum state through Rényi moments of its Pauli expectation-value distribution. Its standard form sums over Pauli-st…
Semiclassical Langevin dynamics of long-range dissipative time crystals
Reyhaneh Khasseh, Rosario Fazio, Angelo Russomanno
We develop a semiclassical Langevin approach to study finite-size effects in dissipative time-crystalline spin systems. For a spin- model with power-law Lindblad operators, we…
Universal Crossovers of Stabilizer Entropy Beyond Criticality
Reyhaneh Khasseh, E. A. Ramirez Trino, M. A. Rajabpour
Stabilizer Rényi entropy has emerged as a probe of nonstabilizerness in quantum many-body systems, but its scaling structure beyond critical points remains poorly understood compar…
Hidden Conformal Boundary Data in Finite-Temperature Stabilizer Entropy
Reyhaneh Khasseh, M. A. Rajabpour
We study the finite-temperature stabilizer Rényi entropy of the open critical quantum spin chains. At Rényi index one half, this observable probes the distribution of thermal Pauli…
Snapshot renormalization group for quantum matter
Laurin Brunner, Tobias Wiener, Tiago Mendes-Santos +2
Recent advances in quantum simulator experiments enable unprecedented access to quantum many-body states through snapshot measurements of individual many-body configurations. Here,…
Matrix Elements of Fermionic Gaussian Operators in Arbitrary Pauli Bases: A Pfaffian Formula
M. A. Rajabpour, MirAdel Seifi MirJafarlou, Reyhaneh Khasseh
Fermionic Gaussian operators are foundational tools in quantum many-body theory, numerical simulation of fermionic dynamics, and fermionic linear optics. While their structure is f…
Explicit Pfaffian Formula for Amplitudes of Fermionic Gaussian Pure States in Arbitrary Pauli Bases
M. A. Rajabpour, M. A. Seifi Mirjafarlou, Reyhaneh Khasseh
The explicit computation of amplitudes for fermionic Gaussian pure states in arbitrary Pauli bases is a long-standing challenge in quantum many-body physics, with significant impli…
Subsystem Evolution Speed as Indicator of Relaxation
Jiaju Zhang, M. A. Rajabpour, Markus Heyl +1
In studying the time evolution of isolated many-body quantum systems, a key focus is determining whether the system undergoes relaxation and reaches a steady state at a given point…
Efficient Representation of Gaussian Fermionic Pure States in Non-Computational Bases
Babak Tarighi, Reyhaneh Khasseh, M. A. Rajabpour
This paper introduces an innovative approach for representing Gaussian fermionic states, pivotal in quantum spin systems and fermionic models, within a range of alternative quantum…
Active quantum flocks
Reyhaneh Khasseh, Sascha Wald, Roderich Moessner +2
Flocks of animals represent a prominent archetype of collective behavior in the macroscopic classical world, where the constituents, such as birds, concertedly perform motions and…
Identifying quantum many-body integrability and chaos using eigenstates trace distances
Reyhaneh Khasseh, Jiaju Zhang, Markus Heyl +1
While the concepts of quantum many-body integrability and chaos are of fundamental importance for the understanding of quantum matter, their precise definition has so far remained…
Universal logarithmic correction to Rényi (Shannon) entropy in generic systems of critical quadratic fermions
Babak Tarighi, Reyhaneh Khasseh, M. N. Najafi +1
The Rényi (Shannon) entropy, i.e. , of the ground state of quantum systems in local bases normally show a volume-law behavior. For a subsystem of quantum chains at critic…

Reyhaneh Khasseh, Angelo Russomanno, Rosario Fazio
We add quantum fluctuations to a classical period-doubling Hamiltonian time crystal, replacing the classical interacting angular momenta with quantum spins of size . The ful…
Discrete truncated Wigner approach to dynamical phase transitions in Ising models after a quantum quench
Reyhaneh Khasseh, Angelo Russomanno, Markus Schmitt +2
By means of the discrete truncated Wigner approximation we study dynamical phase transitions arising in the steady state of transverse-field Ising models after a quantum quench. St…
Many-body synchronisation in a classical Hamiltonian system
Reyhaneh Khasseh, Rosario Fazio, Stefano Ruffo +1
We study synchronisation between periodically driven, interacting classical spins undergoing a Hamiltonian dynamics. In the thermodynamic limit there is a transition between a regi…

Reyhaneh Khasseh, Saeed H. Abedinpour, B. Tanatar
We investigate the ground-state properties and the collective modes of a two-dimensional two-component Rydberg-dressed Fermi liquid in the dipole-blockade regime. We find instabili…
