Thermal and geometric normal modes of spectral fluctuations in heavy-ion collisions
Rupam Samanta
The transverse momentum spectrum of charged particles in ultra-relativistic heavy-ion collisions fluctuates event-by-event, encoding signatures of underlying collective dynamics. S…
Probing collectivity in heavy-ion collisions with fluctuations of the spectrum
Tribhuban Parida, Rupam Samanta, Jean-Yves Ollitrault
Event-by-event fluctuations in the initial stages of ultrarelativistic nucleus-nucleus collisions depend little on rapidity. The hydrodynamic expansion which occurs in later stages…
Multiplicity fluctuations and rapidity correlations in ultracentral proton-nucleus collisions
Rupam Samanta, Jean-Yves Ollitrault
A collision between a proton and a heavy nucleus at ultrarelativistic energy creates particles whose rapidity distribution is asymmetric, with more particles emitted in the directi…
Transverse momentum fluctuation in ultra-central Pb+Pb collision at the LHC
Rupam Samanta, Somadutta Bhatta, Jiangyon Jia +2
The ATLAS collaboration has recently observed that the variance of the transverse momentum per particle (), when measured as a function of the collision multiplicity ($N_{…
Momentum dependent measures of correlations between mean transverse momentum and harmonic flow in heavy ion collisions
Rupam Samanta, Piotr Bozek
The correlation between the mean transverse momentum and the harmonic flow coefficients is an observable which is of great interest; it is sensitive to shape fluctuations in the in…
NANOGrav spectral index from melting domain walls
E. Babichev, D. Gorbunov, S. Ramazanov +2
We discuss cosmic domain walls described by a tension red-shifting with the expansion of the Universe. These melting domain walls emit gravitational waves with the low-frequency sp…
Non-Gaussian transverse momentum fluctuations from impact parameter fluctuations
Rupam Samanta, João Paulo Picchetti, Matthew Luzum +1
The transverse momentum per particle, , fluctuates event by event in ultrarelativistic nucleus-nucleus collisions, for a given multiplicity. These fluctuations are small and…
Thermalization at the femtoscale seen in high-energy Pb+Pb collisions
Rupam Samanta, Somadutta Bhatta, Jiangyong Jia +2
A collision between two atomic nuclei accelerated at a speed close to that of light creates a dense system of quarks and gluons. Interactions among them are so strong that they beh…
Momentum dependent flow correlations in deformed nuclei at collision energies available at the BNL Relativistic Heavy Ion Collider
Rupam Samanta, Piotr Bozek
Flow fluctuations in ultra-relativistic heavy-ion collision can be probed by studying the momentum dependent correlations or the factorization-breaking coefficients between flow ha…
Probing flow fluctuations through factorization breaking of harmonic flows in heavy-ion collisions
Piotr Bozek, Rupam Samanta
We study factorization-breaking coefficients between the momentum dependent and momentum averaged flow vectors to probe flow fluctuations caused by initial-state fluctuations in he…
Factorization breaking for higher moments of harmonic flow
Piotr Bozek, Rupam Samanta
We study correlations between harmonic flow vectors squared measured at different transverse momenta. One of the flow harmonics squared is taken at a fixed transverse momentum and…
Higher order cumulants of transverse momentum and harmonic flow in relativistic heavy ion collisions
Piotr Bozek, Rupam Samanta
Higher order symmetric cumulants of global collective observables in heavy ion collisions are studied. The symmetric cumulants can be straightforwardly constructed for scalar obser…
Anomalous Hydrodynamics in One Dimensional Electronic Fluid
I. V. Protopopov, R. Samanta, A. D. Mirlin +1
We construct multi-mode viscous hydrodynamics for one dimensional spinless electrons. Depending on the scale, the fluid has six (shortest lengths), four (intermediate, exponentiall…
Thermal Transport in One Dimensional Electronic Fluid
R. Samanta, I. V. Protopopov, A. D. Mirlin +1
We study thermal conductivity for one-dimensional electronic fluid. The many-body Hilbert space is partitioned into bosonic and fermionic sectors that carry the thermal current in…
