Markovian dissipation can stabilize a (localization) quantum phase transition
Naushad A. Kamar, Mostafa Ali, Mohammad Maghrebi
Quantum phase transitions are a cornerstone of many-body physics at low temperatures but have remained elusive far from equilibrium. Driven open quantum systems -- a prominent non-…
Entanglement, information and non-equilibrium phase transitions in long-range open quantum Ising chains
Daniel A. Paz, Benjamin E. Maves, Naushad A. Kamar +2
Non-equilibrium phase transitions of open quantum systems generically exhibit diverging classical but not quantum correlations. Still entanglement -- characterizing the latter corr…
Signatures of Quantum Phase Transitions in Driven Dissipative Spin Chains
Mostafa Ali, Naushad A. Kamar, Alireza Seif +1
Open driven quantum systems have defined a powerful paradigm of nonequilibrium phases and phase transitions; however, quantum phase transitions are generically not expected in this…
Mobile Impurity in a Two-Leg Bosonic Ladder
Naushad Ahmad Kamar, Adrian Kantian, Thierry Giamarchi
We study the dynamics of a mobile impurity in a two-leg bosonic ladder. The impurity moves both along and across the legs and interacts with a bath of interacting bosonic particles…
Dynamics of a Mobile Impurity in a Two Leg Bosonic Ladder
Naushad Ahmad Kamar, Adrian Kantian, Thierry Giamarchi
We have analyzed the behavior of a mobile quantum impurity in a bath formed by a two-leg bosonic ladder by a combination of field theory (Tomonaga-Luttinger liquid) and numerical (…
Time dependent local potential in a Tomonaga-Luttinger liquid
Naushad Ahmad Kamar, Thierry Giamarchi
We study the energy deposition in a one dimensional interacting quantum system with a point like potential modulated in amplitude. The point like potential at position has a…
