Spin Polarons in Flat Band Ferromagnets
Saranesh Prembabu, Rahul Sahay, Stefan Divic +1
Spin polarons are bound states of electrons and spin-flips that form above spin polarized electronic insulators.These bound states conventionally form in one of two settings: in fr…
Topological Phase Transitions and Mixed State Order in a Hubbard Quantum Simulator
Lin Su, Rahul Sahay, Michal Szurek +5
Topological phase transitions challenge conventional paradigms in many-body physics by separating phases that are locally indistinguishable yet globally distinct. Using a quantum s…
Enforced Gaplessness from States with Exponentially Decaying Correlations
Rahul Sahay, Curt von Keyserlingk, Ruben Verresen +1
It is well known that an exponentially localized Hamiltonian must be gapless if its ground state has algebraic correlations. We show that even certain exponentially decaying correl…
Shortcuts to Analog Preparation of Non-Equilibrium Quantum Lakes
Nik O. Gjonbalaj, Rahul Sahay, Susanne F. Yelin
The dynamical preparation of exotic many-body quantum states is a persistent goal of analog quantum simulation, often limited by experimental coherence times. Recently, it was show…
