Dynamical susceptibility and quantum Fisher information in the Su-Schrieffer-Heeger model with Hatsugai-Kohmoto interactions
Sepide Mohamadi, Jahanfar Abouie
We investigate the dynamical spin and charge susceptibilities and the associated quantum Fisher information in a class of interacting lattice models, with a primary focus on the Su…
Emergence of prethermal time quasicrystalline order in a quasiperiodically driven non-interacting spin chain
Davood Marripour, Jahanfar Abouie
We study prethermal time quasicrystalline (TQC) order in a quasiperiodically driven chain of non-interacting spin-1/2 particles. The drive consists of two parts, switched on and of…
Analytic Theory and cQED Implementation of a Two-Qubit Refrigerator: Sub-100 mK Cavity Cooling from a 4 K Bath
Daryoosh Vashaee, Jahanfar Abouie
We develop a theoretical framework for cooling a microwave cavity mode using a Poisson stream of internally correlated pairs of two-level systems and analyze its performance under…
Reservoir-Engineered Refrigeration of a Superconducting Cavity with Double-Quantum-Dot Spin Qubits
Daryoosh Vashaee, Jahanfar Abouie
We present an analytically tractable theory of reservoir-engineered refrigeration of a superconducting microwave cavity and map it onto a realistic solid-state implementation based…
Spin Glasses: Disorder, Frustration, and Nonequilibrium Complexity
Naeimeh Tahriri, Vahid Mahdikhah, Jahanfar Abouie +1
Spin glasses occupy a unique place in condensed matter: they freeze collectively while remaining struc-turally disordered, and they exhibit slow, history-dependent dynamics that re…
From time crystals to time quasicrystals: Exploring quasiperiodic phases in transverse field Ising chains
Davood Marripour, Jahanfar Abouie
Time quasicrystals (TQCs) represent a compelling extension of the concept of time crystals (TCs). While TCs break discrete time-translation symmetry by exhibiting a periodic respon…
